Hi, I'm 0x1da49 — A Developer & Solopreneur. Currently into Building products.
I build useful software, digital products, and online resources. My work spans utilities, automation scripts, developer tools, data-driven sites, and independent projects focused on solving real problems — often with simplicity and ownership in mind.
Little Shops
Small digital experiments. A few products, a few experiments, and a lot of trying to see what feels useful enough to sell.
Online Dollar Store - I wanted to see how far a $1 digital store could go.
Render Assets - A small shop for ready-to-use 3D assets.
DataBookShop - I got tired of manual research, so I built data books that are easier to browse and actually use.
Stuff I Made Free
Things I built and decided to leave open for everyone. No paywall, no gatekeeping—just useful stuff I wanted to share.
GPUIKit - I kept making visual assets, so I put 50,000+ of them in one place. For $0.
designmd.lol - A little library of DESIGN.md instructions for coding agents.
Free Tools
Useful browser-based tools and utilities.
Pixelation Studio - Monochrome & geometric pixel art generator with high-resolution export
Dither Studio - Image dithering & error diffusion engine with 17+ algorithms
Gradient Mapping Studio - GPU-accelerated 2D spatial mesh & color ramp shader editor
Pricing Calculator - Creator platform & payment gateway fee comparison engine
