What I'm looking for

I’m looking to lead engineering and ship AI-powered products end-to-end—architecting full-stack systems, partnering with customers, and using agentic/LLM tooling to accelerate delivery and product decisions.

I’m a Senior Technical Lead and Full-Stack Engineer with 8+ years across product companies and high-growth startups. I’m fluent in writing code, leading teams, and engaging with customers, while staying deeply aware of the AI ecosystem—from agentic workflows to LLM-powered developer tooling.

Most recently, I’ve been embedded as Engineering Lead at a stealth-stage AI cybersecurity startup, leading 30 engineers, onboarding 5 enterprise customers, and translating customer requirements into technical specs and delivery. Earlier at KeyValue, I re-architected a spreadsheet-based analytics platform into a scalable web application (React frontend + Django REST Framework API), migrated a React codebase to TypeScript, and built fintech dashboard features and security with Python-Flask—mentoring engineers and strengthening QA–dev–client collaboration. Before that, at Envestnet, I designed and developed features for a US retirement advisory platform (AngularJS, React, Java, MySQL) and prototyped customer churn using ARIMA/SARIMA/VAR/LSTM models in Python.
