What I'm looking for

I want to lead a product-focused engineering team where I can own architecture end-to-end, scale teams responsibly, and modernize AWS/Azure systems—using AI-augmented workflows, strong mentoring, and measurable performance and cost wins.

I’m a Tech Lead with 10+ years of experience building and scaling SaaS products and engineering teams. I’ve owned end-to-end platforms—driving architecture, system design, and AWS infrastructure—while mentoring engineers and sharpening delivery execution.

At Polly, I scaled the team from 3 to 10 engineers and led an AWS infrastructure refactor that improved performance by 60% and reduced cloud costs by 60%. I also optimized MongoDB queries and implemented a Kafka-based messaging system to strengthen data flow, and I led Polly Quizzes, directly contributing to new sales and enterprise deal closures.

I bring a practical, AI-augmented engineering mindset, leveraging agentic coding tools (Cursor, Claude Code) across planning, development, code review, DevOps, and automation workflows. Previously at APIMatic, I led a hybrid Web & DevOps team, reduced Azure cloud costs by 50%, delivered .NET/React DX products, and helped close enterprise deals contributing $200K to ARR while increasing sprint velocity by 30% through streamlined Agile practices.
