02 — Build log

Seven years. One before and after.

I learned the craft before AI. Then the ground moved.

Pre-AI

  1. MuleSoft · Salesforce

    Engineering intern

    Oct 2019

    Wrote the test strategy for Anypoint Platform components.

    The industry: React Hooks ship. Components go functional.

  2. MuleSoft · Salesforce

    Associate MTS

    Oct 2020

    React interfaces on top of Java and Scala services.

    The industry: Everyone goes remote. TypeScript becomes the default.

  3. MuleSoft · Salesforce

    Member of Technical Staff

    Aug 2021

    Full stack on Anypoint, with accessibility across my team's components.

    The industry: API-led connectivity and microservices everywhere.

Nov 30, 2022

ChatGPT ships

Before this line I learned to build. After it, I build with AI.

AI-native

  1. Clarifai

    Senior SWE · Frontend lead

    Feb 2023

    Led the team that made computer vision usable.

    The industry: GPT-4 lands. Every product wants an AI feature.

  2. Clarifai

    Senior SWE · Frontend lead

    2024

    Built the front-end frameworks the AI platform ran on.

    The industry: RAG, tool use and the first agents.

  3. Front

    Senior Software Engineer

    Dec 2025

    Shipped WhatsApp and Zoom Contact Center channels, with agents in my build and review loop.

    The industry: Agentic coding goes mainstream.

04 — Back end

Distributed, and ready to fail.

Services that talk over a bus, and transactions that undo themselves when a step breaks.

  1. The gateway is the only HTTP surface.
  2. Services talk over NATS, never directly.
  3. Reads are cache-aside: Redis first, then Postgres.

    05 — Agentic SDLC

    A software lifecycle, run by agents.

    Orchestra is a Claude Code plugin. Independent departments pass tickets to each other, from idea to release.

    1. 01The process lives in code, not prompts.
    2. 02Every transition is checked against evidence.
    3. 03Merges, releases and rollbacks are done by code, never by an agent.

    Let's build something that ships.

    I'm most useful where product, front end and back end meet.
