How I work

Three things I bring to every project: startup, solopreneur, or scale-up.

Mobile apps

Apps that feel native. Flutter when speed counts, native when polish demands it.

Web platforms

Next.js, Node, Symfony when it fits, architected to grow with you, not against you.

Product thinking

Six years across side-projects and apps at scale. I share what I've learned so you make better decisions, faster.

Stack

The tools I use every day

Filter by category. Click or hover any card to see how I use it.

Services

What I do, end to end

Polyvalent on stack, opinionated on delivery. Six capabilities, always in service of one outcome: shipping something that earns its place in your product.

Product engineering, end to end

From the first sketch to the production deploy: scope, design, build, ship. You stay in the driver's seat the whole way.

Web platforms

Next.js apps, SaaS dashboards, marketing sites. Deployed on Vercel, instrumented with PostHog, transactional emails via Resend. Fast where it counts.

Mobile apps that feel native

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.

AI features that earn their keep

LLM integration, agents, retrieval, evals. With discipline, not hype. I ship the part that moves a real metric and leave out what doesn't.

Analytics & performance

Core Web Vitals, product analytics, funnel debugging, observability. If something's leaking, clicks, retention, latency, I find it and fix it.

Tech advisory

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.

AI Native

Working with AI, every day.

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.
