What I'm looking for

I want to build AI-adjacent, agent-like workflow automation and real-time decision systems. I’m excited by roles where I can define architecture, lead delivery end-to-end, and ship production-grade React/Python/Node solutions in cloud environments.

I’m a Senior Software Engineer with 13+ years of experience designing and delivering large-scale full-stack systems, AI-adjacent platforms, and distributed architectures. I focus on building real-time, data-driven products and workflow automation that simplify complex operations.

In my most recent role, I led the development of AI-adjacent enterprise platforms using Python (FastAPI, Django) and React/Next.js. I built full-stack systems supporting 85,000+ active users, designed API + frontend workflows for complex data-driven operations, and delivered real-time dashboards for monitoring and visualization.

I also work deeply at the systems layer—building event-driven backend components with Kafka and Redis Streams, designing scalable microservices, and optimizing database performance. I’ve improved PostgreSQL query performance by +38% on large datasets and introduced test automation (PyTest + Jest) to strengthen stability and reliability.

Across enterprise cloud environments, I’ve defined architecture, led engineering teams (7–9 engineers), and delivered production-grade CI/CD and monitoring. I’m especially passionate about intelligent, agent-like systems, LLM-adjacent integration patterns, and highly interactive frontends that keep operations fast, observable, and dependable.
