Hi, I'm
Valter Ussene
Building voice-enabled applications with Twilio, TTS and STT integration, and CRM systems. Specializing in full-stack development with Go, React, PostgreSQL, and cloud-native architectures on Azure.
About Me
Building cognitive products that feel delightful, dependable, and deeply intelligent.
I blend machine learning research with battle-tested software craftsmanship. From architecting multi-cloud data platforms to launching immersive web experiences, I thrive on shipping systems where inference, automation, and human insight work in harmony. My stack of choice pairs Go + FastAPI backends with modern Next.js frontends, all instrumented with observability, CI/CD, and security by default.
Machine Learning & Audio Processing
Building emotion recognition systems with Wav2Vec2, achieving 97.6% accuracy. Integrating TTS/STT solutions with Twilio for voice applications.
End-to-end Product Delivery
Architecting platforms with Go, PostgreSQL, Redis, and GraphQL backends paired with React/Next.js frontends. CI/CD pipelines on Azure.
Azure & DevOps
Deploying containerized applications with Docker, Azure Container Apps, and Static Web Apps. Building scalable cloud-native solutions.
What drives me
Translate research-grade models into robust APIs with clear SLAs and rock-solid monitoring.
Design human-centered experiences that make complex data feel intuitive and actionable.
Mentor teams to ship faster with automation, testing, and platform thinking as first principles.

I obsess over the craft: from clean abstractions in Go and TypeScript to resilient data pipelines in Python, every layer gets the same level of care. Whether it’s orchestrating vector databases, tuning inference latency, or designing interaction models, I’m driven by outcomes that compound value for teams and users alike.
