Ricardo De Guzman Jr.

Web Developer, DevOps, and Cloud Engineer

about

Full-stack developer, DevOps, and cloud engineer with 10+ years across game dev, web, and cloud infrastructure. I build applications end-to-end - not just the pages people click through, but the systems behind them: accounts and permissions, document uploads, reporting, and the cloud infrastructure that keeps it all running. Currently Head of Product at KargaX and Senior Full-Stack Developer at IFELSE - co-planning architecture with the CTO and supporting every dev there across client work including LG's OTA platform and battery energy storage system software. Previously CTO at Seaversity.

29 years old. Started on Unity3D games and AR/VR experiments before the web, back when <marquee> tags shipped without irony - still prefer things that are simple and work over things that are impressive and fragile.

In 2018, our team PCI Seaversity VR reached the Global Finalist round at NASA's Space Apps Challenge (Makati City / BGC), earning a Global Nominee spot in the Virtual Space Exploration category for Mars2Earth VR - I led the VR side. Covered on ABS-CBN's Bandila.

work

A selection, not the full picture - a lot of client work stays off here by NDA. Happy to walk through more in a call.

LG Energy Storage System (ESS) tooling

IFELSE / Full-stack + embedded

Updated and debugged Device Management Client and CLI tools for battery energy storage systems, across Windows-based (Gen 1/2) and Linux-based (Gen 3) generations. Also wrote a Rust compatibility shim replacing a Windows-only proprietary SDK dependency, so the client can be built natively for Linux.

IFELSE / Systems + Robotics

Middleware bridging a Manufacturing Execution System (Oracle), an autonomous robot fleet (Bear Robotics ACS), and PLC hardware - real-time order dispatch, hardware polling with retry/circuit-breaker logic, and a live operations dashboard. Ported from an original C# implementation to Go, then rewritten again in Rust for cross-platform deployment.

Terraform State Server

IFELSE / DevOps

Self-hosted remote state backend for Terraform, built from scratch rather than depending on a managed service - state locking and storage for infrastructure-as-code pipelines.

personal projects

Side projects built and maintained on my own time, outside client work.

AUM Attendance System
