About
I’m a Senior Staff Software Engineer with 10+ years of experience designing and delivering scalable distributed systems, microservices, and enterprise web platforms. I stay hands-on across production code, system design, critical debugging, and operational excellence—bridging architecture decisions with measurable performance and reliability improvements.
Over the years I’ve led cross-functional engineering efforts for remote teams, shaping solutions with Python, TypeScript/JavaScript, and backend frameworks like Django, FastAPI, and Nest.js, with PostgreSQL at the core of many high-throughput systems. I also integrate AI-driven capabilities using OpenAI and LangChain (including RAG and embeddings/vector search patterns), and I’m comfortable owning CI/CD, observability, and delivery workflows end-to-end.

Work experience· 5 roles
Led the architectural overhaul and delivery of multi-platform ecosystems, optimizing secure deployments with Docker and Fly.io. Architected microservices using Django/Python and PostgreSQL, improving schema performance, database concurrency, and maintainable data flows. Drove production operations, code and design reviews, observability templates, and scalable engineering practices. Integrated OpenAI APIs with custom LangChain wrappers to power context-aware AI assistant engines and verification layers. Built a modern front end using React.js, TypeScript, Refine.dev, and MUI, separating admin workflows from headless CMS-driven experiences. Implemented Docker- and GitHub Actions-based CI/CD to increase deployment velocity and reduce staging validation discrepancies.

Architected microservices with Django, Python, and PostgreSQL, improving schema performance, database concurrency, and data maintainability. Drove production operations through code and design reviews and established observability templates. Integrated OpenAI APIs with custom LangChain wrappers to power context-aware AI assistant engines with data verification layers. Built a modern web platform using React.js, TypeScript, Refine.dev, and MUI, separating administrative workflows from headless CMS-driven experiences. Implemented CI/CD pipelines with Docker and GitHub Actions to increase deployment velocity and reduce staging validation discrepancies.
Architected high-volume distributed web systems for global telecommunications clients using Nest.js, Next.js, and React to reduce server-side load times. Engineered responsive backend REST APIs and data querying mechanisms with Django and Python, connecting decoupled microservices. Guided technical decisions on state management and indexing strategies using GraphQL (Apollo), Redux, and Firebase real-time infrastructure. Built AI pipelines combining Azure OpenAI, LangChain, and Pinecone vector databases to deliver conversational business intelligence. Established rigorous testing practices with Jest and Enzyme to reduce runtime regressions and improve production stability.
