About

I’m a backend engineer with 6+ years of experience building scalable, reliable systems across payments, compliance, content safety, enterprise SaaS, and consumer technology at PayPal, Vymo, and Traveloka. At PayPal, I work on content-moderation and compliance platforms supporting multiple payment products. I have led the design and delivery of real-time image-screening workflows handling 200 peak requests per second with 3–5 second end-to-end latency. I also drove a cross-functional content-takedown program that reduced turnaround time from 7–10 days to within 24 hours. My work spans distributed system design, event-driven workflows, state machines, cloud and database migrations, API performance, production reliability, regulatory reporting, incident response, and cross-team technical leadership. I enjoy taking ambiguous problems from requirements and architecture through rollout, observability, and production ownership. Earlier at Traveloka, I improved API latency from 1.2 seconds to 60 milliseconds and increased throughput by 10x through Java concurrency, database-query optimization, and Redis caching. At Vymo, I built high-throughput, asynchronous backend workflows for enterprise insurance platforms. My primary technical strengths include Java, Spring Boot, Node.js, microservices, distributed systems, GCP, BigQuery, Cloud Spanner, Redis, Kafka, AWS SQS, Kubernetes, and production observability. I also work with backend AI integrations and content-safety pipelines, with hands-on experience in Retrieval-Augmented Generation (RAG), Model Context Protocol (MCP), LLM tool use, and agentic workflows. I’m particularly interested in senior backend, distributed systems, backend platform, and AI platform engineering opportunities where reliability, scale, and technical ownership matter.

Work experience

Software Engineer 2 at PayPal, Nov 2024 - Present · 1 yr 11 mos, Bengaluru, • Led the end-to-end design of real-time image moderation for the No-Code Payment Solution, sustaining 200 peak requests per second with 3–5 second end-to-end latency across CSAM and adult-content classifiers, human review, false-positive restoration, and a screening-platform migration. • Owned product requirements, technical design, cross-team alignment, and rollout for content takedown across moderation, policy, and media systems. Reduced turnaround time from 7–10 days to within 24 hours and enabled integrations with Invoicing and Venmo. • Designed a client-agnostic, event-driven moderation state machine supporting soft deletion, restoration, re-deletion, and permanent deletion while preserving a complete audit trail across payment and fundraiser products. • Modernized content-moderation and tax services through a MySQL-to-Cloud Spanner migration, Harness CI/CD onboarding, and Java upgrades, improving deployment safety and remediating critical vulnerabilities. • Led an Edgecast-to-Cloudflare migration and implemented bulk and single-URL purging across Cloudflare and Fastly, validating sub-300 millisecond responses. Established monitoring standards and coached engineers on purge and error-handling patterns. • Designed partitioned BigQuery datasets for content-takedown analytics and regulatory reporting, reducing scanned data and controlling query costs while preserving auditability. • Diagnosed p95 latency above 20 seconds as an infinite reprocessing loop caused by a deadlock, coordinated remediation, and retired an unstable model responsible for recurring HTTP 500 errors. • Owned PagerDuty response for the moderation platform and built PhotoDNA mock APIs that isolated functional testing from vendor outages and cache inconsistencies. • Earned 22 PayPal Props recognitions, including VP-level appreciation, for technical leadership, end-to-end ownership, regulatory-launch support, platform modernization, and cross-team delivery.

Member of Technical Staff at Vymo, Jul 2023 - Sep 2024 · 1 yr 3 mos, Bengaluru, • Designed and scaled a high-throughput lead-management service using Node.js, MongoDB, and Redis, improving processing throughput through data-access and concurrency optimizations. • Built asynchronous distributed workflows with fault-tolerant retry queues, idempotent processing, and multi-tier caching for enterprise insurance customers. • Developed configuration-driven onboarding and notification workflows, allowing customer-specific behavior to be introduced without service-level code changes. • Received Excellence Awards for engineering contributions to high-throughput enterprise platform delivery.

Software Engineer at Traveloka, Feb 2021 - May 2023 · 2 yrs 4 mos, Bengaluru, • Owned backend microservices for internal merchandising systems supporting a consumer platform with more than 20 million monthly active users across Southeast Asia. • Reduced API latency from 1.2 seconds to 60 milliseconds and increased throughput by 10x using Java concurrency, database-query optimization, and Redis caching. • Built asynchronous event-processing workflows using AWS SQS and implemented Datadog telemetry for latency, failure-rate, and queue-health monitoring. • Used JMeter load testing to identify garbage-collection and thread-pool bottlenecks and validate system behavior under high concurrency. • Earned “Exceeded Expectations” ratings in two consecutive performance cycles.

Associate Software Engineer at Volga Infotech, Aug 2020 - Feb 2021 · 7 mos, Mumbai, Developed backend modules for a U.S. alumni platform using .NET Core and REST APIs. Improved complex relational-query performance by 65% through indexing and schema optimization.

Software Engineer Intern at Cyber Group Inc., Jan 2020 - Jul 2020 · 7 mos, Noida, Built an enterprise recruitment platform using the MEAN stack and contributed to the migration of selected services to .NET Core. Check out my work at https://www.github.com/senseihimanshu.
