Experience and real projects
Each project has a dedicated case study covering both the business problem it solved and the engineering decisions behind it.
Retail · Auto PartsA multi-branch point-of-sale platform engineered as a SaaS product for retail businesses of any size.
Retail · E-commerceAn all-in-one commerce platform with shared business logic and a fully custom storefront per brand — plus an AI assistant.
TelecommunicationsA React Native app that turns on-site incident reporting into structured, photo-rich PDFs for a telecom support team.
Healthcare · Non-profitA pro-bono care-management system that moved a non-profit elderly home off spreadsheets — later re-engineered on a stronger stack.
Also on the workbench
Personal ProjectA personal project exploring real-time messaging and video calls with a clean, responsive UI.

Who Am I and What do I do?
I'm a Computer Engineering graduate who loves turning tangled, manual workflows into software people can trust.
Over 2+ years I've shipped scalable platforms and automation across retail, healthcare, and telecommunications, from a multi-branch point-of-sale SaaS to a hybrid e-commerce platform with a self-hosted AI assistant. I care deeply about modeling complex business domains and keeping code maintainable long after launch.
I also use AI assistants as a serious engineering tool — pressure-testing design decisions and hunting for weak points, while always staying the one making the call.
How I build
Clean Architecture
Business rules isolated from UI and data.
SOLID Principles
Maintainable, well-structured code by design.
Automated Testing
Vitest, Jest & Playwright across the stack.
Industries served
Retail
POS & e-commerce platforms
Healthcare
Care-management systems
Telecom
Field reporting apps
