About this gig

Struggling to keep up with manual processes, outdated systems, or ideas that never make it to production? I combine real software engineering with the power of AI to build solutions that actually work not just prototypes or no-code hacks.


What I deliver:

  • Custom software development tailored to your exact needs
  • AI-powered websites and web applications
  • Intelligent AI agents for support, sales, or internal workflows
  • Automations that eliminate repetitive manual work


Why work with me:

  • Real engineering background I don't just prompt AI, I architect and code robust, scalable solutions
  • Every project is custom-built for your business, never a copy-paste template
  • Clear communication throughout the process, with support after delivery
  • Whether you need a full application, a smart AI agent, or an automation that saves you hours every week, I bring together solid engineering fundamentals and cutting-edge AI to deliver results not just demos.

I am Lead Developer at nexgrow.dev, specialized in Next.js, Astro.js and Python. Design and develop web applications, high-performance sites and automated business systems. My differential: I integrate real AI into functional products — from intelligent automations to tools that transform how businesses operate. I don't just follow the trend, I bring it to production. If you're looking for a developer who understands both the code and the impact on your business, let's talk.
