About

Engineering with product judgment.

I care about understanding what needs to work for the business and building the system that makes it possible, with enough clarity for a team to maintain it.

Portrait of Héctor Acosta

I'm a Product Engineer and Software Engineering Lead. I build SaaS and fintech products end to end: understand the problem, design the system, ship increments, and own what happens after deployment.

I currently work on Samata Health and Bespire with Aptura Labs, continue collaborating with Fintelligentia, and build Atenhora, an applied-AI product in commercial validation.

My experience spans mental healthcare, B2B operations, payments, documents, real-time market data, and conversational automation. I'm comfortable working on new products and entering legacy systems that already have users and real consequences.

I care about the space between product and engineering: turning ambiguous business rules into clear flows, reducing technical risk, and leaving behind a system another team can operate.

Working principles

Context before code

Technical decisions start by understanding users, rules, and risks.

Verifiable delivery

I prefer increments that can be tested and operated over promises that are hard to measure.

Explicit complexity

I make the states, boundaries, and trade-offs that hide in systems visible.

Operating is building

A product does not end when it compiles: it must be observable, recoverable, and able to evolve.

Technical capabilities

Technology in service of the product.

I do not try to impress with a cloud of tools. These are the capabilities I use to make decisions, build systems, and own their operation.
