What I'm looking for

I want to lead end-to-end engineering—building real-time, scalable platforms and applying AI (RAG) to automate sensitive, high-compliance workflows. I’m happiest with strong architecture ownership, fast execution, and measurable system performance.

I’m a Lead Software Engineer who drives end-to-end SDLC and architecture, translating product vision into reliable, high-performance systems. At Fosmith, I led the launch of “ListenNeat” with a custom, highly-optimized audio engine and a Kotlin/Django backend.

I specialize in distributed, real-time infrastructure—architecting a highly available cloud stack (DigitalOcean, Redis, PostgreSQL, Nginx) supporting 3,000+ concurrent WebSockets with sub-second message latency. I also directed a 4-engineer Java-to-Kotlin mobile migration and Django refactoring, tightening standards with strict server-side encryption.

As an independent consultant, I build production AI that meets compliance needs, including a Python + Google Gemini RAG chatbot for sensitive medical waste protocols. I’ve implemented high-precision retrieval with NumPy embeddings to reduce hallucinations, containerized secure backends (Docker, PostgreSQL, Redis), and delivered real-time analytics dashboards—while also shipping full-stack geospatial tracking and integrations like NetBox and Google Maps.
