Main projects

Products I've shipped

The four projects I'm proudest of, and what each one achieved.

01 · Fintech · Healthcare

Wiggle

Multi-tenant SaaS for veterinary groups: POS, treatment plans, invoicing, CRM and payments in one platform, delivered as a web app, a browser extension and online bill pay.

What I achieved

  • $2M+ processed every month across 15+ clinics and 5,000+ transactions.
  • Sole developer, working alongside the CTO, CEO and a QA, from the first commit.
  • A self-service portal reduced admin tickets, and AI-assisted plan ingestion sped up onboarding.

  • Prisma
  • PostgreSQL
  • AWS

02 · AI · SaaS

Phew.ai

AI content intelligence: personalized article feeds become ready-to-publish social posts in the brand's own voice.

What I achieved

  • 500+ articles an hour through the pipeline, with batching, retries and automatic fallback.
  • Led development and set the technical standards for a global team.
  • Mentored contributors while balancing performance, cost and maintainability.
  • Next.js

03 · Open source · Desktop

Bizzi DB

A private desktop workspace for PostgreSQL and MySQL: browse data, design schemas and run SQL, all on your machine.

What I achieved

  • Created and maintain it as open source (MIT) for macOS, Windows and Linux.
  • Local-only by design: no account, no cloud, passwords can live in the system keychain.
  • Change review, schema diagrams and a SQL editor with query plans in one workspace.
  • Tauri
  • Rust
  • React
  • PostgreSQL
  • MySQL

04 · Web · Mobile

SL Treinos

A coach dashboard and a student app on one backend, so trainers spend their time coaching instead of calculating.

What I achieved

  • About 70% less manual work for the consultancy.
  • Automatic volume calculation and load adjustment for every student.
  • Students log every set in the app, so coaches plan from real history.
  • Next.js
  • React Native
  • Fastify
  • Prisma
  • PostgreSQL

About

Built from scratch, run in production.

Senior full stack software engineer with 5+ years of experience building scalable products from scratch. I've led technical work in global teams, delivering critical platforms for healthcare, education, CRM, SaaS and e-commerce, and removing operational bottlenecks with high-performance solutions.

People I work with usually mention the same three things: clear communication when complexity is high, time management that protects delivery dates, and creative problem-solving when specs are fuzzy.
