Selected Projects
A local-first, installable training PWA with no backend — a typed 26-week gym-and-running programme, set-by-set logging, nutrition tracking, and an insights dashboard whose every number is computed by pure, tested functions. Data lives in IndexedDB, works fully offline, backs itself up to a user-chosen folder, and ships through small, CI-gated pull requests.
React · TypeScript · Vite · PWA · IndexedDB · Dexie
An offline-first Android file explorer, viewer, and editor built directly on the Storage Access Framework — pluggable format handlers, multi-file tabs, biometric app lock, and an entirely opt-in, bring-your-own-key AI layer (chat, inline rewrite actions with a real diff review, and SQLite-FTS5 folder search) that never breaks the no-cloud-by-default promise.
React Native · Expo · TypeScript · Android · SQLite · FTS5
A zero-trust guardrail gateway and red-team evaluation harness for LLM applications — a two-tier adversarial detection pipeline (deterministic rules + an escalated LLM judge) plus a 127-case hand-authored attack corpus that measures whether the defense actually holds.
TypeScript · Next.js · LLM Security · Prompt Injection · Groq · Google Gemini
A self-hosted, multi-camera, multi-user security camera platform — Next.js + MediaMTX + ffmpeg, WebRTC/HLS streaming behind auth, reachable from anywhere over a private Tailscale network instead of any cloud service.
Next.js · TypeScript · MediaMTX · WebRTC · ffmpeg · Tailscale
A premium full-stack portfolio built as a 3-app monorepo — public site, REST API backend, and a private admin dashboard.
React · TypeScript · Node.js · MongoDB · Framer Motion · GSAP
A glass-box medical claims adjudication and fraud-defense platform — an AI agent pipeline turns unstructured claim documents into explainable, role-specific decisions for patients, hospitals, and insurers.

Next.js · React · TypeScript · FastAPI · Python · Gemini
An AI-powered financial intelligence platform — parallel agents deliver probabilistic revenue forecasts, buy/sell signals, and peer benchmarks in under 20 seconds.
Python · FastAPI · React · Scikit-learn · SHAP · Groq LLaMA
An AI platform that converts unstructured project data — Slack threads, emails, meeting notes — into validated BRD drafts automatically.
Next.js 14 · FastAPI · Python · Groq LLM · PostgreSQL · Firebase
A production-style Retrieval-Augmented Generation system — documents are chunked, embedded with SentenceTransformers, indexed in Endee's HNSW vector database, and retrieved via cosine-similarity k-NN search to ground Groq's Llama 3.3 70B in a user-provided knowledge base with full source attribution.
