Hello, I'm Edgar Pérez
Frontend Design Engineer
Your team feels stuck. Features drag, releases break things, and nobody can explain why. I find the structural problems and organize the way forward.
The Problem
Frontend complexity doesn't announce itself. It piles up quietly until shipping anything feels like a fight.
Features take longer than they should
Change one thing, five other places break. What should be a half-day task turns into a multi-day ordeal, and nobody can explain why.
New engineers take months to contribute
Knowledge lives in people's heads. Conventions are undocumented. Onboarding is ad-hoc.
Design and engineering are misaligned
No shared language, no design system governance, constant rework and miscommunication.
Performance degrades with every release
The app gets heavier with every deploy. Pages that loaded in 2 seconds now take 5. Your users noticed before your team did.
Most teams try to fix this by pushing harder or adding new policies without adding structure. That's aspirin. The real fix is structural, and that's what I do.
Who I Am
I started in Venezuela, led teams across startups and agencies, and shipped products used by thousands. A client once called me "the organizer." There's more if you're curious.

Four ways to work together, depending on where your team is right now.
High-End Frontend Consulting
I look at how your frontend is actually built, find the stuff that is slowing your team down, and give you a plan to fix it.
Custom Web Development
I build sites that work well and are easy for your team to keep running. WordPress, WooCommerce, stuff like that.
Long-Term Frontend Advisory
You get ongoing access to someone who thinks about frontend architecture for a living, without hiring full-time.
Who This Is For
Good fit
- + Founders who feel their team is stuck but can't pinpoint why
- + CTOs who know the codebase needs structure before it can scale
- + Engineering managers watching complexity pile up with every sprint
- + Companies hitting a breaking point where the current approach stopped working
Not the right fit
- - Teams looking for another developer to write code faster
- - Projects that need tutorial-level guidance
- - Organizations not willing to change how the team works
- - Early-stage startups still figuring out product-market fit
