☁️ Cloud infrastructure that scales without draining your budget, and the full-stack apps that run on top of it. That's the short version of what I do. I'm AWS Certified Solutions Architect Associate and a Certified Kubernetes Administrator (CKA), with 4+ years consulting for international clients on serverless, event-driven, and microservices architectures. I've built real systems, not just diagrams: backend services in Django, NestJS, and Spring Boot; frontends and tooling in TypeScript/JavaScript; SQL and NoSQL data layers; and AWS infrastructure built around services like SQS, SNS, and RDS. My code is clean, documented, and built to be handed off — not just to work today. 🤖 On the AI side, I bring more than surface-level knowledge: a Master's degree in Computer Science (minor in Cybersecurity), and an end-of-studies internship at AUDI working on open-source image-generation models. I put that into practice day-to-day — building AI agents that handle multi-step engineering tasks, wiring automated workflows that chain models, APIs, and tools together, and using agentic AI features to prototype faster and turn early-stage proof-of-concepts into production-ready systems. If part of your project needs AI that actually does work, not just answers questions, that's a space I build in regularly. What you get when we work together: 🧩 Full-stack delivery, start to finish — frontend, backend, database, deployment ☸️ Kubernetes-based container orchestration, backed by CKA certification 🚀 CI/CD pipelines that catch problems before they hit production 🔍Thorough code review — nothing ships without a second pass 🧠Edge cases considered upfront, not discovered by your users ⏱️Systems built around SLAs/SLOs, with zero-downtime maintenance on live environments 💬Communication that doesn't leave you guessing — clear updates, realistic timelines, no surprises Got cloud infrastructure that needs building from the ground up? An existing system that's outgrown its architecture? Or AI agents and workflows you want integrated the right way? That's exactly the kind of problem I like solving. Let's talk about yours.
