Why Chrome extension UI automation becomes whack-a-mole
Notes from building AI Studio Prompt Library: scoped MV3 messaging, layered DOM selectors, Angular form events, and user-controlled selector fallbacks.

I build practical AI tools,
local-first browser systems,
and repo-native developer workflows.

SYSTEM NOTE
Operational simplicity compounds.
SYSTEM NOTE
DOM behavior matters more than framework choice.
SYSTEM NOTE
Boring infrastructure beats clever infrastructure.
SYSTEM NOTE
Agent failures usually start with state drift.

Notes From Building
Deep dives, Architecture decisions, implementation tradeoffs, and the engineering reality behind the systems I build.
02
Why PromptReady needed an offline Markdown baseline first
How PromptReady moved past generic page cleanup by making local Markdown capture, source metadata, fallback selection, and AI cleanup boundaries explicit.
03
Why semantic code search is not enough for coding agents
Notes on building Satori around deterministic MCP workflows, exact reads, stale-index warnings, and bounded retrieval contracts.
/ Domains
What I Build
Systems I actively work on, grouped by problem area.
AI Coding Systems
Repo tooling, MCP workflows, semantic retrieval, context infrastructure for coding agents.
Browser Tools
Chrome extensions, page extraction systems, offline-first capture, and local Markdown pipelines.
Product Engineering
Frontend architecture, dashboard interfaces, state management, and automation systems.
Research Tooling
Crypto pair research CLIs, statistical validation workflows, and paper simulation tools.
/ Projects
Projects I Built
A few practical tools, experiments, and case studies from my recent work in retrieval, browser tooling, and quantitative validation.
Project 01
search ──➔ retrieve ──➔ readSatori
Agent-safe semantic code retrieval for MCP coding agents.
AI coding agents often edit from partial repo context. Satori helps them search semantically, inspect symbols, follow call paths, and verify fresher context before editing.

Project 02
html ────➔ markdownPromptReady
Offline-first Chrome extension for rendered-page capture into clean Markdown.
Captures useful page content from messy web pages and turns it into prompt-ready Markdown for notes, research, and AI workflows.
Chrome MV3Local-firstMarkdownWeb extraction
Project 03
discover ──➔ validate ──➔ vetoQAP Crypto CLI
A crypto pair-testing CLI that asks which signals deserve trust.
Compares spot pairs, checks whether the data and setup are reliable, uses advanced dependency modeling to test pair relationships, and exports paper-run decision reports before any external execution path.

Experience
A compact view of roles and product areas. Full details live on the resume page.
Independent Systems Architect — B2B Consulting & Systems R&D
Audited B2B client applications to resolve interface latency and process friction. Engineered Satori MCP retrieval engine and PromptReady browser extension.
// Lessons about browser automation and state recovery started here.
TeamWave — Project Lead Developer
Led React/Angular frontend architecture and WORKAI AI product delivery. Built custom Angular canvas e-signature canvas engines to bypass third-party library constraints.
// Solid frontend architecture is about state, not styles.
Unbanking DAO — DeFi Frontend Lead
Designed wallet-connected swap/liquidity interfaces. Built React state machines managing multi-provider transaction approvals and RPC recoveries.
// Simulation is cheaper than production mistakes.
ClearTax India — Frontend Developer
Developed high-density tax filing form validators. Built a Node.js Puppeteer scraping pipeline migrating 1,500+ rich-text articles in 1 month.
// Learned the value of clean, repeatable forms at scale.
Freelance — Frontend & UI Developer
Designed Figma wireframes and built responsive Angular client interfaces paired with custom automation scripts.
// Most project failures begin as scope failures.
