About Santurce Software
An engineer's company.
A business-minded approach.
Santurce Software LLC is a Puerto Rico software consultancy and product company, founded by Jake Kalstad in 2021.
Building software since 2008.
Jake's career began in Oregon and continued through Idaho and New York City before bringing him to Canóvanas, Puerto Rico. His work spans enterprise steel fabrication software, marketplaces, advertising technology, construction platforms, and laboratory operations.
At AdQuire, he progressed from software engineer to VP of Engineering, leading a six-person team supporting systems handling millions of sessions each month. That work included modernizing a legacy platform into Go services, cloud operations, event processing, and reporting.
Today, Jake owns Santurce Software and personally designs, writes, deploys, and maintains FlaskTrack. His work combines hands-on Rust backend development, PostgreSQL data modeling, web interfaces, API and AI integration, and Linux infrastructure with product direction, architecture, infrastructure, and engineering leadership.
Leadership with implementation behind it.
Clients can engage Jake for software delivery, additional senior engineering capacity, or fractional technical leadership. The same person discusses the business problem, reviews the architecture, and works in the codebase.
Based in Puerto Rico.
We work with businesses in Puerto Rico and remotely with teams elsewhere. You work directly with the founder on priorities, technical decisions, and delivery.
