I contributed to the development of a distributed enterprise platform built around microservices, APIs, authentication, and data-intensive backend services.
My role involved implementing and maintaining backend functionality, integrating services, designing API contracts, handling persistence, and supporting frontend applications consuming the platform.
A significant part of the work involved translating complex business requirements into maintainable software while ensuring that different components of the system could communicate reliably and securely.
Key areas of work included:
Spring Boot microservices
REST API design and implementation
Service-to-service integrations
Authentication and role-based authorization
Relational and NoSQL data persistence
Data mapping and transformation
Error handling and validation
Backend integration with Angular applications
Maintenance and evolution of existing services
Troubleshooting complex production issues
The project strengthened my experience in building maintainable backend systems, integrating distributed components, and working with large production applications where reliability, security, and data consistency are critical.

One site, two businesses 🏁
Kart Vlak sells off-road karts in Uruguay. They needed to sell directly to families and recruit distributors across the country, without running two websites.
So we designed and built one store in Next.js that does both:
→ Full-screen video hero with a high-energy look that matches the product
→ Product pages with spec bars and a 360° viewer to see the kart from every angle
→ Checkout with bank transfer or Mercado Pago
→ A step-by-step assembly video built into the site
→ A distributor section with its own meeting scheduler
Your website can be your store and your B2B sales channel at the same time.
Full case study on my profile.
Been freelancing on Contra and building a tool for freelancers at the same time lol.
It's called ProposalForge. You give it a client brief and your rate and it drafts the proposal, and I use it on my own drafts too.
It's live now and free to try (3 proposals, no card). The video shows a free checker I made along the way that marks the phrases that make a proposal sound like ChatGPT. No sign-in: proposalforge.site/check
I'm trying to see where people actually get stuck. What part of writing a proposal takes you the longest? The opening, scoping and pricing, or just getting started?
An automated n8n workflow that receives incoming leads via webhook, validates them, qualifies them with AI (Google Gemini), scores them, and syncs the result to Airtable without creating duplicates.
