Omer K.

Full-Stack Python & Next.js Engineer | AWS & GCP Cloud Developer | Automation, Integrations & Data Engineering | Client-Facing Experience with Global Teams I build, scale, and rescue production systems for SaaS products, AI applications, and teams outgrowing their current infrastructure. Most engineers can ship features. I build systems that hold up under real load and fix the ones that don't. Where I help: Slow, breaking, or unreliable backend systems Scaling problems and messy cloud infrastructure AI and RAG systems that need to run reliably in production Complex integrations with APIs, payments, data pipelines, hardware Migrations between cloud providers without downtime Recent work: Architected and migrated production infrastructure across AWS, GCP, and DigitalOcean Built a RAG-based internal tool that lifted a 30-person team's productivity by 22.5% Hosted and migrated a 10TB+ dataset with zero data loss Designed distributed multi-region processing systems handling concurrent workloads Built a SaaS platform doing $10K+ monthly recurring revenue Shipped 5+ CI/CD pipelines for teams that previously deployed by hand Stack: Cloud: AWS, GCP, DigitalOcean, Contabo, Cloudflare Backend: Python (FastAPI, Flask, Django), Celery, Docker, Redis Data: PostgreSQL, MongoDB, Supabase, GraphQL, vector databases AI: RAG pipelines, LangChain, LlamaIndex, OpenAI/Anthropic, Ollama How I work: I take ownership of outcomes, not just tickets. You get clear technical direction, structured execution, and a system that's still working six months later. Send me a message with what you're building or what's breaking. I'll reply with a technical approach and the fastest path to a stable solution.
