Founding Engineer, Technical Lead and Full-Stack Developer with 15+ years of experience, the last 10 working remotely with U.S.-based teams. At startups I have taken full product ownership end-to-end: gathering requirements with stakeholders, designing backend services and third-party integrations, building the UI, and automating deployments.
What I bring
- Frontend: React, Angular, TypeScript
- Backend: Python (FastAPI, Django), Node.js (NestJS, Express), .NET Core
- Cloud & DevOps: AWS, GCP, Azure, Docker, Kubernetes, Terraform, CI/CD
- Data: PostgreSQL, SQL Server, MongoDB, BigQuery, Airflow
- Event-driven architectures: Apache Kafka, RabbitMQ, AWS SQS/SNS/EventBridge
- AI: LLM-powered features and agentic workflows (LangGraph, Claude, OpenAI)
I have worked across Fintech, Healthtech, Legaltech, Cleantech, Retail, SaaS and Insurance, in both large enterprises and startups (Flatiron Health, PowerFlex, mParticle, Betterfly, among others), always with a keen eye on business value. I automate at every level (CI/CD, unit/integration/E2E testing, monitoring) and enjoy mentoring developers.
I'm looking for remote Senior / Lead / Founding Engineer roles where I can own products end-to-end, especially around AI-powered features and scalable backend systems.
