Senior Backend and AI Engineer with 5 years building and scaling distributed systems. I've owned core backend services for a real-money gaming platform at 5M+ MAU, run production end-to-end as a sole engineer and founding tech lead, and now build agentic AI systems on Google ADK at T-Systems (Deutsche Telekom), embedded with a distributed European engineering team.

I care about systems that stay correct under load — zero-fault wallets, fault-tolerant game state, and clean delivery pipelines.

Building the backend for an internal AI workflow platform at T-Systems:

• A Google ADK layer running 10+ production agents — RAG chatbot over internal docs, document-extraction pipelines, a graph agent that visualizes live DB relationships, and task-specific subagents bound to internal tools
• JWT auth, persistent chat-history store, and performance-tuned REST APIs
• HTTP streaming contracts with the data science team, plus cloud deployments and CI/CD

🤖 AI Workflow Platform — T-Systems (Deutsche Telekom) Backend + Google ADK layer powering 10+ production agents, including a RAG chatbot over internal docs and a live DB-relationship graph agent.

🎮 Real-Money Gaming Platform — Gridlogic Owned game-engine logic and core services (auth, sessions, wallet engine) at 5M–10M MAU, handling 1K–10K req/sec at peak on FastAPI, RabbitMQ, Redis, and PostgreSQL with a zero-fault bar. Cut mid-game error rates ~30% by tracing millions of distributed events.

🏗️ CRM & CMS Platform — Stride Ahead (Founding Engineer) Built greenfield from zero to 15K–20K MAU at 99.9%+ uptime — assessment engine, automated PDF pipeline (1,000+ reports/month), and a recommendation loop, scaled across 10+ servers. Returned as Tech Lead to cut release cycles from ~4 hours to under 15 minutes.

📱 Product Builds — BizAssist (Freelance Tech Lead) Shipped four production web apps solo (Next.js, Node.js, MongoDB) with zero post-launch P0s over 12 months, including a React Native booking app that cut booking overhead ~60%.
