Modern interfaces
Next.js, React, TypeScript, responsive UI, accessibility, design systems, and motion.
Full Stack Developer / AI-capable product engineer
Hi, I am
Valter Ussene
Building complete products from interface to infrastructure.
I design and ship production web platforms with Next.js, React, Go, Python, PostgreSQL, Docker, and Azure. AI/ML is part of the toolkit, not the whole story.
About me
A product-minded engineer across the whole stack.
I build the visible product and the systems behind it: interfaces, APIs, data models, integrations, deployment workflows, and applied AI features when they create real value.
APIs and services
Go, FastAPI, REST, GraphQL, authentication, third-party integrations, and background workflows.
Production foundations
PostgreSQL, Redis, Docker, Azure Static Apps, Container Apps, storage, and CI/CD.
Useful intelligence
Audio models, voice interfaces, Twilio, STT/TTS, Python ML pipelines, and inference APIs.
What I optimize for
- Clear product flows backed by dependable APIs.
- Maintainable code, predictable deployments, and practical testing.
- AI features that solve a product problem instead of becoming the product itself.
Delivery profile
Every layer gets the same level of care, from clean TypeScript components to Go services, database models, deployment automation, and production-ready AI workflows.
Featured work
Selected projects.
Five shipped pieces that show the full range: commerce, education, restaurant experiences, cloud backends, and applied AI.
