Building intelligent and autonomous systems across production AI, AI-driven full-stack applications, and robotics — LangChain, RAG, Next.js, ROS 2, SLAM, and Jetson edge AI.
|I'm Karthikeya Kollu, AI Engineer at TAP Innovations — a US HR tech company where I ship production LangChain and RAG pipelines and AI-driven full-stack applications across Paycom, Paycor, and QuickBooks. 2.5+ years remote, leading AI feature delivery end to end.
I also design full-stack autonomous systems on custom hardware — ROS 2 Jazzy with SLAM and Nav2 on Raspberry Pi 5, Jetson-optimized perception with TensorRT, and a Pixhawk + MAVROS drone. ECE background gives me firmware-level depth across embedded protocols and sensor interfacing.

Real-time object detection on Jetson Orin Nano Super. YOLOv8 optimized via ONNX export and TensorRT INT8 quantization, published as ROS 2 topics for downstream perception.
450 mm quadcopter built from frame up. Pixhawk + PX4 autopilot, BN-880 GPS, bridged to ROS 2 via MAVROS for programmable autonomous missions.
Shipping LangChain + RAG pipelines that automate HR tech across Paycom, Paycor, and QuickBooks. Insurance plan and work order data processing at scale. (Proprietary — details on request.)
Key milestones in my professional growth
End-to-end robotics stacks on custom hardware: ROS 2 Jazzy + SLAM + Nav2 mobile robot, Jetson Orin TensorRT vision pipeline, and a Pixhawk + MAVROS autonomous drone. Builds documented at karthnode.com.
Leading AI integrations and intelligent workflow development. Building AI-driven features using LangChain, implementing RAG systems, and architecting scalable automation solutions for HR tech.
Built scalable Python scripts for HR system automations. Developed integrations for Paycom, Paycor, and QuickBooks. Handled data processing for insurance plans and work orders. Progressed to leading small teams.
