Software Engineering

No noise, no trends, no rush.

About

LYVATH is the brand.

And I'm Ryan PINA-SILASSE, the software engineer behind it.

Specialized in React, Go and their ecosystems.

That expertise comes from one clear decision: depth over breadth.

No trend-chasing, no unnecessary complexity, just solutions built to last.

Work process

Listen to the real problem Learn the constraints Apply the right solution Measure the result Repeat

Personal record

  • > Cut API latency by 99% on a production system serving a 2M+ part catalog.
  • > Reduced JavaScript payload by 93%, rebuilding a legacy site from scratch.
  • > Migrated legacy platforms to modern stacks with zero downtime, every time.

🎯 My goal is simple:

Creating things and solving problems is what drives me.

I keep both as simple as they need to be, nothing more.

That's what I bring to every client: a solution that actually solves the problem.

Not another pitch deck, just results.
