Oscar García
Engineering Management and Software Architecture
Hi, I'm Oscar García — a Barcelona-based engineer and engineering leader. Twenty years in, I'm currently Tech Lead and Engineering Manager for the Finance Area at SeQura, where I split my time between technical work and leading two teams of engineers.
I care about clean system design, honest engineering culture, and building teams where people are proud of what they ship. Away from the keyboard, you'll find me cycling, reading, or deep in a manga series I should probably have finished months ago.
About Me
Barcelona is where I grew up, studied, and eventually started building software. I studied physics at the Universitat de Barcelona — which taught me to think carefully about problems before reaching for solutions — and that instinct has followed me through a twenty-year engineering career.
My work is a mix of technical depth and people leadership. Right now that means leading two teams at SeQura, staying close enough to the codebase to have real technical opinions, and trying to create conditions where engineers can do their best work without unnecessary friction.
Outside work: my wife, two kids, and a steady rotation of running and cycling. I read a lot — sci-fi, mostly — and I have a longer-than-I'd-like manga backlog. Ask me about One Piece, Naruto, or Rurouni Kenshin and I'll happily go on for longer than you bargained for.
Professional Journey
Twenty years in tech have taken me through most layers of the stack — testing, data engineering, backend development, and eventually engineering leadership. That breadth turned out to be genuinely useful: understanding what each role actually feels like changes how you lead.
Around eight years ago I moved into management. Since then I've spent most of my time coaching engineers, shaping delivery processes, and making architectural decisions that need to hold up over years, not just through the next sprint.
Today I'm Tech Lead and Engineering Manager for the Finance Area at SeQura. After years leading larger organisations, I deliberately stepped closer to the work: two teams, a Ruby on Rails codebase, and a FinTech domain complex enough to keep every day genuinely interesting. Opening pull requests and being close enough to spot problems before they become incidents — I don't take that for granted.
Consultancy Services
Alongside my day job, I take on a limited amount of consulting work. Here's where I can actually help.
Software Architecture
Reviewing or shaping system architectures — helping teams make decisions that hold up over time, not just through the current sprint.
Engineering Leadership
Support for engineering managers and tech leads working through team dynamics, hiring, or the transition from individual contributor to leader.
Technical Strategy
Helping engineering organisations align technical direction with business goals and build a realistic roadmap to get there.
Code Reviews & Audits
A focused look at your codebase — what's working, what's quietly accumulating risk, and where to focus attention next.
If any of this sounds relevant to what you're working on, let's talk.
