I used to build virtual worlds.
Now I build data pipelines.
The obsession with clean systems never changed.

About Me

Data Engineering & Systems

I'm a passionate developer with expertise spanning Virtual Reality, Artificial Intelligence, Database systems, and Digital Design. I thrive at the intersection of technology and creativity — building immersive experiences that solve real-world problems.

Currently pursuing an Engineering Degree in Information Technologies, I've led projects that reduced operational costs, built data-driven models, and created engaging 3D environments. I collaborate effectively in cross-functional teams and bring a detail-oriented approach to every project.

My multi-domain background means I can bridge the gap between design, engineering, and business — a rare advantage I bring to every team I join.

Biological Cells Animation

A photorealistic 3D animation of biological cells rendered in Blender Cycles. The project simulates cellular behavior — division, movement, and interaction — with hyper-detailed materials that replicate real electron microscopy imagery. A second EEVEE version presents five cell types simultaneously through a scientific microscope display panel.

ZGen — Freasky Original Character Design

An original IP — Freasky is the mascot and main character of ZGen, a personal game project. The design blends a whimsical, slightly spooky aesthetic with voxel art and low-poly 3D. The character lives in dark atmospheric forest environments, combining cartoon personality with a darker, moodier visual language.

Clubit — VR Polyrhythm Game

A standalone VR rhythm game for Meta Quest 3S built in Unity 6 with URP. Features a unique polyrhythm engine that simultaneously renders 4 geometric rhythm patterns (triangles/3, squares/4, pentagons/5, hexagons/6) drawn pixel-by-pixel on Texture2D — inspired by the musical concept of polyrhythms. Includes a fully interactive 88-key 3D piano (custom Blender model with individually named keys), FreePlay and SongPlay modes, JSON-choreographed songs, real-time session recording, and n8n webhook integration for data collection.
