How I Work Today · Coca-Cola

AI-Driven Development (AIDD)

The practice I'm building into my current role — using LLM integration and AI agents to speed up architecture analysis, implementation, and review without lowering the bar on quality.

LLM Integration AI Agents TensorFlow Lite On-Device AI

How I Work Today

Spec-Driven Development (SDD)

Structured specs that align Product, Design, and Engineering before a line of code ships — the habit behind less rework and more predictable release timelines on recent projects.
