Full-Stack Applications
End-to-end builds that combine frontend delivery, backend APIs, data models, and deployment workflows. This cluster focuses on systems you can click through and verify.
Car-Match
Impact: Car-Match delivers profile, forum, and message interactions with sub-400ms API response times in validation runs while keeping auth and data flow consistent across the full stack.
Built to solve the "too many disconnected dating features" problem by combining profiles, matching, chat, and forums in one product flow.
What I learned: Keeping auth rules, API contracts, and deployment checklists aligned is the difference between a demo and a usable product.
More details
My role: I built the React experience for profiles, forums, and chat, then implemented the Express endpoints for auth, profile matching, and messaging with JWT-based session protection.
Technical approach: The project uses a React client, Express API, and MongoDB data model for users, events, forums, and messages. Deployment is split between GitHub Pages (frontend) and Render (API) with documented release steps.
Outcomes and proof: API routes for core profile and message paths were measured under ~400ms in local plus Render validation runs. Source and deployment evidence live in GitHub, with production hosting split between GitHub Pages and Render.
Limitations: The current release prioritizes core matching and chat workflows over advanced moderation and broader load testing.
Interactive Pokédex
Impact: The app ships all 151 Gen-1 entries with fast client filtering and theme controls while staying fully compatible with static export deployment.
Built to make browsing the original 151 Pokemon feel instant, even on static hosting, without a custom backend.
What I learned: Mixing build-time data fetches with lightweight client state gives performance and UX without needing a custom backend.
More details
My role: I configured static export for GitHub Pages, implemented build-time data loading from PokéAPI, and built client-side search plus filter behavior for a fast browse experience.
Technical approach: Next.js handles static generation, while lightweight client state powers search and filters. Tailwind CSS drives responsive layout behavior and trailing-slash routing keeps GitHub Pages paths stable.
Outcomes and proof: The production build indexes all 151 Pokemon with build-time + client-side hybrid behavior. You can verify on Live Demo and in the GitHub repository.
Limitations: The scope is intentionally focused on Gen-1 content and does not include deeper battle mechanics or account-based personalization yet.
CIRIS AI contributions
Impact: The contribution set improved first-run setup reliability and made auth issues easier to trace with clearer docs plus token-verification logging.
I joined CIRIS to reduce contributor onboarding friction by improving docs, local setup, and debugging visibility.
What I learned: Documentation quality and observability updates can unblock engineering velocity as much as feature code.
More details
My role: I shipped documentation improvements for JWT auth, added logging around token verification, and contributed Docker Compose support to tighten local developer setup.
Technical approach: Instead of isolated updates, I treated onboarding, observability, and environment setup as one contributor journey and shipped coordinated docs + runtime changes.
Outcomes and proof: Merged contribution history is visible in the CIRIS pull requests, including PR #3. The changes cover docs, Docker local workflow, and auth logging in public repos.
Limitations: As a contributor, I focused on targeted onboarding and reliability tasks rather than owning the entire architecture roadmap.
Front-End Interfaces
UI-first projects focused on interaction quality, accessibility, and visual clarity. These are fast to scan, demo-friendly, and built to explain design decisions clearly.
AnimalSounds
Impact: AnimalSounds delivers instant local playback with browser-persisted favorites, so the experience stays usable even with unstable connectivity.
Built as an offline-first soundboard so kids and families can tap and learn animal sounds instantly without waiting on network calls.
What I learned: Offline-first decisions and base-path-safe deployment rules make demos more reliable across real devices.
More details
My role: I built the full interface using Next.js App Router, NextUI, and Tailwind, then wired local audio assets, keyboard navigation, favorites, and local listening stats.
Technical approach: Core audio files are bundled in the app for offline behavior, optional Pexels enrichment is feature-flagged, and GitHub Pages base-path rules are documented to keep static hosting reliable.
Outcomes and proof: Offline MP3 playback and local favorites persistence are live in the deployed demo and documented in GitHub.
Limitations: The project currently focuses on a curated set of animals and lightweight enrichment, not a full educational curriculum platform.
Professional Portfolio Website
Impact: The project gave me a reusable section system I still reference when shipping new portfolio pages and contact flows.
This was a focused portfolio sandbox where I practiced reusable section patterns before redesigning my current production site.
What I learned: Consistent section patterns and component contracts speed up future site iterations.
More details
My role: I designed and implemented reusable React sections for navigation, projects, experience, and contact with styled-components and Material UI forms.
Technical approach: The site uses componentized section templates, responsive breakpoints, and documented GitHub Pages deployment steps to keep updates repeatable.
Outcomes and proof: The full implementation is available in GitHub with a live deployment at GitHub Pages.
Limitations: This is a reference implementation and does not include all of the newer content, analytics, and case-study depth from the current live portfolio.
CodePen projects
Impact: The collection reduces rework by validating accessibility states and layout behavior in small, disposable prototypes first.
I use these pens as a quick UX lab to test interactions before committing larger features to production repos.
What I learned: Small isolated experiments make production UI decisions faster and safer.
