🤝 How I Work

I help founders and product teams launch MVPs, extend existing applications, and take over codebases that need an experienced developer. I can own the technical work from architecture through testing and release.

I use a modern, AI-assisted development workflow with Claude Code and Codex, supported by automated testing and CI/CD. I review AI-generated code, make the technical decisions, and take responsibility for what ships.

Web application and SaaS development

My full-stack development work includes customer portals, dashboards, admin panels, and subscription products. I connect React, Next.js, or Angular interfaces with Node.js APIs and PostgreSQL databases, including authentication, permissions, onboarding, and billing. For an existing SaaS platform, I can add features or take responsibility for ongoing development.

Front-end development with React, Next.js, and Angular

I build responsive interfaces in TypeScript and JavaScript, working with HTML and CSS to make complex forms, data tables, and dashboards usable across screen sizes. I also improve existing React and Angular applications through UI polish, performance fixes, and clearer user flows.

Backend development and API integration

I develop Node.js and NestJS backends, Python/FastAPI services, and PostgreSQL databases. API integration work includes Stripe subscriptions, external business services, and connections between frontend applications and REST or GraphQL APIs. I also work with Supabase when it fits the product.

Electron desktop application development

I build Windows and macOS applications with React or Angular interfaces. My Electron work includes native desktop recording, offline workflows, code signing, Apple notarization, automatic updates, and packaging. I also take over existing desktop applications to fix performance issues and prepare releases.

AI app development and code review

I integrate the OpenAI API into web applications and build features such as document extraction and workflow automation. For inherited codebases and AI-built prototypes, I review access controls, data handling, and the workflows that need attention before planning the next development milestone.
