Work History
Qa Lead Engineer
R Systems
12.2024 - Current
- Built Java Selenium WebDriver + RestAssured framework with Maven, TestNG, Page Object Model — +30% regression efficiency (CI runtime 100→70 min).
- Added API-driven RestAssured test suites, integrated via Retrofit-like clients and JSON Schema validation — -20% total execution (CI 50→40 min).
- Led team for API, web, and app integration testing; enforced CI/CD pipelines (Jenkins/GitHub Actions), code reviews, and branching strategy.
- Expanded end-to-end coverage for high-risk flows using data-driven and BDD (Cucumber) approaches — +25% coverage (40%→65% via traceability matrix).
- Implemented reusable Java Page Objects, Factory patterns, TestNG parallel suites, and RestAssured client wrappers — dev time -30% (5h→3.5h/test).
- Applied risk-based test prioritization, equivalence partitioning, and boundary value analysis — targeted coverage +20%; reduced escaped defects.
- Conducted RCA, added contract testing (Swagger) and automated assertions, implemented flaky-test mitigation and retry logic.
- Basic Python Robot Framework for desktop (AutoIt/Sikuli integration) — PoC: 15 tests, 80% pass rate.
- Familiarity with Playwright (TypeScript), async test runners, and cross-browser capabilities — PoC: 10 tests, 90% parity, +15% faster.
Senior Software Engineer

1 2020 - 11.2024
- Implemented Spring Boot microservices (RESTful APIs) with JWT auth, Swagger/OpenAPI docs, and scalable stateless architecture.
- Implemented comprehensive unit testing using JUnit5 and Mockito with strict TDD practices — achieved 95%+ unit test pass rate.
- Increased code coverage to 85%+ (JaCoCo) across services by writing targeted unit and integration tests; tracked coverage trends in CI.
- Integrated SonarQube into CI pipeline (Jenkins/GitHub Actions) for continuous code quality checks; remediated critical/blocker issues and reduced technical debt by 60%.
- Led MongoDB → ScyllaDB migration: designed data model changes, implemented bulk migration jobs, validated consistency, and optimized CQL queries — cut read latency by 50% at scale.
- Performed big-data relevancy testing for future flight schedules using Kafka + Zookeeper (coordination), Spark batch processing, and schema evolution testing — validated temporal accuracy and data completeness.
- Developed automated sanity and regression suites for Web and Mobile using Selenium/Appium integrated with TestNG and RestAssured — reduced manual regression effort by 70%.
- Implemented production monitoring: Grafana dashboards, Prometheus metrics, and alerting (threshold and anomaly-based); configured PagerDuty alerts and escalations for SLO adherence.
- Added payment domain testing: implemented end-to-end and contract tests for payment gateway integrations (PCI-DSS considerations), simulated payment flows, negative/fraud scenarios, chargeback handling, and reconciliations — achieved 99.9% transaction validation accuracy in PoC.
- Added flight domain testing: validated booking workflows, pricing/rule engines, inventory and PNR lifecycle testing, schedule change and disruption handling, fare construction, and ancillary services — ensured schedule consistency via Zookeeper-coordinated feeds and reduced itinerary mismatches by 45%.
- Implemented performance and security testing for payments and flight services: load tests (Gatling/JMeter), latency profiling, and vulnerability scans; enforced secure coding and data-protection practices across services.
Senior Quality Analyst

05.2017 - 01.2020
- Led migration of legacy POM Automation Framework to a Factory Model architecture (Java, Selenium WebDriver, TestNG, Maven) — improved maintainability and parallel execution, reducing flaky tests by 40% and execution time by 25%.
- Managed daily Production Checklist execution and monitoring (health checks, smoke tests, log inspections, config validation) to enforce release quality and SLA adherence.
- Owned and executed full regression suites for major releases (Web, API, Mobile); reduced release-cycle defects by 35% through automated regression gating.
- Built Appium mobile automation (Android/iOS) from scratch: device farms (ADB, XCUITest), capability management, and parallel execution on real devices and emulators — achieved 70% automation of core mobile flows.
- Implemented Selenium C# maintenance projects: refactored legacy tests, introduced Page Factory and dependency injection, and stabilized CI runs in Azure DevOps — reduced false-failures by 50%.
- Rebuilt automated test framework from scratch migrating Selenium suites to Java + RestAssured integration: standardized TestNG suites, RestAssured client wrappers, JSON schema validation, and centralized test data management — improved API test reliability by 30%.
- Designed and validated tests for scheduling services and backend jobs (Quartz, Spring Scheduler, cron-based workflows): end-to-end verification of job triggers, idempotency, retry logic, and failure recovery; detected and fixed timing-related race conditions.
- Added test automation for payment and flight scheduling services: contract tests (OpenAPI), integration tests, and end-to-end scenarios covering booking lifecycle, payment reconciliation, and scheduler-driven notifications.
Associate Quality Analyst

01.2015 - 05.2017
- Developed robust Selenium automation frameworks from scratch (Java Selenium WebDriver, TestNG, Maven, Page Object/Factory patterns) — increased automation coverage and reduced manual regression effort by 70%.
- Domain expertise in Insurance (P&C) : validated policy lifecycle, underwriting rules engine, rating/quoting algorithms, claims adjudication workflows, premium billing/reconciliation, and provider eligibility checks.
- Implemented preventive actions from process evaluations (root-cause analysis, checklists, automated health checks) — lowered quality lapses and repeat defects by 35%.
- Built and validated SSRS/SSAS reporting services: created automated tests for report accuracy, data integrity, and ETL validation.
- Led Oracle → MS SQL Server migration testing: schema mapping, data reconciliation, performance benchmarking, and cutover validation with 99.9% data fidelity.
