02loveslollipop - Just a ZeroTwo that really loves lollipop and a Computer and systems engineer & Data science engineer.
Introduction
Hi, I'm 02loveslollipop. I love technology, engineering, and building things in general. Even tough I'm a Computer and systems engineer & Data science engineer, I have a wide range of interests and like to explore different areas. This is a personal portfolio site where I share projects, writeups, and other content related to my interests and work.
Focus (Or lack thereof)
I love lot's of things as you will see in my projects and blog. I think the best way to understand the world is by building, but something shouldn't be built just for the sake of building. I like to build things that are interesting, that solve problems, or that are just fun to me. But also I don't like to be superficial in what I learn whatever the topic is, for me that's a way to show respect to that thing and to myself.

Bad Apple ESP32 Utilities
A clever suite of tools designed for retro-style ESP32 tech demos. Feed it a video and it slices the footage into frames, applies delta encoding and RLE compression, and outputs a bundled C array ready to be flashed directly onto an ESP32. While the original CodeMaker utilized a sequential Cython implementation, the Composite evolution features a modular, parallelized architecture running on Numba (CPU) and CuPy (CUDA GPU) resulting in exponentially faster encoding speeds, and adds native audio support.
- Modular architecture with CPU (Numba) and GPU (CuPy) acceleration
- Parallelized video encoding maintaining delta and RLE compression
- Included Composite ESP32 player with experimental audio

LoRa L298N Tank Controller
LoRa‑L298N‑TankController is a hobbyist IoT platform for remotely piloting a tank‑style rover via LoRa radios. ESP‑based controllers drive an L298N H‑bridge while encrypted commands and telemetry flow through Redis streams and a modular microservice backend hosted in Docker‑containers on AWS. It’s ideal for experimenting with low‑bandwidth long‑range control, real‑time media relay and distributed telemetry.
