Gustavo Vazquez · Founder & Developer

I build thoughtful software— for real problems.

I’m the developer behind Great-Visions, an independent software studio where I build original iOS products, web experiences, and selected commissioned client work.

Original Products

Great-Visions software developed from original ideas, practical problems, and continued technical learning.

Lead iOS project · In testing

LeasePace

A practical iOS app that helps drivers track lease mileage, understand their daily pace, and estimate potential overage costs before the end of a lease.

Project purpose
Help drivers understand their lease mileage pace early enough to avoid surprise overage fees.
My role
Independent iOS designer and developer, shaping the product, calculations, architecture, and SwiftUI experience.
Technology
Swift, SwiftUI, MVVM, SwiftData, Observation, and Xcode.
Key decisions
Keep persistence and app workflows separate from deterministic mileage analysis so projections stay testable and the interface stays focused.
The challenge
Turn dates, mileage allowances, odometer updates, and per-mile fees into guidance that remains accurate and easy to understand.
What I learned
How clear MVVM boundaries, input validation, calendar-day logic, safe previews, and focused tests make a practical app easier to evolve.
Current status

In testing. LeasePace is being refined and prepared for its first public release. Final screenshots and release details will be added as testing progresses.

Side project · HealthKit + storytelling

Step By Step

A fitness-powered text RPG that turns real-world steps into energy for branching stories. It combines daily activity, achievements, persistent stats, and narrative gameplay in one SwiftUI experience.

Project lineage

Survive became the flagship story.

The original standalone SwiftUI story taught me navigation and state management. Step By Step expands that foundation with HealthKit-powered energy, checkpoints, achievements, and replayable story paths.

Technical Contributions

Clear, practical documentation contributed to broader developer learning resources.

Currently building and learning

Inside the current build.

LeasePace is where product thinking, interface design, app architecture, and testing are coming together in one practical project.

Current phase
LeasePace Testing the experience and preparing the app for a first full launch.
Current technical topic
MVVM boundaries for presentation state, SwiftData persistence, and deterministic lease analysis using calendar-day calculations.
Most recent milestone
Refactored features into focused view models, added safe in-memory previews across key states, and verified Debug and Release builds with 10 focused unit tests.

About Gustavo

Building useful things. Sharing the journey.

Great-Visions is my independent software studio and the home for the software and digital experiences I design and build. I run it as a solo developer, creating original products and accepting selected commissioned projects where the work is a good fit.

My software development work is shaped by marketing education and extensive customer-facing sales experience. I care about whether something works technically, but also whether it communicates clearly and solves a meaningful problem for the person using it.

I continue developing original Great-Visions products, including LeasePace, while growing through commissioned work and technical writing. I’m also open to the right iOS development opportunity where I can contribute to a product, learn from an experienced team, and keep strengthening my engineering skills.
