Available for new opportunities
Hi, I'm Vivek Umrao.
"Most software engineers build on top of platforms. I build the platforms themselves." As a Principal Software Engineer and Systems Architect with 15+ years of experience, I specialize in JVM internals, enterprise scale, and device-level security.

Principal Software Engineer
Pegasystems
Mar 2025 — Present
Transitioned from Cognizant Contractor to Pega FTE via negotiated management release to drive platform architecture for AU / global time zone enterprise operations.
- Core JVM Runtime Architecture: Architected low-level Infinity Engine internals, including custom hierarchical class loaders, memory passivation algorithms, and lock-free concurrency, eliminating thread contention bottlenecks and sustaining 99.999% platform availability across global enterprise client deployments.
- Cold-Start Elimination & Priming: Pioneered pre-emptive class-load priming at container startup, eliminating JVM cold-start latency spikes and enabling auto-scaled Kubernetes pods to handle peak production traffic immediately, cutting scale-up latency by ~85%.
- 3x Throughput Distributed ID Generator: Architected a distributed, batch-based unique ID generation engine across multi-tenant nodes, decoupling database locks and dependency bottlenecks to achieve over 3x throughput gains under peak concurrent workloads with zero collision risk.
- Enterprise Data Privacy & PII Governance: Led engineering-wide PII data governance architecture (dynamic masking, cryptographic tokenization, access policy enforcement) across distributed engine logs and telemetry traces, ensuring zero sensitive data exposure and full enterprise compliance.
- Unified Hashing Modernization: Spearheaded the consolidation of fragmented legacy hashing algorithms into a centralized, extensible cryptographic library, reducing future upgrade overhead by ~40% across distributed microservices.
- High-Performance APIs & Connection Pooling: Engineered robust database connection pooling (HikariCP/custom adapters) and high-throughput RESTful integration APIs, hardening database resource recycling under high-concurrency failover conditions.
- Incident Command & 30% MTTR Reduction: Served as Tier-3 Incident Commander and RCA lead for high-severity customer escalations; led systemic architectural remediations that slashed mean time to resolution (MTTR) by 30% alongside 24/7 mission-critical on-call production governance.
- Engineering Multiplier & Quality Modernization: Chaired architectural reviews, authored technical RFCs, and modernized automated integration testing lifecycles with JUnit and Mockito, reducing regression cycles by 20% while mentoring senior engineers on JVM memory and concurrency patterns.
Lead Architect (Manager – Projects)
Cognizant
Sep 2021 — Mar 2025
Embedded full-time with Pegasystems as Principal Technical Lead & Contractor Architecture Governance.
- Technical Program Delivery & Architecture: Directed technical architecture and engineering delivery for core engine initiatives at Pegasystems, aligning cross-functional software development, QA, and platform reliability engineering squads across global delivery centers.
- Core Engine SLA & Passivation Governance: Owned architectural enhancements for low-level passivation strategies, thread-pool allocation, and database connectivity, ensuring strict performance benchmark compliance and SLA adherence across multi-tenant enterprise accounts.
- CI/CD & Deployment Acceleration: Architected end-to-end CI/CD release pipelines and automated regression test suites, cutting release cycle times by 35% and enforcing automated code quality gates across all contractor deliverables.
- Systemic Incident RCA & 25–30% MTTR Reduction: Led cross-functional incident triage and Root Cause Analysis (RCA) for critical enterprise production issues, engineering preventative runtime safeguards that reduced customer MTTR by 25–30%.
- Developer Toolchain Modernization: Drove enterprise-scale developer infrastructure modernizations, including Vagrant-to-WSL2 environment migrations and Bitbucket-to-GitHub transitions, standardizing developer workflows and slashing engineering onboarding time by 50%.
Staff Engineer (Systems & Mobile Security)
Samsung R&D
Jul 2011 — Sep 2021
Samsung Knox Platform & Enterprise Mobile Security R&D.
- Samsung Knox Security Architecture: Architected and scaled core platform security frameworks (Samsung Knox Guard and Knox Configure), deploying system-level Mobile Device Management (MDM) policy enforcement, hardware attestation, and biometric authentication across 100M+ global devices.
- Systems R&D & Patented Innovations: Led systems R&D, OS-level security hardening, and proof-of-concept initiatives, translating novel research into patented mobile security innovations and achieving feature parity across global flagship device lineups.
- Global Cross-Region Architectural Alignment: Served as principal technical liaison between South Korea R&D headquarters and international engineering teams, harmonizing technical specifications and strict performance benchmarks across 50+ global telecommunication carriers.
- Test Automation Harness Architecture: Built comprehensive multi-threaded test automation and integration testing frameworks (UI Automator, custom device harnesses), accelerating Agile delivery cycles by 40% and elevating release stability.
