AI Agents Rajath Kumar · Jun 27, 2026
AI agents aren't just prompt chains. LangGraph brings state machines, conditional routing, and human-in-the-loop to LLM workflows for production agents.
ML / DL Rajath Kumar · Jun 27, 2026
Full fine-tuning is expensive and wasteful when you only need domain adaptation. LoRA trains 1% of the parameters, quantizes to INT8, and runs on edge hardware.
MLOps / LLMOps Rajath Kumar · Jun 27, 2026
Serving LLMs in production isn't just loading a model in Flask. Learn vLLM for high-throughput inference, Docker for reproducible deploys, and the ops layer.
OpenCV & Vision Rajath Kumar · Jun 27, 2026
Stream video from an ESP32-CAM, process frames with OpenCV on the edge, and run lightweight inference — all without a cloud dependency.

Basic RAG retrieves and generates. Production RAG uses hybrid search, cross-encoder reranking, and grounded citations. Here's how to build the latter.
ML / DL Rajath Kumar · Jun 27, 2026
Stop copy-pasting PyTorch boilerplate. Understand tensors, autograd, datasets, and training loops from the ground up — the way an engineer should.
Embedded Systems Rajath Kumar · Jun 26, 2026
Most ESP32 tutorials ignore dual-core pinning entirely. Here's how production firmware uses both cores — with real task allocation patterns from the field.
Embedded Systems Rajath Kumar · Jun 25, 2026
Most IoT tutorials default to HTTP without explaining why. Here's a head-to-head comparison of MQTT and HTTP from a firmware engineer who deployed both.
Embedded Systems Rajath Kumar · Jun 23, 2026
Stack overflows are the #1 silent killer of ESP32 production firmware. Understanding IRAM, DRAM, stack and heap allocation is the foundation of stable firmware.
Edge AI Rajath Kumar · Jun 22, 2026
Running a trained anomaly detection model on an ESP32 with no cloud. Here's the full pipeline — data collection, training, quantization, and inference.
IoT Architecture Rajath Kumar · Jun 21, 2026
Most AWS IoT tutorials skip the hard parts — certificates, device shadows, reconnect logic. Here's the production setup that survives in the field.
Embedded Systems Rajath Kumar · Jun 20, 2026
The Arduino loop() runs one thing at a time. FreeRTOS runs many — simultaneously, reliably, with priorities. Here's why every serious ESP32 project needs it.

No API keys, no cloud costs, no data leaving your machine. Ollama makes running LLMs locally practical for engineers who want real AI integration.
Engineering Career Rajath Kumar · Jun 18, 2026
The Indian embedded systems job market is growing fast — driven by EV, defence, IoT, and Edge AI. Here's the skills roadmap, salaries, and companies hiring.

RAG sounds complicated. It's not. Here's how to build a working pipeline that answers questions from your own documents in under 50 lines of Python.
Build Log Rajath Kumar · Jun 15, 2026
Six months in, one cohort complete. Here's what I got wrong, what I almost quit over, and what the data showed about embedded systems education in India.
