How I work
Apps that feel native. Flutter when speed counts, native when polish demands it.
Next.js, Node, Symfony when it fits, architected to grow with you, not against you.
Six years across side-projects and apps at scale. I share what I've learned so you make better decisions, faster.
Stack
Filter by category. Click or hover any card to see how I use it.
Services
Polyvalent on stack, opinionated on delivery. Six capabilities, always in service of one outcome: shipping something that earns its place in your product.
From the first sketch to the production deploy: scope, design, build, ship. You stay in the driver's seat the whole way.
Next.js apps, SaaS dashboards, marketing sites. Deployed on Vercel, instrumented with PostHog, transactional emails via Resend. Fast where it counts.
Flutter when speed matters, native when polish does. I pick the right tool, not the trendy one, and ship cleanly to the App Store and Play Store.
LLM integration, agents, retrieval, evals. With discipline, not hype. I ship the part that moves a real metric and leave out what doesn't.
Core Web Vitals, product analytics, funnel debugging, observability. If something's leaking, clicks, retention, latency, I find it and fix it.
Stack decisions, architecture reviews, founding-engineer support. I'll tell you when not to build it. I'll help you hire after.
Don't see your exact need? Most projects bend across two or three of these.
Let's talk →AI Native
AI is part of how I build now. Pairing with Claude through Claude Code helps me move quicker and catch more on review. I read everything that goes out, and I try to stay honest about where it helps and where it doesn't.
Quicker iterations
Spec → prototype → review → ship in days. Less guesswork, more back-and-forth with you.
Extra pair of eyes
AI-assisted refactors and reviews help me catch things I'd miss on my own. Not perfect, but useful.
Read by a human
AI gets things wrong. I read what it writes, ask questions, and take responsibility for what ships.
