Healthcare HL7 Integration Platform (under NDA)

Production full-stack work on a commercial HL7 healthcare integration engine at TransData (Jan–Mar 2026), where I was the top contributor (~248 commits). Product name withheld under NDA. Built a React 19 + TypeScript + Vite frontend and a Node.js + TypeScript Express-style BFF (Sequelize, Jest) proxying the platform's server API. Delivered PHI-access auditing features, real-time message-trends dashboards, and accessibility work (ARIA, focus management, keyboard navigation). Operations tooling for healthcare integration teams — scope and ownership stated plainly; no clinical-software or compliance-ownership claims.

HireTrack — AI Résumé Builder & Job Pipeline Tracker

Open-source, bring-your-own-key web app that tailors ATS-ready résumés to each job and tracks an interview pipeline — the tool I use to run my own job search. A deterministic-first LangGraph pipeline extracts job-description data and scores match/positioning; résumés export to ATS-safe DOCX, PDF, or Markdown entirely client-side. Truth-only tailoring mirrors JD phrasing with no invented skills or metrics, and every run appends honesty/verification notes. Supports 5 AI providers (Anthropic, OpenAI, Gemini, and any OpenAI-compatible endpoint), Supabase Postgres + Auth with row-level security, and installs as an offline-first PWA.

AI-Powered LinkedIn Content Platform

Primary DRF backend developer for a production AI-powered LinkedIn content platform. Built 7 backend services and 60+ REST endpoints, including versioned prompt management across AI content pipelines (n8n), multi-tier profile extraction (LinkedIn API → scraper → OpenAI fallback), real-time notifications via Django Channels WebSockets, Stripe-based subscription billing, OAuth2 + JWT refresh auth, and semantic search using Gemini embeddings + pgvector with Redis caching.

AI-Driven Cryptocurrency Intelligence Platform

Architected a real-time intelligence backend as sole engineer, ingesting social data from Telegram, Discord, and X and processing it with Google Gemini embeddings and pgvector semantic search. Built async multi-chain blockchain analysis services with token-bucket rate limiting and Redis caching, plus ML-based DEX scam-token detection. Orchestrated ~10 services via Docker Compose with migrations, background workers, and structured logging.

Enterprise HRMS Migration & Automation

Migrated and extended a Django-based HRMS (Horilla) for a ~200-employee workforce with full backend ownership. Built attendance, contract, and reporting modules, implemented ZKTeco biometric sync via Web API, designed a multi-device biometric schema, and built monthly/day worksheet reporting endpoints. Deployed a Dockerized system on DigitalOcean with Nginx, Celery background jobs, structured logging, and zero-downtime rolling deploys.

ERPNext / Frappe Customization & Internal Tooling

Customized ERPNext / Frappe v16 with custom doctypes, server scripts, client scripts, and page-level UI — including an Asana-style task-tree view for internal task management. Used the bench CLI and REST APIs for programmatic data management and bulk fixes, and researched ERPNext authentication/SSO options for integrating a custom Parts-Intelligence dashboard with ERP-backed access. Worked through role/permission, private-file, and reverse-proxy/WebSocket production concerns.
