Intro / Name

Franco Ferreira.

Product engineer — Buenos Aires

I don't just write code — I understand products end-to-end and build what creates business impact.

About / Bio

about

Judgment.

I build products from 0 to 1, turning ambiguous problems into production systems that customers actually use. I work across product, engineering, and operations — partnering with founders and users to understand workflows, identify the highest-leverage opportunities, and ship solutions that create measurable business impact.

My strength isn't coding — it's judgment. Understanding what to build, why it matters to the business, and how to get there pragmatically. Previously at HSBC, Aivo, and Ford Argentina, delivering systems used by large organizations across Latin America.

Work / Product

what I build

What I build.

Products that solve real business problems — not just features.

Company operations platform

Rely

Company operations made visible for non-US founders and internal teams.

Problem

LATAM founders struggle to form US companies — the process is opaque, manual, and scattered across providers.

Solution

Built a platform that makes company formation visible, stateful, and operable. Owned both product and engineering end-to-end.

Client work (sanitized)

Acelera

Turning vague AI expectations into tools teams actually use.

Problem

Clients had unclear processes and broad AI expectations. The hard part wasn't the model — it was understanding what actually needed building.

Solution

Translated messy operations into scoped tools — dashboards, automation, internal systems that teams could keep using.

Side / Projects

side projects

Side projects.

Built end-to-end — from idea to working product.

Embedded hardware

Lemon Box

Physical crypto dashboard — from concept to working device.

Problem

Needed a dedicated device for live market data — always on, no browser, no distractions, on a constrained microcontroller.

Solution

Built the full firmware: rendering, WiFi provisioning, touch gestures, audio alerts — a physical product surface for live data.

iGaming product

Timba

On-chain gaming platform — built from idea to MVP with the founder.

Problem

A founder had an idea for an iGaming platform but needed someone to build the entire product — games, wallets, top-up flows, and fair gameplay.

Solution

Owned everything end-to-end: smart contracts (coinflip, giveaways, snowball), Telegram bot with integrated wallets and tipping, oracle for provably fair gameplay, and landing page with game verifier.

Method / Approach

how I work

How I work.

I talk to users before writing code.

Most engineers build what's asked. I find out what's needed.

I ship the smallest thing that solves the problem.

Not the most features — the right one.

I own the outcome, not the ticket.

Code that doesn't create business impact is a hobby.
