What I'm looking for

I’m looking for a role where I can own end-to-end delivery of complex distributed systems, improve reliability and performance, and apply practical AI automation—working with teams that value engineering rigor and shipping to production.

I’m a Senior Software Engineer with 8+ years of experience designing and scaling distributed systems that power high-impact products. I lead complex projects from concept to production, owning the full lifecycle and consistently improving reliability, performance, and user experience at scale.

Recently, I’ve shipped Docker/Kubernetes-backed projects end-to-end, built real-time device management for resource-constrained IoT, and developed RAG pipelines with fine-tuning plus AI agents and automation workflows using langgraph, pydantic ai, llms, and n8n. Earlier roles strengthened my backend and systems foundation—PKI security deployment for IoT/OT, microservices on high-availability clusters, and scaling cloud telephony to 50k concurrent calls—while my fintech background helped me deliver PCI-compliant payment experiences from backend to live integrations.
