## About

I am an SDET with over three years of experience\. I started my career in high\-stakes cybersecurity at HCL Technologies, and I am currently driving end\-to\-end test automation and application security testing for a FinTech wealth management platform at CacheTech Advisor Solutions\. At CacheTech, my main focus is building and scaling test automation from the ground up\. I built our Playwright and Pytest UI framework from zero automation, cutting manual release regression from 1 to 2 days down to under an hour across 70\+ critical user flows and 5 environments\. On the API side, I replaced an old, staging\-only JMeter setup with dynamic Postman and Newman collections that validate 400\+ REST APIs per environment with automatic AWS Cognito token refresh and Allure reporting\. I also serve as the Point of Contact for our Astra Security program, running weekly syncs with pentest and infrastructure teams, reporting security posture to the CTO, and performing hands\-on penetration retesting with Burp Suite against the OWASP API Top 10 to make sure resolved vulnerabilities stay closed\. My tech stack: \- Core Automation: Python, Playwright, Selenium WebDriver, Pytest, Page Object Model \(POM\), Allure \- API & Performance Testing: Postman, Newman, REST APIs, Locust \(Load & Rate Limiting\), JMeter \- Security Testing: Burp Suite \(Proxy, Repeater, Intruder\), OWASP API Top 10 \(BOLA/IDOR, RBAC, Privilege Escalation\), Astra Security \(DAST\), Python Security Scripting \- Infrastructure, Data & Ops: AWS \(Cognito\), Jenkins, Ansible, Git, PostgreSQL, MongoDB, Splunk, Tanium, Akamai Guardicore During my time at HCL Technologies, I grew automation coverage from roughly 10% to approximately 80% of critical functionalities across 10 mission\-critical cybersecurity applications for a tier\-1 investment bank by building out regression and smoke test scripts using Python, Selenium, and Pytest\. I also owned end\-to\-end release planning, handled multi\-layer production root cause analysis across network, OS, and database layers, and managed the full L2/L3 defect lifecycle in high\-availability environments\. I enjoy connecting with engineering teams that care about how software behaves under real\-world pressure\. What makes me different is that spending over three years embedded in mission\-critical banking and FinTech systems has taught me how software actually fails in production\. I do not just write tests\. I bring a production\-first mindset to my work, focusing on catching complex functional, performance, and security bugs before they ever reach the users\.

## Work experience

SDET at CacheTech Advisor Solutions, May 2026 \- Present · 7 mos, Logan, Utah, United States, At CacheTech Advisor Solutions, I lead end\-to\-end test automation, API validation, and application security testing for a FinTech wealth management platform serving financial advisors\. What I have built and delivered: • UI Automation from Scratch: Built a Playwright, Python, and Pytest framework \(POM\) from zero automation, cutting manual release regression from 1 to 2 days to under 60 minutes across 70\+ critical user flows and 5 environments \(25 to 35 minutes via parallel execution\)\. Used role\-based locators to keep scripts resilient against weekly data obfuscation and DB restores\. • API Test Scaling \(70\+ to 400\+ APIs\): Rebuilt an outdated, staging\-only JMeter setup into dynamic Postman and Newman collections with auto\-refreshing AWS Cognito auth, payload/schema validation, status code assertions, and Allure reporting across staging, test, demo, prod, and pentest\. • AppSec & Penetration Retesting: Drive the security program as Point of Contact with Astra Security, leading weekly triage syncs across pentest, scanning, and infra teams and reporting posture to the CTO\. I retest fixes using Burp Suite \(Proxy, Repeater, Intruder\) with authenticated JWT traffic, request replay, and payload fuzzing across the OWASP API Top 10 \(BOLA/IDOR, privilege escalation, RBAC, host header injection, HTTPS/HSTS, PII masking\), and automate security regression with Python and Newman\. • Performance & DB Validation: Scaled Locust load and rate\-limiting scripts to validate 20\.5 RPS stable performance, and verified data integrity in PostgreSQL \(DBeaver\) and MongoDB \(MongoDB Compass\)\. Key engineering highlight: Built a Python API health\-check scanner integrated with a GUI\-driven Ansible pipeline for deployment checks\. Teams select an environment and service via dropdowns with zero local setup; it authenticates via AWS Cognito, passes response data between dependent APIs, and outputs a consolidated pass/fail/error report\.

Software Engineer at HCLTech, Oct 2022 \- Nov 2025 · 3 yrs 2 mos, Madurai, Tamil Nadu, India, Worked as a Software Engineer and Subject Matter Expert \(SME\) across 10 mission\-critical Cybersecurity applications for a tier\-1 investment bank\. Key responsibilities and deliverables: • Test Automation & CI/CD: Developed and maintained Python, Selenium WebDriver, and Pytest automation scripts using the Page Object Model \(POM\) and data\-driven testing for daily smoke and release regression coverage, managing the codebase in Git and integrating test execution with Jenkins CI/CD pipelines\. • End\-to\-End Release Ownership: Owned release planning in collaboration with development teams for major and minor application and infrastructure upgrades \(Java, Tomcat\)\. Designed boundary and edge\-case test scenarios and facilitated UAT sign\-off with business owners, developers, and stakeholders to deliver defect\-free releases\. • Production Root Cause Analysis: Investigated and diagnosed complex production issues across network, OS, and database layers using Akamai Guardicore, Splunk, and Aegis\. Replicated issues in UAT, captured comprehensive logs and evidence, and collaborated with engineering teams to drive timely fixes\. • Defect Lifecycle & Deployment Certification: Managed the full lifecycle of production defects in Jira and ServiceNow from initial L2/L3 triage through verification and closure\. Executed post\-implementation sanity testing, automated regression, HTML test report analysis, and SQL data validation to certify production deployments\. • Proactive System Monitoring: Monitored server, database, and network health using Geneos, Grafana, and Tanium to identify performance bottlenecks and triage bugs before they impacted end users\.

Internship Trainee at HCLTech, Apr 2022 \- Oct 2022 · 6 mo, Madurai, Tamil Nadu, India, • Gained foundational proficiency in Core Java, Red Hat Linux, and SQL, developing a strong understanding of application architecture and operating environments\. • Supported software development lifecycle activities, contributing to initial system setup and basic testing protocols\.
