What I'm looking for

I'm looking to build scalable distributed systems and AI-driven products, with opportunities to work on LLM orchestration, agentic workflows, cloud-native platforms, and high-impact backend engineering.

I've built high-throughput backend systems at VERO and Pocket FM, from leasing workflows handling 10,000+ daily applications to microservices serving 50M+ active users with sub-100ms latency.

At VERO, I reduced Redis dependency and saved $2K monthly through an in-memory caching layer, integrated six external platforms with 99.9% reliability, and built background job systems processing 100K+ daily events.

At Pocket FM, I scaled subscription, engagement, and monetization services, built experimentation platforms from 0→1, and delivered notification systems that increased interaction by 35% and retention by 24%.

I'm increasingly focused on Agentic AI, LLM orchestration, RAG, and AI-augmented development. I also built an AI Code Navigator that analyzes repositories, maps dependencies, and generates architecture diagrams.
