Cybersecurity Researcher

Necurity Solutions · Chennai, India

  • Designed and executed comprehensive security test plans for client web applications — OWASP Top 10, business-logic flaws, access-control weaknesses.
  • Performed API security testing with Postman — validating authentication flows, authorisation boundaries, input validation and error-response behaviour.
  • Designed phishing simulation campaigns as structured test scenarios — defining test conditions, measuring outcomes and reporting to stakeholders.

Web Security Analyst (Tier 2)

Sectigo · Remote · France

  • Investigated web security incidents with structured test methodology — reproducing, isolating and documenting root causes; validated remediations before sign-off.
  • Used SQL queries against production databases to validate incident scope, confirm data integrity and reproduce complex security scenarios.
  • Performed systematic regression validation of WAF rule changes with Postman — confirming threat blocking and no false positives.
  • Designed SMART signatures for automated security detection and documented each with test evidence and expected behaviour.

Feb 2024 – May 2024

QA Consultant

Capgemini · Nice, France

  • Led test strategy and planning for the Lufthansa LH airline IT project — defined test scope, coverage criteria and acceptance standards.
  • Wrote comprehensive test plans and strategy documents for new use cases; used Jenkins CI/CD pipeline to manage test execution.
  • Used SQL to validate data flows across carrier integration endpoints — confirming booking records, pricing data and availability responses.
  • Applied security-aware testing to authentication and access-control scenarios within carrier integration flows.

Jul 2022 – Dec 2023

QA Engineer

Onepilot · Paris, France

  • Sole QA engineer for a React-based production platform — independently owned quality including test planning, BDD/Gherkin acceptance criteria, manual execution, automation and release sign-off.
  • Built the Cypress automation suite from scratch — Page Object Model structure, critical user journeys, integrated into CI/CD with GitHub Actions and Jenkins.
  • Used Postman to test and validate all REST API endpoints — collections with environment variables, pre-request scripts and JavaScript assertions.
  • Used SQL and PostgreSQL to validate data integrity and verify access-control boundaries correctly isolated user data.
  • Introduced TestLodge for automated bug-reporting workflows, cutting defect tracking overhead and improving release readiness.

Oct 2021 – Apr 2022

QA Engineer

Stych · Paris, France

  • Managed full defect lifecycle using GitLab and Trello — triage, prioritisation, root-cause analysis and resolution tracking for a French fintech platform.
  • Used SQL to validate payment flow data, confirm transaction records and reproduce defects requiring specific database states.
  • Defined release-readiness standards and produced structured release metrics with risk identification and quality gates.

  • Built a linear automation suite for the web app using TestProject — first end-to-end automation in production, covering login and core workflows.
  • Used Jenkins CI/CD pipeline for automated test execution on each build — reviewing build reports and flagging failures for rapid resolution.

Sep 2017 – Jul 2019

Software QA Engineer

HCL Technologies · Chennai, India

  • Designed and executed manual and Selenium WebDriver-automated test cases across two enterprise product teams.
