Performance Reliability Engineer

2022 - Present

Remote

• Own the reliability, scalability and performance of ARIC (real-time fraud-prevention platform).
• Built an automation framework to eliminate repetitive deployment, scaling and RCA toil, cutting manual effort on production issues by ~20%.
• Implemented automated dashboard creation, monitoring and alerting, improving mean-time-to-detect and catching issues before they reach production.
• Contributed config-update deployments using Infrastructure as Code, with zero-downtime to the running system.
• Tuned the application end-to-end (JVM options, code review, database, profiling) for better throughput under production load.
• Analysed production behaviour via Kibana and Grafana dashboards to detect regressions early.
• Led incident response with multiple teams to resolve production issues and restore service.
• Ran load and stress testing (JMeter and others) as impact analysis before component and feature changes.
• Documented findings as blameless postmortems / runbooks after every engineering triage investigation.

NCR Corporations

CoE Performance Engineer

2018 - 2021

Edinburgh, Scotland, United Kingdom

• Led end-to-end performance and scalability for 12+ microservices powering one of the largest SaaS internet-banking platforms for US credit unions.
• Acted as primary point of contact for production issues — performing RCA and delivering actionable recommendations to improve reliability and throughput.
• Architected and maintained a global automation framework for performance testing, enabling scalable, repeatable execution.
• Defined and delivered accurate Workload Models (WLM) to drive load targets, test scenarios and KPI benchmarks.
• Monitored production using Dynatrace, Splunk and application metrics to validate performance and detect regressions.
• Led tuning across JVM configuration, code, database queries and profiling to enhance throughput and stability.
• Partnered with product teams to design test plans and build custom JMeter plugins/samplers aligned to production behaviour.
• Owned performance sign-off / production readiness for releases and verified post-deployment baselines to prevent degradation.

Envestnet Yodlee

Sr. Performance Engineer

2017 - 2018

Bangalore, Karnataka, India

• Owned the aggregation component layer (Yodlee Service Layer), ensuring performance and scalability met SLAs for response time, throughput and dynamic autoscaling.
• Responsible for capacity planning, JVM tuning, profiling and container sizing to support throughput efficiency in production.
• Led Java 11 migration, including PoC and transition from legacy CMS GC to G1GC, improving memory efficiency and reducing GC pause times.
• Tuned JVM performance via profiling and JVM-argument evaluation; conducted heap and thread-dump analysis to resolve latency, connection-pooling and shared-threadpool issues.
• Enhanced the CI/CD-integrated automation framework for performance testing (Apache JMeter), enabling cross-team pipeline adoption.
• Applied shift-left performance strategies, identifying bottlenecks and reporting issues early in the development lifecycle.
• Built and customised Grafana and New Relic dashboards, defining KPIs and visualising component-level metrics.
• Mentored junior engineers on framework usage, pipeline integration and performance best practices.

Wipro Technologies

Sr. Performance Engineer

2013 - 2017

Chennai, TN, India

• Consulted for high-profile Wipro clients including Lloyds Banking Group, Telkomsel, SBSA and Mastercard, driving performance initiatives across diverse banking and telecom stacks.
• Developed performance scripts using Web HTTP/HTML, SAP Web, RTE (SFTP), Ajax-TruClient, Java record-replay (Java RMI), Java Vuser and Web Services.
• Applied strong expertise in Apache JMeter, BlazeMeter, Octoperf and LoadRunner for test design, execution and analysis.
• Executed ATM/POS channel testing across the network, validating transaction flow and responsiveness.
• Conducted load, stress and endurance testing to assess performance under varying load.
• Monitored system-resource metrics and analysed logs to identify exceptions, errors and bottlenecks.
• Delivered detailed performance reports and contributed to the defect-tracking process, ensuring timely resolution.
