About Me

Hello, I'm Vivens

I'm a Software Engineer and systems builder with 8+ years of experience designing and developing scalable, high-performance applications across web and mobile platforms. I specialize in backend systems, real-time architectures, and developer tooling, while remaining highly effective across the full stack.

My work focuses on building reliable, data-driven systems - from API design and distributed services to user-facing interfaces and deployment pipelines. I have hands-on experience developing microservices, event-driven systems, and real-time applications using technologies such as Fastify, Redis, WebSockets, and PostgreSQL.

I'm particularly interested in building tools and platforms that improve workflows, automate processes, and ensure high data quality across systems. My approach emphasizes clean architecture, performance, and maintainability, with a strong focus on solving real-world problems through well-structured engineering.

I enjoy designing systems that power real-world operations — especially internal tools, automation platforms, and data-driven applications that enhance efficiency and reliability.
