I'm a backend engineer who builds real, production-grade systems and integrates AI where it adds measurable value — not a prompt-wiring generalist and not AI-buzzword chasing. I work primarily in Python, Rust, and TypeScript/Node.js, with real production experience in C#/.NET as well. My core backend work: authentication and API layers built with real security discipline (JWT-based auth, proxy-layer rate-limiting, stress-tested at 64 concurrent connections with 99-100% success), event-driven and real-time data pipelines (gRPC feeds, Redis-backed session state), and SQL-based data modeling. I deploy with Docker and CI/CD, and I write regression tests that encode the specific bug being fixed, not just a passing case — so a fixed issue can't silently reappear. On the AI side, I build real infrastructure, not just API calls: I've built and verified my own MCP server from scratch (Python, tree-sitter-based code intelligence for Claude Code, checked against known-correct output before I trusted it), a real-time voice AI agent with genuine barge-in and turn orchestration (LiveKit, Deepgram, Claude, ElevenLabs, load-tested to 100 concurrent sessions), and production Claude API integrations with proper auth and session handling. I've also shipped a complete subscription SaaS product end to end — a .NET/Avalonia Windows desktop app paired with an ASP.NET Core backend and Stripe billing — delivered and 5-star reviewed by the client. I communicate clearly, work in small verifiable increments, and I'm direct about what I've actually built versus what I'd need to learn — I'd rather tell a client the truth upfront than have it surface later. If you need an engineer who combines real backend rigor with genuine AI integration experience, I can help you ship something that actually works.

I don't write code. I engineer products that grow your business. You've got a SaaS or desktop app idea, but the hard parts, multi-tenancy, billing, auth, packaging, auto-updates, are where most projects stall or fall apart. I build production stuff from scratch, and I run several of my own with real paying users. 🛠️ What clients usually hire me for: 🖥️ Desktop Apps (Electron, Tauri) The ones that need signed installers, auto-updates that actually work, and have to behave the same on Windows, macOS, and Linux without weird edge cases. 🕸️ SaaS Platforms from scratch Auth (better-auth or custom JWT), billing (Stripe, Paypal, myfatoorah, Tabby...etc), multi-tenant data isolation done properly, and the admin dashboards nobody wants to build but every founder eventually needs. 🌐 Chrome Extensions MV3, content scripts, background workers, plus the part where you actually get it through Google's review without three rejections. 💬 WebRTC Apps Video, screen sharing, recording, the real-time stuff that works fine in dev and then breaks in production for reasons nobody warned you about. 🤖 AI Integrations OpenAI, Anthropic, MCP servers, RAG, vector search. I run my own MCP hosting platform, so I've already hit most of the rough edges and have opinions on them. 🧑‍💻 My usual stack: ✅ Frontend: Next.js, Nuxt or Elixir ✅ Backend: Golang, Python or Node.js ✅ Databases: PostgreSQL, Redis, ClickHouse where it earns its keep ✅ Deployment: Docker, SSH ✅ AWS, Google Cloud, Hetzner, Cloudflare for CDN, DNS, and Workers If your project is already on something different and it's reasonable, I'll work in that. The thing that probably matters more: I developed real products with real users, so when you describe a problem you're hitting, I've probably already hit a version of it and know what the cheap fix is versus the right fix. 📩 Tell me what you're building. I'll get back to you in 1 to 3 hours with the questions I think actually matter, the ones about the parts that usually get skipped until they blow up later.

I build production-grade backend systems and AI-driven automation tools — from GoHighLevel marketplace apps to AI agents that take real actions across Slack, HubSpot, and Gmail. Over the past several years, I've delivered systems that go beyond CRUD APIs: async architectures, OAuth-secured integrations, and AI agents that don't just chat — they execute (creating CRM deals, triggering workflows, running background jobs) with human-in-the-loop oversight for sensitive actions. ✔️ Backend: Python, Django, Django REST Framework, FastAPI, Flask, PostgreSQL, Redis, Celery, async task queues ✔️ Frontend: React.js, Next.js, TypeScript, Redux Toolkit, HTML5/CSS3 ✔️ Cloud & DevOps: Docker, Kubernetes (GKE), AWS, Google Cloud Platform, CI/CD (GitHub Actions), Prometheus monitoring ✔️ Automation & Integrations: GoHighLevel (GHL) app development, n8n, OAuth flows (HubSpot, Slack, Google), webhooks, Stripe 🏆 Highlighted Work ✔️ GoHighLevel Marketplace App Built a custom GHL app installable directly from the GHL App Store — in-app onboarding, secure payment credential collection (Stripe), and a fully white-labeled booking application deployable to each customer's own GHL domain with custom branding. ✔️ AI-Powered Support Agent (FastAPI) Built and maintained a FastAPI backend for an AI agent handling live conversations across Slack, Gmail, and web chat — with async webhook processing, OAuth token handling, and AI-driven actions (e.g., auto-creating HubSpot deals) run as non-blocking background tasks. Added WebSocket-based human-in-the-loop review so sensitive actions get a timed admin check before executing. ✔️ B2B Lead Data Platform Django-powered platform structuring verified B2B lead and technographic data for sales/marketing teams — RBAC, bulk CSV import, Stripe monetization, async processing via Celery, deployed on GKE with GitHub Actions CI/CD. 🎯 What I Can Help You Build - GoHighLevel apps, funnels, and white-labeled sub-account tools - AI agents/chatbots that take real actions, not just answer questions - FastAPI/Django backends with async processing and third-party integrations - Kubernetes/Docker deployments on GCP or AWS - n8n and webhook-based automation between your existing tools I focus on clean architecture and systems that keep running with minimal oversight — not just shipped features. If you need someone who can own the backend, wire up AI automation, and deploy it reliably, let's talk. Keywords: Python Developer, Django Developer, FastAPI Developer, GoHighLevel Developer, GHL App Development, AI Agent Developer, AI Automation, Chatbot Development, Kubernetes, Docker, AWS, Google Cloud Platform, React, Next.js, REST API, OAuth Integration, Webhook Automation, n8n, Celery, PostgreSQL, Redis
