Independent software developer
& technical consultant
I help businesses build, improve, and connect the technology they depend on.
02 / Selected work
Designed · Built · Migrated · Shipped
A selection of things I’ve designed, built, migrated, and shipped—from business websites and ecommerce stores to native iOS apps.
Web design & development
Professional presence
01 / Pérez Accounting
Designed and developed a professional website focused on communicating the firm’s services and making it easy for prospective clients to learn about the practice and get in touch.
Ecommerce
Stores people can run
02 / Azahar Online
Azahar Online needed to move away from a WooCommerce setup that had become cumbersome to manage.
Rebuilt the storefront on Shopify, migrated the store, and helped the client transition to the new platform.
A simpler ecommerce foundation the client could manage day to day without the overhead of the previous platform.
03 / Tartaruga Chic
Tartaruga Chic had outgrown its ecommerce setup. I migrated the store, reorganized inventory, and streamlined shipping so routine operations no longer require ongoing technical support.
04 / The Jewelry Therapy
Designed and launched a fine-jewelry storefront with more than 50 products and Shopify POS for pop-up events. The owner later closed the store; its final storefront is preserved in the Internet Archive.
Native iOS

05 / Intake: Daily Water Tracker
Intake makes staying on top of daily water intake effortless. Set a goal, log drinks with a tap, follow progress throughout the day, and use reminders to stay on target.
06 / Downpour: Rain & Sleep Sounds
Every raindrop is rendered live on the device and reacts to shifting wind, gusts, and rainfall intensity—a GPU-powered environment rather than a looping video.
03 / What I work on
Problem first · Technology second
Sometimes the right solution is a website. Sometimes it’s an integration, an internal tool, a mobile app, or custom software that doesn’t fit neatly into a category.
I work across the stack to figure out what needs to be built—and then make it happen.
Custom web applications built around the needs of the business, from customer-facing products to internal tools and workflows.

04 / About
Independent · Puerto Rico
Hi, I’m Antonio.
I’m an independent software developer and technical consultant based in Puerto Rico.
I’ve spent years building across web development, ecommerce, mobile applications, infrastructure, and emerging AI technologies. That breadth lets me approach projects from the problem first rather than starting with a predetermined platform.
Sometimes that means building from scratch. Other times it’s improving what exists, connecting two systems, automating a tedious process, migrating to a better platform, or figuring out why something isn’t working.
I work directly with businesses, consultants, designers, and agencies that need someone technical who can understand the problem and take ownership of the solution.
