About this gig

Is your business running on messy spreadsheets? I'll turn your Excel or Google Sheets into a real web app, with login, a proper database and dashboards, so your team stops copying data by hand.


What you can get:

  • Forms to add and edit records, with validation
  • Tables with search, filters and sorting
  • Dashboards with charts and key numbers
  • User accounts with different permissions
  • PDF reports, and email or WhatsApp notifications


Real results:

At a solar energy financing company, I replaced their Excel process with a web platform. Credit simulations went from 40 minutes to 2 minutes, and their partner network grew 32%. I also built a full management platform for a political office, with 8 advanced data tables and dashboards, used by the team every day.


How it works:

  1. You share your spreadsheet and explain your process
  2. I propose the screens and build the app
  3. I deploy it online and hand everything over with a short guide


Built with React, Next.js, Node.js and PostgreSQL.

I help businesses stop wasting time on spreadsheets and manual work. I build custom web apps, dashboards and automations, and add AI where it actually saves time. Today I'm the tech lead at a technology company, responsible for its products from design to production. Real results: a credit simulation that took 40 minutes now takes 2, and an AI setup that cut the company's AI tool costs by 82%. I work with React, Next.js, Node.js, Python and PostgreSQL. Tell me what you need to solve, even if you can't explain it technically, and I'll turn it into a clear plan.
