01 / MEET THE DEVELOPER

Gabriel Bassalo

Software Engineer · Backend .NET · consulting and projects · Salvador, BA

I started in 2015 supporting point-of-sale and ERP systems, then spent five years building software for city governments and municipal agencies. Working close to the people who use the software taught me to understand the problem before writing the solution.

Today I build .NET and C# microservices for the Brazilian Central Bank ecosystem at Celcoin, with messaging, serverless functions, CI/CD and observability. I apply DDD, SOLID and CQRS to keep systems secure, scalable and maintainable.

Besides my current job, I work with companies on consulting and projects: I help them move processes off paper, choose the right technology and launch digital products, from education platforms to local business websites. And I skate, which is why this portfolio is a skatepark.

In tech since: 2015
Current focus: Backend .NET
Live projects: 6

07 / CONSULTING

Technology that solves the right problem.

Digital transformation, products and integrations for companies and institutions

I help companies and institutions move past improvised digital setups: find the bottlenecks, decide what is worth automating and launch products people actually use. I work closely with you, in short deliveries, explaining every technical decision clearly.

What I can do

Digital transformation consulting
An assessment of current processes and systems, priorities for what to digitize first and an evolution plan with clear costs and timelines.
Web and mobile products
From prototype to launch: websites, platforms and apps with an admin panel, hosting and domain set up.
Back end, APIs and integrations
.NET APIs, system integrations, messaging and architecture for teams that need to scale safely.

How I work

Assessment1–2 weeks
Conversations with the people who use and decide, a map of processes and systems, and the points that cost the most time or money.
Deliverable: Assessment report
Plan1 week
Priorities, technology choices, cost estimate and a phased timeline that fits the budget.
Deliverable: Roadmap with timelines and costs
Deliveryin 2-week cycles
Building in short cycles, with something working to test at the end of each one and adjustments based on real use.
Deliverable: Product in production
Follow-upongoing
Monitoring, fixes, documentation and knowledge transfer so the team can carry on independently.
Deliverable: Documentation and support
