What I'm looking for

I'm looking for remote, hybrid, or relocation opportunities where I can build secure FinTech products, expand AI-augmented QA automation, and contribute across full-stack engineering, testing, security, and CI/CD.

At SabPaisa, I architected and co-developed an enterprise Payment Gateway from scratch, building payment initiation, transaction processing, settlement, and refund services with Java, Spring Boot, React, Kafka, Redis, and PostgreSQL.

I combine full-stack delivery with quality engineering, creating merchant checkout experiences, developer integration documentation, reusable Playwright components, API automation, and Android and iOS test suites.

My automation and CI/CD work reduced testing cycle time by 35% and improved release stability by 40%. I also delivered 200+ UI and API automated test cases, 150+ Python API tests, and performance testing for 10,000 concurrent users.

I strengthen payment security through BurpSuite and OWASP-based API testing, uncovering 25+ vulnerabilities. I also built an AI Testcase Generator using the OpenAI API and a Django-based Testcase Manager adopted by 15 QA engineers.
