Software Engineer · C# / .NET
Fullstack engineer at Finsolutia in Lisbon. I work on core-banking platforms in C# / .NET: scalable APIs, fast data access, and code that holds up in production.
I build the services behind financial products. Most days that means ASP.NET Core Web APIs, data access tuned with Dapper and SQL Server, and enough Clean Architecture to keep a growing platform from turning into a knot.
At Finsolutia I work in the Core Banking domain, shipping backend and fullstack features used in live financial operations. I started as an intern and earned two promotions in under two years, mostly by paying attention to how these systems actually behave in production.
I care about the unglamorous parts: query plans, clear contracts, honest code reviews. Away from the keyboard you'll find me at the gym, boxing, out on the bike, gaming, or tinkering with my homelab.
Jan 2026 — present
I build ASP.NET Core Web APIs for internal and client-facing platform features, and design services around Clean Architecture and the Repository pattern. A good chunk of my time goes into Dynatrace traces, hunting slow queries. Several of those rewrites took endpoints from seconds down to milliseconds.
Jul — Dec 2025
Promoted from the internship. I developed backend API features for fintech applications, wrote performance-tuned Transact-SQL, and helped raise code quality with SonarQube, Snyk and regular reviews inside an Agile team.
Nov 2024 — Jun 2025 · part-time
My first role in fintech, taken on while finishing my degree. I supported C# backend services, wrote and optimised SQL queries, tested APIs and fixed bugs across platform modules built on ASP.NET MVC, Razor and Kendo UI.

Algorithms and data structures, distributed systems, functional programming, Java and C. I finished the degree while already working full-time in the industry.
My main ongoing project is a three-node homelab: a NAS called Prometheus and two micro servers. It runs 24/7 and it's where I practise the same habits I use in fintech, from observability to security. The newest addition is a workflow of custom AI tooling for my day job.
A NAS and two micro servers running 25+ Docker services under Portainer. Media, automation, personal finance tracking, plus a dedicated AI node for local models.
The complete Grafana LGTM stack (Loki, Mimir, Tempo) feeding a custom dashboard, because I don't trust a system I can't see.
Defence in depth for services exposed to the real internet: intrusion detection, zero-trust access, and automated updates that don't break things.
I use Claude daily and build custom skills for it: small, reusable playbooks that speed up delivery and shorten QA on my .NET work, without giving up review discipline.
Same instincts, different scale. The observability and security habits from this rack are the ones I bring to Core Banking.
Fintech backend engineering, banking systems, and data platforms where performance actually matters. If that's your world, I'd like to hear from you.
