Staff Software Engineer at Slack (2025-09 – 2026-04)

Led backend infrastructure initiatives for enterprise-scale platforms, collaborating across product managers, designer, data engineering, and platform teams to deliver critical business features and robust deployment pipelines.

• Directed the technical strategy and backend execution of robust A/A and A/B experimentation frameworks on Hacklang and Vitess, delivering engagement campaigns that directly increased Annual Contract Value (ACV) and Net New Annual Order Value (NNAOV).
• Hardened enterprise communication infrastructure by engineering an advanced client payload compression library and integrating AWS SES real-time virus scanning, securing dispatch pipelines and eliminating redundant HTTP invocations.
• Authored operational runbooks and technical specifications for outbox services, directly reducing on-call ramp time for new engineers.

Staff Engineer at Junglee Games (2024-01 – 2025-07)

Provided technical governance for high-throughput gaming infrastructure, partnering intimately with product, data engineering, and SRE teams to scale massive systems.

• Scaled distributed infrastructure to sustain 5M+ requests/minute with strict p99 under 250ms by engineering object pooling to eliminate GC stalls, layered caching, and migrating wire-format to Protobuf for a 50% serialization speedup.
• Architected a real-time feature engineering pipeline (Golang and Kafka) transforming raw B2B transaction streams into ML-ready features, powering downstream models that blocked malicious payloads and cut false positives by 50%.
• Established cross-domain data consistency by designing a universal Event ID and JSON contract adopted across multiple engineering domains, permanently resolving deduplication defects on a massive-scale platform.
• Designed a Dead Letter Queue subsystem with end-to-end distributed tracing, guaranteeing zero message loss under peak load and cutting RCA time from hours to minutes.
• Provided technical leadership to a distributed team of 18 senior engineers, driving code quality gates and the adoption of AI-assisted developer tooling.

Staff Software Engineer at R3 LLP (2023-01 – 2023-12)

Architected secure integration layers for sovereign digital currency platforms within a highly regulated, cross-functional financial environment.

• Architected the secure integration layer bridging central bank legacy APIs with a Corda DLT platform (Kotlin), enabling sovereign digital currency minting in a regulated production environment.
• Partnered with cross-functional banking, compliance, and platform teams to deliver minting, transfer, and settlement flows under strict regulatory SLAs.

Senior Software Engineer at Zeta.Tech (2021-11 – 2023-01)

Engineered and optimized enterprise messaging buses, IO application and observability stacks for high-volume, regulated traffic ecosystems.

• Re-architected the enterprise Kafka messaging bus (Atropos), eliminating stop-the-world connector stalls and tail-latency spikes, restoring broker efficiency for high-volume traffic.
• Extended the central observability stack (ELK, Prometheus, Grafana) with strict p90/p99 SLO telemetry and distributed tracing for automated anomaly detection.
• Built a secure file ingestion pipeline using AWS S3 pre-signed URLs with automated antivirus scanning, hardening data transport for the I/O service ecosystem.

Senior Software Engineer at JFrog (2021-01 – 2021-11)

Developed software composition analysis capabilities and robust internal tooling to accelerate integration testing and incident resolution.

• Extended JFrog Xray with source code scanning capability and a cron-driven vacuum management system to reclaim storage without user impact.
• Built a high-performance Golang service-mocking tool simulating platform APIs, decoupling downstream teams and accelerating integration test cycles.
• Designed observability pipelines and playbook-driven runbooks that cut platform MTTR by 50% during cluster incidents.

Senior Software Engineer at Zoop.one (2020-07 – 2020-11)

Built scalable backend services for identity verification and digital payment platforms.

• Built scalable microservices for a B2B KYC platform (Golang and Java) with OAuth 2.0 integration, securing authorization across tenant boundaries.
• Delivered digital wallet and payment integration with secure webhook-driven transaction state management.

Technical Lead at Cimpress India (2015-12 – 2020-07)

Served as a founding engineering leader, responsible for building print job services from the ground up while establishing core DevOps, QA, and deployment standards for the new organization.

• Drove a cloud-native re-platform to AWS ECS, Lambda, and Kubernetes, replacing legacy polling with event-driven broadcast, resulting in a 75% reduction in data propagation latency and 50% reduction in compute spend.
• Refactored core services around the pipeline design pattern in Golang, producing a memory-efficient, composable architecture that lifted team development velocity measurably.
• Authored foundational Golang modules and shared libraries adopted across multiple downstream services, accelerating new service bootstrap.
• Built CI/CD automation for containerized application delivery across heterogeneous compute environments.
• The foundational structure of the polling system underwent a significant re-architecture, transitioning it towards an event-driven architectural pattern.

Software Engineer at J.P. Morgan (Tavisca) (2014-02 – 2015-11)

Integrated complex, multi-supplier enterprise APIs for the travel sector.

• Integrated and validated five GDS RESTful APIs in C#, expanding multi-supplier inventory and unlocking new enterprise sales channels.
• Owned production support, deployment, and client training for integrated travel APIs.
