Guy Romelle Magayano

I’m a Senior Software Engineer with 11+ years of experience building production web platforms across e-commerce, SaaS, media, and internal tooling. My background is full stack with a backend-heavy center of gravity, and I’m strongest when I can own work end to end across APIs, data, frontend delivery, integrations, testing, and release quality. In recent roles, I’ve improved support workload by 35-55% by stabilizing payment and event-driven workflows with retries, replay tooling, and reconciliation. I’ve delivered storefront flows across 35+ markets, improved validation and pricing reliability in revenue-critical funnels, and driven performance gains such as 8-12 point Lighthouse improvements and 15-25% LCP reductions. I’ve also worked on multi-tenant analytics platforms, admin-heavy workflows, publishing systems, and CI/CD improvements that reduced release overhead and made delivery more predictable. My core stack includes TypeScript, JavaScript, Python, React, Next.js, Node.js, Django, SQL, PostgreSQL, and modern testing and CI/CD practices. I’m comfortable working across product, design, and engineering, and I do best on teams that value pragmatism, reliability, and clear technical judgment over hype. I’m looking for a remote senior software engineer role at a product-focused company where I can contribute strong end-to-end ownership, practical architecture and delivery judgment, and steady execution in an async-friendly environment.
