Wilton Pelicari

Senior Full Stack Developer

Profile

Full stack developer since 2014, working mostly in C#/.NET and TypeScript, from enterprise systems in Brazil to SaaS platforms in Canada. At Sherweb I build distributed .NET services and React front ends that run on Kubernetes, working spec-first with AI-assisted tooling. On my own time I design, build and publish mobile apps end to end; three are live in the stores today.
