Welcome to my corner of the internet. This website is a personal blog which I use as a platform to document my learning journey and showcase it for the world to see.
The Hidden Cost of Microservices: Why Distributed Tracing Is Not Optional
Microservices architectures introduce latency and failure modes that traditional logging can’t capture. Distributed tracing provides end-to-end visibility, but implementing it correctly requires careful instrumentation.
Build a Blockwise INT4 Inference Engine: A Hands-On Portfolio Project
A hands-on build guide for a blockwise INT4 inference engine with packed-nibble weights, per-group scales/zero-points, and fused dequantizing GEMM — a portfolio project that demonstrates real systems and ML engineering depth.
Implementing Passkey Authentication with WebAuthn: Secure Session Rotation and Recovery
Learn how to implement passkey authentication with WebAuthn in production, covering secure session rotation, credential lifecycle management, and resilient account recovery patterns.
Build a Pure Python LLM Decoder from Scratch: Temperature, Top-k, and Top-p Sampling
A hands-on guide to implementing temperature, top-k, and top-p sampling in pure Python, with runnable code that showcases systems engineering skills.
Building a Speculative RAG Decoder with Retrieval-Token Speculation
This tutorial shows how to combine retrieval‑augmented generation with speculative decoding to cut latency while preserving factual grounding. You’ll build a runnable system that demonstrates real‑world performance gains.
