What I'm looking for

I’m seeking a senior backend/full-stack role in fintech or healthtech where I can lead projects, design secure scalable systems with Python/Django, and work in an agile team focused on quality, integrations, and technical mentorship.

I’m a Senior Software Engineer with 15+ years of experience building backend and full-stack systems, with a strong focus on Python, Django, PostgreSQL, APIs, integrations, and distributed systems. My recent work also includes TypeScript, NestJS, AWS, asynchronous processing, authentication, observability, and production reliability.

I have worked extensively in healthcare and fintech, including FHIR R4, OMOP, Athenahealth, Healthie, REST and GraphQL integrations, OAuth/OIDC, JWT, PostgreSQL optimization, and AWS-based infrastructure. I’m comfortable owning features end to end, from technical design and implementation through testing, deployment, monitoring, and production support.

I also have experience leading small teams, working directly with clients and stakeholders, reviewing code, mentoring engineers, and contributing to product and architectural decisions. I value pragmatic engineering, clear communication, automated testing, and building maintainable systems that solve real business problems.
