Full-Stack Engineer (Backend-Leaning)
Backend depth with shipped React/TypeScript front-ends and product workflows.
Why hire me as Full-Stack Engineer?
I'm a backend-leaning full-stack engineer: strong on APIs, data, and infrastructure, with real production front-end work. I've shipped React/TypeScript for clients at TransData, built this Astro + React portfolio, and designed and built HireTrack end to end — React 19, Supabase (Auth + RLS), a LangGraph pipeline, client-side document tooling, and a PWA. I can own a feature from schema to UI.
What I've shipped
- Designed and built HireTrack end to end — React 19 front-end, Supabase Auth + row-level security, LangGraph pipeline, and PWA
- Shipped production React/TypeScript front-end work for clients at TransData
- Built full-stack AI prompt-management tooling (Django/FastAPI backend, streaming UI, RBAC, S3)
- Customized ERPNext/Frappe with page-level UI and backend scripts for internal task-management workflows
- Built this portfolio on Astro + React with SEO/GEO, role-targeted pages, and CI/CD to GitHub Pages

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.
- 5 AI providers (BYOK)
- LangGraph JD pipeline
- ATS-safe DOCX/PDF export

AI Prompt Management Platform
Full-stack Django/FastAPI platform integrating OpenAI GPT-4 with streaming responses for prompt versioning, with modules for prompt templates, function helpers, and task planning.

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.
- Custom doctypes + scripts
- Asana-style task tree
- bench CLI + REST automation
