ABOUT ME
Lead full-stack JS developer with 9+ years of experience (previously at Thoughtworks)
Lead full-stack JS developer with 9+ years of experience (previously at Thoughtworks)

Software engineer, consultant, and technical lead with 11+ years of experience building products across banking, fintech, enterprise software, and AI.

I've spent my career working in very different environments - from Oracle Financial Services, to consulting at Thoughtworks, to early-stage startups - while helping teams turn ambiguous business problems into production systems.

My technical background spans full-stack development, distributed systems, cloud infrastructure, and AI-powered applications. I've worked with React, Angular, Go, Python, Java, .NET, Kubernetes, AWS, and Azure.

Currently, I'm a Senior Software Engineer at Blackcurrant, where I help build AI-powered products for the energy industry. My work spans architecture, product development, automation, stakeholder collaboration, hiring, and delivery.

Previously at Thoughtworks, I led development efforts for banking platforms serving millions of customers, working closely with architects, program managers, engineers, and business stakeholders. Much of my time was spent bridging the gap between technical implementation and business objectives. I have helped take multiple products to market.
