Full-Stack Developer with 3 years shipping production web applications end-to-end — React/TypeScript frontends, REST API backends, relational databases, and Docker-based deployment — plus deep experience building AI automation pipelines on top of that stack. Founder of AgentDevX, an MCP-native agent infrastructure platform built and shipped solo from architecture through production billing. Comfortable owning a feature from database schema to deployed UI, working closely with co-founders, clients, and cross-functional stakeholders across remote, fast-moving teams.
- Architected and shipped a full-stack agent-infrastructure platform end-to-end: PostgreSQL (Supabase) schema design, Hono/Bun REST API backend, Ed25519 cryptographic identity layer, AES-256-GCM encrypted credential vault, and OPA WASM policy engine.
- Built and containerized backend services with Docker; deployed to Render/Railway with tiered subscription billing ($8–$29/mo) via Lemon Squeezy.
- Designed MCP-native API endpoints with dry-run mode, per-agent memory, and capability tagging, collaborating directly with a co-founder on product scope and go-to-market positioning.
- Built a 16-node n8n B2B lead-generation workflow for agency founders and SaaS decision-makers, using Supabase/PostgreSQL for deduplication and logging.
- Developed a full-stack voice AI receptionist (OpenAI Speech API + JavaScript front end) for a live client-facing portfolio site, handling recruiter queries and contact capture end-to-end.
- Delivered cinematic, full-stack landing pages (AURUM, POPI Watch, OBSCURA) using React-adjacent tooling, Three.js, and GSAP ScrollTrigger, working directly with clients on requirements and revisions.
- Automated a video production pipeline (Python → Remotion → ElevenLabs) for recurring YouTube content delivery.
- Designed and developed the company's front-end architecture, ensuring a responsive, fully optimized UI across devices.
- Owned daily site maintenance, technical checks, and bug troubleshooting in coordination with internal stakeholders, maintaining zero downtime.
- Implemented performance improvements that reduced page load time and improved overall user experience.
- Built and maintained full-stack front-end and backend architecture for the company's e-commerce website.
