FernandoLeano

Co-founder & CEO of ZuraLog. Building fast systems and clean interfaces that ship.

Who am I?

I'm Fernando, a developer who likes building things people actually use. From polished front-ends to the products behind them, I care about the details most people scroll past.

Who
I am

A developer with a builder's itch. Happiest shipping real products, not just demos.

What
I build

Web apps end to end. Most recently ZuraLog, a product I design, build, and run myself.

How
I work

Small details, fast feedback, no bloat. If it doesn't feel right in motion, it isn't done.

  • Detail
  • Motion
  • Performance

Beyond
the code

There's a life outside the editor, and this space is reserved for it.

  • Music
  • Travel

How I Work.

Practice.

Free practice: prototypes, spikes, and throwaway branches. Cheap laps to learn the track before anything gets locked in.

Qualifying.

The setup gets locked: scope, stack, and architecture. One clean lap on paper so the race isn't improvised.

Race.

Heads-down build. Short stints at a steady pace, with pit stops for review and increments shipped lap after lap.

Podium.

Delivery and the debrief: a shipped product, measured results, and setup notes for the next race weekend.

Skills& Stack

Grouped, not a wall of logos: the tools I actually reach for, and where each one earns its seat.

Infrastructure & Tooling

Ship it and run it

Containerized deploys, orchestration, and cloud infrastructure with tight version-control habits.

  • AWS
  • GitHub

AI

Agents in production

Practical AI engineering: systems that retrieve, reason, and act inside real products.

  • Agentic systems
  • Retrieval pipelines
  • LLM integrations

Experience

Three capability lines, each backed by shipped work. Hover a card for the proof point.

Performance on autopilot

Built for speed

Every build is tuned like a race car: lean bundles, instant loads, no wasted weight. Speed is the baseline, not the stretch goal.

User experience first

Delight your users

Fast means nothing without feel. Every interaction gets tuned until it clicks, so people enjoy the drive as much as the destination.
