About

I'm a software engineer and backend architect with 11+ years building complete products — from distributed systems that stay correct under load to the React interfaces people actually use. Most recently I was a Member of Technical Staff at PayPal, where I worked across several large-scale platforms. I designed core components of KAIROS, PayPal's communication decision platform — including a durable, leaderless distributed scheduler on Bigtable and Pulsar built to handle ~25–30M deferred intents a day with bursts of 2M due at a single instant. I also led the backend architecture for an in-house server-driven UI platform serving over 1 billion requests a day, and built web portals and tools around these systems end to end. The work I'm drawn to sits where correctness meets scale — distributed systems, schedulers, decisioning pipelines, high-throughput platforms, and the systems other systems depend on. I care about designing them well: atomic guarantees, idempotency, fault tolerance, clean failure recovery, observability, and architecture that holds up when traffic spikes. More recently, I've been working on AI and agentic engineering — building production workflows with Claude and Gemini, function calling, tool integration, MCP and RAG. At PayPal, I built a Communications API AI agent and MCP server that exposed platform capabilities for natural-language interactions and automated workflows. Because I've always owned features end to end, I'm also comfortable moving beyond the distributed core — designing APIs, building React applications, troubleshooting production systems, reviewing HLD/LLD, and working across teams to take systems from design to production. Before PayPal, I built platforms at Informatica and Envestnet Yodlee across security-flaw management, automated issue resolution, microservices and observability. Core: Java, Spring Boot, Distributed Systems, System Design, Microservices, Kafka, Pulsar, Bigtable, GCP, Kubernetes, AI Agents, MCP, RAG and React. I'm currently exploring Staff Software Engineer, Lead Engineer and Principal Engineer opportunities across backend, distributed systems, platform and AI/agentic engineering.

Member of Technical Staff at PayPal, Feb 2025 - Present · 1 yr 8 mos, Architecture and hands-on engineering across PayPal’s large-scale communication decisioning, distributed scheduling, Server-Driven UI and AI/agentic platforms. KAIROS — Communication Decision Platform Designed core components of a centralized decisioning platform that governs what every customer is communicated, when, and on which channel. Designed a distributed intent-management layer for ingesting and managing decision intents from producing systems. Architected a durable, leaderless distributed scheduler on Bigtable and Pulsar, engineered for tens of millions of deferred intents per day with large concurrent bursts — using atomic compare-and-set for single-fire dispatch and consumer-group hash-partitioning for coordination without a leader. Owned the scheduler's end-to-end design: data model, scan-claim-dispatch pipeline, garbage collection, failure recovery, and at-least-once delivery with idempotent re-evaluation. Contributed to the ledger component and defined the ingestion/dispatch contracts integrating the scheduler with the decisioning pipeline. Verse — Long-Form Content Platform Designed the backend and end-to-end flow for a modular, partly server-driven platform that lets product teams ship content-rich experiences (FAQs, terms & conditions, education pages) without building custom UI each time. Architected it for multi-tenant use across PayPal, Venmo, and Xoom via a shared core with tenant-specific modules, driving content and predefined design-system templates from the server. Designed context-aware rendering (locale, auth state) and network-aware caching for offline access and performance. Built the backend for the admin tool and defined the client SDK contract — single-call integration, deep-linkable pages, and multiple presentation modes — with Datadog observability across the content lifecycle.

Software Engineer 3 at PayPal, Apr 2022 - Feb 2025 · 2 yrs 11 mos, Bengaluru, PayPal Communications — Communications Platform Architected and own the end-to-end backend powering all PayPal communications — push, notification center, critical and silent alerts — across PayPal, Venmo, and Xoom. Built Beacon, a company-wide web portal to schedule and manage communications, from data model to UI. Re-architected the platform to act as a producer of intent objects, so every send/suppress/defer decision is centrally evaluated against eligibility, scoring, caps, and quiet hours. Drove a platform revamp for scalability, multi-region support, and integration with the centralized decisioning layer. Server-Driven UI (SDUI) Platform Led the backend for an in-house server-driven UI platform, built from scratch, serving 1B+ requests/day across iOS, Android, and Web. Architected core services: version management, page inheritance, schema versioning, and data model — enabling consistent UI delivery across all platforms.