More details
My role: I authored and organized the demos, with emphasis on reusable UI patterns, responsive behavior, and accessibility-focused states.
Technical approach: Each pen isolates one pattern, which keeps iteration fast and makes it easier to promote tested snippets into larger projects and blog walkthroughs.
Outcomes and proof: The public collection is available on CodePen, and selected patterns are referenced across project and blog documentation.
Limitations: CodePen demos are intentionally narrow and are not full production applications with backend integrations.
AI-Enabled Full-Stack Systems
Voice and text workflows where local inference, API orchestration, and privacy constraints matter more than flashy demos.
Convo-Ai
Impact: Convo-Ai keeps speech-to-text, LLM inference, and text-to-speech on-device so conversation data stays local and private.
Built for people who want voice AI without sending conversations to third-party cloud APIs.
What I learned: Local AI systems require careful dependency and runtime documentation to stay reproducible.
More details
My role: I implemented the FastAPI backend, connected Whisper, Ollama, and XTTS v2, and documented local setup so the stack can be reproduced on another machine.
Technical approach: The app exposes HTTP and WebSocket flows, maintains conversation history, and supports optional sentiment hooks while relying on local runtime dependencies like Python, FFmpeg, and Ollama.
Outcomes and proof: Integration and run instructions are documented in the repository, including local-only execution for server plus client.
Limitations: Performance depends on local hardware and model configuration, so setup quality and response speed vary by machine.
Tools & Infrastructure
Labs and utilities used to learn lower-level engineering concepts, deployment reliability, and debugging patterns across environments.
Triangle Shader Lab (WebGPU)
Impact: The lab provides a side-by-side toggle between a minimal triangle and textured cube so pipeline changes can be validated quickly.
Built as a practical graphics lab so I could trace the full WebGPU path from device request to final frame output.
What I learned: Pipeline setup clarity matters more than visual complexity when learning new graphics APIs.
More details
My role: I implemented the WebGPU initialization, pipeline setup, and shader wiring, then wrapped the demo in a simple Next.js experience with clear experiment notes.
Technical approach: The project isolates rendering stages and exposes two modes so state changes and shader effects are easier to reason about during debugging.
Outcomes and proof: The two-mode demo is public at GitHub Pages, and the editable TypeScript pipeline code is documented in GitHub.
Limitations: The lab is intentionally narrow and educational, not a production rendering engine.
EthicsFrontEndDemo
Impact: The workshop turns abstract secrets advice into hands-on comparisons that show safer environment-variable workflows in practice.
Built to answer a common beginner question directly: "Why is hardcoding secrets dangerous, and what should I do instead?"
What I learned: Security guidance lands better when people can compare bad and good patterns side-by-side.
More details
My role: I built the interactive tutorial flow, authored scenarios, and mapped each lesson to practical secrets-management principles.
Technical approach: The app uses step-based pages in Next.js + Tailwind with progression cues and side-by-side examples, including references aligned to HashiCorp-style secrets-management pillars.
Outcomes and proof: The public workshop is available at Live Demo and fully documented in GitHub.
Limitations: It teaches foundational patterns and does not replace a full enterprise secrets platform rollout.
CheeseMath Jest tests
Impact: The project preserves utility features while documenting a clear migration path from legacy Jest coverage to a modern Next.js architecture.
Built to prove a utility-heavy app can stay maintainable when rebuilt from legacy React into a modern test-first stack.
What I learned: Rebuilding a legacy app in a modern stack is the fastest way to spot architecture and testability gaps.
More details
My role: I rebuilt the calculator suite, implemented utilities for regex and card validation, and maintained testing coverage while documenting migration decisions.
Technical approach: The current build uses Next.js + Tailwind + NextUI for UI structure and keeps Jest-based verification while documenting planned Vitest/Playwright expansion.
Version comparison:
| Version | Focus | Testing state |
|---|---|---|
| Legacy React app | Original utility workflow baseline | Jest-oriented validation flow |
| Modern Next.js rebuild | Improved component structure + UI delivery | Jest now, Vitest/Playwright planned |
Outcomes and proof: Repo-level test and migration documentation are in GitHub, with a runnable build at Live Demo.
Limitations: Advanced e2e coverage is still in the roadmap and not yet fully implemented.
OBJ parser
Impact: The parser strengthened systems-level reasoning around memory ownership, file I/O paths, and malformed-input handling.
Built to learn Zig by parsing real geometry files instead of reading only toy examples.
What I learned: Manual memory ownership decisions become much clearer when tied to concrete binary parsing tasks.
More details
My role: I designed the parser architecture in Zig, implemented OBJ/MTL reading, defined geometry structures, and added error handling for malformed inputs.
Technical approach: The implementation focuses on explicit memory management and binary-safe parsing paths, with documentation that compares Zig ownership tradeoffs against JavaScript workflows.
Outcomes and proof: Source implementation and README design notes are available in GitHub.
Limitations: This remains an exploratory parser lab and does not yet include a fully optimized rendering pipeline integration.
