Ramkrishnan Thevar.
Hi, I'm rk — a technology enthusiast with over 13 years of experience building and supporting software in the fintech world. I enjoy solving problems, learning how things work, and exploring new technologies that make life a little simpler or more interesting. Whether it's software, automation, AI, or emerging tech trends, I'm always curious about what's next.
Outside of work, you'll usually find me tinkering with Raspberry Pi devices, running self-hosted services, experimenting with local AI models, or building something in my homelab just for the fun of it. I enjoy turning ideas into real projects, sharing what I learn, and embracing the endless cycle of curiosity, experimentation, and continuous learning.
A QR-based vehicle contact system that lets people reach a vehicle owner instantly by scanning a sticker, without exposing personal phone numbers.
An n8n-based AI agent chatbot running entirely on the homelab, with anti-hallucination prompting, date-anchored web search, and feedback handled via ntfy.
My personal self-hosted infrastructure: a live status dashboard, media stack, security tooling, and a growing set of services across multiple home servers.
A write-up on my self-hosting journey — from a single Raspberry Pi to a multi-machine setup running media automation, monitoring, and home automation tools.
