AboutEngineer turned product manager

Product, with
engineering muscle memory.

I'm a Product Manager. I came up through engineering — a BE-MBA in Computer Engineering, a year of full-stack freelance work in college, a stack of personal projects in C, Flutter, and Python — and that background still shapes how I read a PR, scope a spec, or decide whether a prototype is worth building before the doc is written.

I don't push code in my day job. I write specs, run discovery, partner with engineering, and design agentic workflows on top of the LLMs I trust. I prototype with Claude and Cursor when it's faster than describing, and I read the diffs my team ships.

Today that work happens at TestMU AI (formerly LambdaTest) — an AI developer-tools platform spanning AI test automation, visual regression, and cross-browser testing. I joined as Associate PM during the LambdaTest → TestMU AI repositioning and partner with peer PMs across the application layer.

Currently.

Day job

Associate PM at TestMU AI — working on the application layer of an AI developer-tools platform across AI test automation, visual regression, and cross-browser testing. A lot of time goes into agentic AI workflows for PRD authoring and backlog grooming.

Tinkering

Pathforge — a personal evenings-and-weekends prototype that explores what a single AI career-coaching surface could look like. Built mostly for myself.

Outside work

Running voidDopeArt — digital art, typography, and photography under one brand. Slow but steady.

Reading

Prompt evaluation literature, design-system migrations, and the collected writeups of every PM who has shipped agents in production.

01Of method

Read the diff before you sign the spec. The code already knows.

02Of leverage

Leverage is when the spec answers the next four questions before they are asked.

03Of taste

Specs should read like fiction: tight, inevitable, alive.
