Most of my work sits around event driven systems, high throughput data processing, and scalable platforms. I stay close to the code. I design the architecture, then help the team build it the right way. I lead small, focused teams and set clear engineering standards. My goal is simple. Reduce complexity, ship faster, and keep systems easy to reason about as they grow. I've delivered trading platforms, high volume APIs, and large modernisation programmes. Each one improved performance, developer speed, or both. If you need someone who can design the system, guide the team, and ship the work, I'm happy to help. menos -
