About
Building reliability into AI systems.
I'm a Senior SDET with 6.6+ years of experience in distributed systems, API engineering, and backend validation for enterprise-scale applications. I'm currently at Iris Software Pvt. Ltd., working on behalf of National Australia Bank (NAB).
Over the past year I've been going deep into AI engineering: designing and integrating custom MCP-compatible tooling, building LLM-powered workflows, and shipping production AI projects independently.
My QA background gives me something most AI engineers don't naturally have: a systematic instinct for evaluation, edge cases, and failure modes. When I look at an LLM-powered system, I think about where it breaks, how to measure it, and how to make it reliable.

Iris Software Pvt. Ltd.
Gurugram, India
Client: National Australia Bank (NAB)
Senior SDET
- —Designed and integrated custom MCP-compatible tooling enabling LLM agents to perform multi-step workflows — API execution, database state verification, test case generation from technical documents, and artifact extraction — within an enterprise banking engineering environment.
- —Used agentic AI for root cause analysis — navigating complex enterprise codebases to surface bug locations and error context for developers, accelerating defect resolution.
- —Generated test cases autonomously from technical specification documents using LLM-based workflows, reducing manual test design effort significantly.
- —Built and embedded AI-generated blackbox tests directly in the development repository, enabling shift-left quality detection at commit time.
- —Validated Airflow DAG pipelines — verified Parquet file ingestion, data transformation logic, and downstream output to Kafka topics and databases.
- —Built Avro-based contract-testing framework validating microservice integrations and backward compatibility.
- —Automated Kafka schema and event verification, reducing integration failures across distributed services.
- —Delivered Java (Gradle) backend automation suites integrated into CI pipelines for early defect detection.
- —Implemented SQL-driven backend verification to reduce manual validation effort and improve data accuracy.
- —Optimized pipelines for faster, parallelized automation runs and steadier releases.
Orange Business Services

System Software Engineer
- —Led Pytest + Selenium automation for API, UI, and backend coverage, integrated with GitLab CI.
- —Owned microservice test strategy, coverage, quality metrics, and defect lifecycle.
- —Built REST API and backend validation suites using MongoDB, SQL, and JMeter for performance checks.
- —Partnered with DevOps to reduce flaky tests, scale pipelines, and stabilize CI/CD.
- —Created Python utilities for production data parsing and automated Excel reporting.
- —Mentored junior QA engineers and rolled out API testing best practices and sprint QA metrics.
- —Executed JMeter-based performance tests, identifying API bottlenecks, thread contention, and throughput issues.
- —Coordinated nightly validations, UAT cycles, and cross-team release testing with distributed teams.
Comviva Technologies (Tech Mahindra Subsidiary)
Gurugram, India
Automation Test Engineer
- —Automated 195+ Appium mobile test cases, reducing manual regression cycle time by more than 50%.
- —Built reusable Java + Appium modules for API/mobile automation.
- —Resolved 490+ defects via collaborative triage across multiple releases.
- —Performed Oracle SQL backend validations to ensure data integrity.
- —Managed regression, smoke, and integration suites for financial mobile apps.
- —Implemented custom scripts and utilities to accelerate test execution and environment readiness.
