Grouped by how I use them in production — core languages, frontend, backend, data, AI, and cloud.
I'm a Senior Full-Stack Engineer with 5+ years of experience building production applications across PropTech, FinTech, GIS, eCommerce, HealthTech and AI-powered SaaS.
My strongest engineering experience is in Angular, Node.js and TypeScript, with hands-on experience across React/Next.js, MongoDB, PostgreSQL, Redis, microservices, cloud infrastructure and AI integrations.
I enjoy solving difficult engineering problems involving performance, scalability, APIs, distributed workflows, security, and maintainable architecture.
I help startups and businesses ship production software — Angular and Node.js applications, SaaS platforms, payments, AI features, and cloud deployment. You get a senior engineer, not a ticket-taker.
Angular-first frontends with Node.js / NestJS APIs, ready for real users.
Roles, dashboards, subscriptions, and workflows that match how you sell.
Stripe, PayPal, maps, auth, and the third-party APIs your product depends on.
LLM features, RAG, and chat that sit on your data — not a demo chatbot.
From MVP to production: auth, APIs, admin panels, and deployment.
Faster APIs, Redis, Docker, AWS, and CI/CD so the app stays up after launch.
I'm open to Senior Full-Stack, Senior Node.js, Senior Angular, Backend Engineering, and AI-focused engineering opportunities.
