Where I add value

Full Stack Development

End-to-end solutions from database design to pixel-perfect UIs. Specializing in React, Angular, and Node.js ecosystems.

Performance Optimization

Building fast, scalable applications that handle millions of users with sub-second load times.

Technical Leadership

Mentoring teams, establishing best practices, and driving architectural decisions for complex projects.

AI-Assisted Development

Building with an AI-native workflow — Claude Code, Cursor, and Codex as daily tools for shipping, reviewing, and testing software faster without cutting corners.

What I'm building

The open-source CMS your agents can actually use. Every publishing action is a typed, permissioned, audited tool — humans get a modern admin, agents get the same 79 tools over MCP. Nobody gets a second-class API.

Hardest problem: making agent and human publishing first-class peers — one permission model, audit log, and review loop shared by the admin UI and MCP, so agents draft and build while humans approve.

The business phone API for vertical SaaS. SMS, voice, voicemail, and real phone numbers through one API — with 10DLC compliance, multi-tenant isolation, and an open-source UI kit.

Hardest problem: multi-tenant number provisioning with 10DLC compliance handled inside the API — designed so both humans and LLM agents can drive messaging and voice workflows programmatically.

Turn a waitlist into a growth engine: viral referral mechanics, templates, and an API-driven platform built with Next.js and Supabase.

Built end-to-end with an AI-native workflow — rapid prototyping to production with Claude Code and Cursor driving iteration speed.
