About Alex Su

Our Story

I started writing code in 2009, fresh out of school with big ideas and shaky fundamentals. Since then, I’ve built software for Fortune 500 companies, venture-backed startups, and everything in between. I moved to Miami in 2015 and started focusing exclusively on helping local businesses solve complex technical problems.

Over the past 15 years, I’ve shipped over 50 production applications, led teams of 5–12 developers, and helped companies scale from 1,000 to 1M+ users. I’ve also learned what doesn’t work—the false promises of “move fast and break things,” the technical debt that buries teams, the architecture decisions that cost millions to fix later.

Now I focus on helping Miami businesses avoid those traps and build software that actually works.

Why Choose Me

I listen first. Before writing a single line of code, I understand your business constraints, your team’s capabilities, and what success looks like. That shapes everything—tech choice, timeline, scope.

No unnecessary complexity. Startups hire me because I don’t over-engineer. Fortune 500 companies hire me because I don’t cut corners. I pick the right level of sophistication for your problem.

You understand what I built. Bad projects leave you dependent on the developer. I document code clearly, train your team, and hand off working systems you can maintain or pass to someone else.

Production reliability matters. I’ve debugged 3 AM page-outs. I’ve restored databases. I’ve worked backwards from lost revenue. That experience shapes how I think about deployments, monitoring, and disaster recovery.

You get realistic timelines and budgets. I don’t guess. I estimate conservatively based on scope. If something changes, you hear about it early—before it derails your launch.
