Product-minded senior software engineer

I turn product ideas and team workflows into useful software.

I work across interfaces, internal tools, automation, and AI-assisted processes, with attention to product feel, maintainable code, and everyday usability.

Selected work

Client systems across ecommerce, media, healthcare, hospitality, and monitoring-heavy internal tooling — plus GastosCasa, a product of my own that I design, build, and run.

Product engineeringOngoing

Building-wide PTAC control

A dashboard for operating the PTAC units across entire rental buildings. Operators trigger remote actions on a unit or a whole property, schedule device state changes ahead of time, pull usage reports, and manage account-level access to each building. Devices report over AWS IoT, so the interface has to stay honest about fleet state that arrives asynchronously.

ApplicationsRecent

Guided intake and follow-up

Multi-step applications that walk people through long forms, capture structured data, and hand it to the teams doing follow-up. Most of the work is state: partial progress, validation, and resuming days later without losing anything.

Web platformsRecent

Storefronts and content platforms

Public ecommerce and editorial platforms where the render path is the product — fast pages, CMS-driven content, and analytics clean enough for merchandising and marketing teams to act on.

Personal productOngoing

GastosCasa

A shared budget manager for households where several family members track expenses together. Everyone can log spending, review clear charts, organize recurring bills, and keep the monthly budget in order from the web or mobile. It also supports credit-card installments, multiple currencies, and inflation tracking.

Vivaire

A guided breathing app for web and mobile. People can build custom routines, follow timed sessions with audio and haptic cues, schedule reminders, review streaks and progress, sync their activity, and share sessions by link.

Experience

A career building web products end to end: system architecture, product delivery, performance, observability, and shipping across the stack.

About

I like software that gets out of the way.

I work across product, architecture, and implementation details, with a bias toward tools that are clear, fast, and easy to maintain. I have been building software since 2011: designing systems, writing backend services, building interfaces, and owning delivery, monitoring, and hiring.

My current approach is AI-assisted by default: I use modern development tools to shorten feedback loops, refine processes, and move from idea to working software as quickly as possible.
