I help startups build web products end to end: Angular on the frontend, Go and PostgreSQL behind it. If your SaaS app, dashboard, or admin panel is getting harder to change, I can work on both sides of the problem: the UI your users touch and the API and data it depends on. One person owning a feature from the database to the screen means fewer handoffs and fewer "the backend doesn't return that" surprises. What I usually help with: - Angular architecture, refactoring, and strict TypeScript cleanup - RxJS state management, memory leak fixes, and performance on data-heavy screens - Go APIs and services backed by PostgreSQL or MongoDB - Docker setups and CI/CD pipelines - Playwright tests for critical flows like auth, onboarding, forms, billing, and admin actions I'm most useful when you need someone who can ship features, spot technical risk early, and keep the codebase from turning into a bottleneck as the product grows. I've worked on large production codebases, including the TrueNAS WebUI, and I'm comfortable joining existing teams, working in messy real-world code, and improving things without pushing for a rewrite. If you need a senior developer who can move your product forward on both frontend and backend without piling up avoidable tech debt, I'm a good fit.
