Prithvi — a fast, in-memory key-value database 🔥 built from scratch in Java. Designed for speed, simplicity, and control, Prithvi is engineered with: TTL & LRU Cache – Automatic expiry + memory-efficient key eviction Multi-threaded Architecture – Handles concurrent clients with zero lockups Disk Persistence + WAL – Crash-safe with write-ahead logs and JSON dump JWT-style Auth – Custom-built authentication layer from scratch Rich Data Types – Strings, Lists, Sets — with native commands Prometheus Metrics – Real-time internal observability Custom TCP Protocol – Raw, low-latency control over operations Official SDKs – Plug and play access for NodeJS and Python apps Open-source, transparent, and intentionally minimal — Prithvi is a developer’s DB, built to be hacked, extended, or embedded. Inspired by Redis, but purpose-built as a prototype that you can understand end-to-end.
Built it out of curiosity.

Thumb POV
I built ThumbPOV because I was tired of seeing the same flat, generic thumbnails everywhere. I wanted something that looked cinematic — like the text was part of the scene, not just slapped on top. ThumbPOV lets you put text behind your subject in seconds, no Photoshop skills needed. It’s quick, fun, and honestly kind of addictive once you try it. Would love to hear your feedback, ideas, or even see what thumbnails you create! 🚀
