Summary
Principal-level Backend Software Engineer with 14 years of experience building backend systems, APIs, and distributed applications. I’ve worked across different industries, designing systems that need to scale, stay reliable in production, and remain maintainable as they grow. My background is strongest in backend architecture, API design, and distributed systems, and I’m comfortable leading technical decisions, mentoring engineers, and working closely with product and engineering teams.
