Hello, I'm

Prithivirajasingh K

Hardware & Embedded Systems Engineer  ·  Homelab Builder

Engineering professional with 5+ years at HCL Technologies delivering mission-critical systems across aerospace, medical, and semiconductor domains — from ATE design for aircraft braking systems to FPGA-level board design for wafer fabrication. I bridge hardware depth with a strong software instinct, and I build things end-to-end.

About

Who I am

I'm an embedded systems and hardware engineer who is equally comfortable with an oscilloscope and a terminal. At HCL Technologies I built automated test equipment from proposal to delivery, led teams, worked across regulated industries, and consistently shipped in high-stakes environments.

In my personal time I run a self-hosted homelab — a full Docker stack on ARM single-board computers, including a WireGuard VPN server, reverse proxy, automated media pipeline, and Python-driven infrastructure bots. I approach personal infrastructure the same way I approach professional engineering: documented, version-controlled, and production-quality.

Where I've worked

HCL Technologies Ltd
Member Technical Staff
Aug 2014 – Feb 2020  ·  India

Full-time engineer across three engineering domains over 5.5 years, delivering hardware and software solutions for mission-critical systems. Recognised for technical breadth, teamwork, and consistent delivery on complex, high-stakes projects.

✈️ Aerospace

  • End-to-end ATE design for aircraft braking & fuel gauging systems
  • Board bring-up: component selection, layout verification & testing
  • LabVIEW automated testing — improved efficiency and reliability
  • I2C & CAN protocol integration for reliable inter-device communication
  • Cable harness design to stringent aerospace standards
  • PDR / CDR client presentations and Electrical Interface Documents
  • Root cause analysis and debugging of complex field issues

🏥 Medical Devices

  • Device Master Records (DMR) for regulatory compliance and product quality
  • Led team to optimise and streamline data processing workflows
  • VB macro automation for productivity improvements

🔬 Semiconductor

  • Board-level design, validation, and obsolescence management for wafer fabrication
  • Schematics in OrCAD; current limit circuit design
  • PSpice simulations and detailed layout reviews
  • FPGA / CPLD design and high-speed digital interface implementation
  • PCB layout oversight; vendor collaboration for schematic capture
  • Obsolescence management — identifying and qualifying replacement components

Personal Projects

What I build at home

🏠

Self-hosted Homelab

Full Docker-based infrastructure stack on ARM single-board computers (OrangePi). Reverse proxy, VPN, media server, Samba, and automation — all containerised, version-controlled with git-crypt encrypted secrets, and documented.

Docker Compose Linux OrangePi SWAG / Nginx
🔐

WireGuard VPN Server

Home WireGuard server with multi-peer configuration, giving remote devices full-tunnel access to the LAN. iptables NAT masquerade enables transparent routing into the home network from anywhere.

WireGuard iptables Docker Networking
🤖

Python Automation Suite

Collection of Docker-hosted Python services: Cloudflare DDNS updater, Telegram bot for remote torrent management across multiple servers, Flask API endpoints, and an intelligent pCloud sync monitor with stability detection before upload.

VPN-tunnelled Media Stack

qBittorrent running inside gluetun's VPN network namespace (kill-switch enabled), with automatic post-download processing scripts and cloud backup via rclone to pCloud — triggered only when files are stable.
