I'm a founding engineer and backend lead at duochat.io, where I own backend architecture from system design through production. I built a scalable multi-tenant NestJS and Node.js platform for WhatsApp and omnichannel workflows, helping increase customer engagement by 30%, response rates by 25%, and reduce response time by 20%.

Previously at Pixel Technology, I delivered enterprise data-intensive web applications, including a PepsiCo product data management portal built with Next.js and TypeScript. I've led full-stack delivery, optimized APIs and frontend performance, and worked directly with international stakeholders to turn feedback into maintainable product features.
