I'm a full-stack engineer and the founder of Lealix IT Solutions. I build custom business web apps, B2B portals and multi-tenant SaaS, and I connect the tools a business runs on with API integrations and workflow automation. With experience as a tech lead, AWS Community Builder and educator, I bring engineering and delivery under one roof.

Selected work
Platforms I've designed and delivered, from the problem to the shipped result.
The new company website for Lealix IT Solutions: one Next.js site that presents its five platforms, seven service lines, team and build process, with project proposals built in.
Affordable, S3-compatible object storage that Lealix IT Solutions built for Philippine builders, with prepaid peso pricing, developer SDKs and account security built in.
A Lealix IT Solutions product family for attendance, events and organizations. Its first product, Talinexo Attendance, turns everyday phones into encrypted, offline-ready QR scanners and is already in use at a partner college.
An automated backup and recovery platform for FiveM servers: a Go agent streams encrypted MySQL snapshots to offsite storage with no temporary files and no server lag, managed from a web dashboard.
A personal project: an interactive map where you can anonymously share the things you have been holding back, at the exact place where they happened. A safe, real-time space for our unsaid stories.
A capstone project I led: a certification hub, similar to Credly, where people keep and share their certificates and badges, and partner organizations issue verified certificates directly.
Kind words
From clients, teammates and partners I've worked with.
A knowledgeable and supportive friend and colleague who always perseveres through challenges and is willing to share his knowledge and teach others. He’s someone you can learn a lot from, and his patience and willingness to help make him a great person to work with.
Exceptional Collaborative Research & Prototyping"Collaborating on our research laboratory’s web platform was an absolute breeze. The focus on code quality, thorough documentation, and user-centered design turned our initial research concepts into a polished, working prototype. Highly professional, adaptable to strict academic requirements, and genuinely invested in the project's success.
For our major IT project, we needed a scalable mobile and web application. From system workflow mapping down to UI polish, every sprint was delivered on schedule. The clear communication and willingness to explain complex implementation details helped us understand our own system inside out. Couldn't have asked for a better technical partner!

The 'Bulong' project is amazing! I loved freely and anonymously sharing my thoughts on the global map and interacting with others. My favorite feature is 'Heart Mode' a pin-locked private space where I can express myself without anyone reading it. I can't wait to see what they do next!
