QA Engineer · AI-powered test infrastructure

Based in India. I build automated test infrastructure for Web3 and SaaS products, and design AI-powered QA agents that use LLM tool-use to generate, execute, and self-heal end-to-end tests.

Record a user flow once and keep a Playwright spec that heals. Fingerprints instead of brittle CSS selectors, with a RED gate so the spec has to prove it would have caught the bug.

03 / EXPERIENCE

Where I've built QA systems

From Cypress suites to Claude tool-use agents that generate, execute, and self-heal tests.

Upcover

Current

QA Engineer

March 2026 — Present

Remote

  • Built the Dorian QA Agent, a pipeline that converts Jam session recordings into structured, executable Playwright test intents using Claude and a semantic (testId/role/label) selector strategy.
  • Implemented a self-healing locator engine with confidence scoring and AI vision/DOM fallback, plus real-time SSE run streaming and observability.

Polymarket

QA Engineer (Contract)

May 2026 — July 2026

Remote

  • Built an AI-driven E2E QA platform for Polymarket's Web3 prediction-market app: a Claude tool-use agent (~20 tools) drives Chrome via accessibility-tree refs, makes explicit pass/fail assertions, and streams results to a live Next.js dashboard over SSE.
  • Built a fail-closed CLOB order-interception pipeline that verifies EIP-712 signed orders against UI-captured trade intent via cryptographic signature recovery, independent of LLM judgment.

Kinnect

QA Engineer (Contract)

January 2026 — August 2026

Remote

  • Built QA Autopilot, an intent-first QA automation platform (FastAPI, Playwright, Next.js) decoupling test intent from selector implementation, with a 3-tier self-healing locator engine (SQLite cache, smart cascade, Claude AI fallback) to cut flaky E2E failures.

Brahma.fi

QA Engineer

August 2024 — December 2025

Remote, India

  • Sole QA Engineer for Brahma.fi's DeFi product suite; built the Web3 automation suite from scratch using Synpress, reaching 90% automated coverage and cutting manual testing effort by 60%.
  • Automated E2E flows across Console.Brahma.fi, Swype.fun, and the Morpho AI Agent (200+ scripts); containerized suites with Docker/Kubernetes and wired them into CI/CD, tracked via Qase.io and Linear.

NEAR Protocol

QA Engineer (Contract)

January 2024 — April 2024

Remote

  • Manually tested the BOS and MDAO pages, resolving 100+ issues and cutting user-reported bugs from 50% to 5%.
  • Added Jest unit tests that fixed 40+ further issues.

Comviva

Engineer

January 2022 — July 2024

Bhubaneswar, India

  • Achieved 95% test coverage by developing 100+ Cypress UI automation scripts, and managed defect lifecycle through JIRA.
