About Me
Hello, I am Nelson, a Tech Lead and Full Stack Developer specializing in transforming business ideas into real-world applications, with deep expertise in enterprise development and mobile solutions.
I thrive on turning concepts into products, working closely with stakeholders to understand business needs and deliver scalable, maintainable solutions. I have two kittens 🐱 and I love to stay on the cutting edge of technology.
My expertise spans Full Stack Development (C#, Node.js, React/Next.js), Mobile Apps, Platform Engineering, and DevOps.
Currently focused on enterprise solutions and mobile application development. I also dabble in blockchain consulting.
I'm a very pragmatic guy. I work with technologies that deliver results and solve real business problems:
The Journey
My mission is simple yet profound: transform business ideas into living, breathing digital products. I thrive in that magical space where a business concept meets technical execution and becomes reality.
From understanding business requirements to building robust solutions with C#/.NET, Node.js, React, and Next.js, I orchestrate the entire journey of making products production-readyand delivering real business value.
As a Tech Lead, I bridge the gap between business vision and technical implementation. Whether it's building beautiful UIs with React and Tailwind, scalable APIs, or mobile apps, I ensure products don't just work—they solve real problems.
My approach combines solid engineering practices with modern DevOps workflows—Docker, Kubernetes, GitHub Actions CI/CD, and infrastructure that scales. I also dabble in blockchain when opportunities arise.
And yes, I absolutely ❤️ AI agents like Claude Code and GitHub Copilot. They're not just tools—they're force multipliers that unlock our potential to do more, better, and in less time.
