Builder
First

I approach every problem like a builder: understand the system, find what's broken, fix it properly. Whether it's architecting AI solutions or scaling teams, the methodology stays the same. Follow the flow until you find the problem.

How I Got Here

2017-2020Enterprise Foundation

Learning the Hard Way

Started in enterprise engineering where everything was legacy and nothing was documented. Best education ever.

  • Untangled monoliths that nobody wanted to touch
  • Built CI/CD that actually worked (deployment went from 4 hours to 15 minutes)
  • Learned that mentoring junior devs teaches you more than any course
  • Discovered that the best code is code that ships
2020-2023Leadership Evolution

Building Teams That Build

Moved into leadership but never stopped shipping code. Scaled teams while keeping velocity.

  • Grew engineering from 5 to 25 (without losing our minds)
  • Built platforms for 1M+ users (and dealt with every edge case)
  • Survived multiple funding rounds and technical due diligence
  • Learned that culture beats process every time
2023-NowAI Innovation

Marcelle Labs

Founded my own consultancy because I wanted to build without the bureaucracy. Now I help teams ship AI solutions that actually work in production.

  • Building AI systems that reduce manual work by 80%
  • Teaching teams to implement without the hype
  • Still coding every day (because how else would I know what works?)
  • Helping companies build engineering cultures that ship
Philosophy

How I Work

Every problem can be solved, every system can be understood. It's all just following the current until you find the issue.

Builder First

I don't just design systems—I build them. When I architect solutions, I'm thinking about the deployment because I'll be the one making sure it works.

Ship Over Perfect

Perfect code that never ships helps nobody. I believe in building, deploying, learning, and iterating. The best systems are built by teams that aren't afraid to deploy on Friday.

Vibe-Driven Development

After enough years, you develop instincts. The code feels wrong before you know why. The system has bad vibes before it breaks. I trust that feeling and teach teams to develop it.

The Real Stack

Yes, I know Kubernetes, microservices, and all the AI frameworks. But the real stack is simpler: Problems that need solving. Teams that want to build. Systems that need to work. Users who need value.

Beyond the Code

Same Builder Energy, Different Domain

When I'm not debugging production or architecting systems, I'm probably debugging something else—my home automation setup, an EV charger installation, or whatever project has caught my attention.

Home Automation

Building smart systems that actually make life easier, not more complicated.

EV Infrastructure

Installing and optimizing electric vehicle charging setups—same problem-solving, different voltage.

Hardware Projects

From Raspberry Pi clusters to custom PCBs—if it has electrons, I'm probably curious about it.

System Optimization

Whether it's code, circuits, or coffee machines—every system can be understood and improved.

Every system can be understood, every problem can be solved.

The mindset that builds production systems is the same one that figures out why the home automation is acting weird. It's all just following the flow until you find the problem.

Let's Build Something Real

I work with teams that need to ship, not discuss. If you're tired of consultants who haven't touched production code in years, let's talk. Whether you need AI implementation, technical leadership, or someone to help you scale without losing velocity, I bring the same energy: build first, optimize forever.
