What I Can Build for You

Each engagement is tailored to your specific needs — no cookie-cutter templates.

Full-Stack Web MVP

Next.js · React · Node.js · PostgreSQL

From idea to deployed product. I build production-ready full-stack web applications with clean architecture, fast performance, and SEO built-in from day one.

  • PostgreSQL / Supabase / MongoDB database
  • Auth, Payments, and 3rd-party API integration
  • Vercel / Railway deployment + CI/CD

AI Agent Development

LLM · Tool Calling · RAG · Streaming

Custom autonomous AI agents that think, plan, and act. I integrate LLMs into your product with streaming UI, tool calling, RAG pipelines, and robust fallback logic.

  • Custom AI agents (Gemini / GPT / Groq)
  • RAG pipelines with vector search
  • Streaming real-time UI (SSE / WebSocket)
  • AI workflow automation & scheduling
  • Multi-provider fallback for 99.9% uptime

API & Automation

REST · Webhooks · Cron Jobs · Integrations

Connect your existing tools, automate repetitive workflows, and build reliable data pipelines. No more manual busywork.

  • REST API design & development
  • Webhook integrations (Stripe, Resend, Telegram, etc.)
  • Scheduled jobs & cron automation
  • Data scraping, parsing & transformation
  • Third-party SaaS API integration

Technical Consulting

Architecture · Code Review · SEO · Performance

Need a second pair of expert eyes? I audit your codebase, optimize performance, fix SEO issues, and advise on architecture decisions.

  • Architecture review & recommendations
  • Core Web Vitals & performance audit
  • SEO + GEO (AI crawler optimization) audit
  • Code review & refactoring guidance
  • Tech stack selection & roadmap planning
