## Headline

Developer at heart, architect by craft — payment gateways, commercial cards, systems that don’t fail quietly\. Director @ Verifone\. Introvert who thrives with extroverts\.

## About

Portfolio : https://thedevesh\.com Payment systems fail in expensive, quiet ways — duplicate charges, settlement windows that blow past SLA, integrations that take a quarter to onboard a new bank\. I've spent 19 years building systems that don't do that\. At Verifone I lead a 10\-person team across 30\+ microservices, where we cut settlement processing from 8 hours to 45 minutes and shipped an idempotency framework guaranteeing exactly\-once transaction handling across EMEA and US\. At Fiserv I led a \~15\-person org spanning backend, web, mobile and QA on a corporate card platform serving hundreds of banks\. At SpendLabs I took a monolithic card platform to event\-driven microservices without disrupting live banking customers\. Before that, 12 years at TSYS\. A theme runs through all of it: taking bespoke engineering out of customer onboarding\. Configurable application forms for banks at TSYS, a plugin\-based issuer integration layer at SpendLabs, automated multi\-tenant file processing at Fiserv\. New customer, config change, not a project\. I work in event\-driven backends — Java, Spring Boot, Scala, Akka, Apache Pulsar, gRPC, Elasticsearch, Kubernetes on AWS — and I still write production code\. Cluster singletons across pods, Elasticsearch refresh semantics, exactly\-once processing: the unglamorous parts are usually where the money gets lost\. Developer at heart, architect by craft\. An introvert who thrives with extroverts\.

## Work experience

Director Cloud Engineering at Verifone, Mar 2025 \- Present · 1 yr 5 mos, Pune District, Lead a 10\-person engineering team owning 30\+ microservices across the payments platform\. Reduced settlement processing time by 90%, from 8 hours to 45 minutes, by re\-architecting the settlement engine for parallel processing — materially improving settlement turnaround and operational headroom\. Designed and deployed an enterprise\-grade idempotency key framework guaranteeing exactly\-once transaction processing, eliminating duplicate payment risk across EMEA and US payment ecosystems\. Introduced Built\-In Quality practices across the estate, shifting the testing strategy from unit\-test\-heavy to container\-backed integration tests using Testcontainers — catching real integration failures before release and raising confidence in deploys across 30\+ services\.

Director Software Development at Fiserv, Jun 2021 \- Mar 2025 · 3 yrs 10 mos, Pune District, Led a \~15\-person organization across backend/DevOps/SRE, Angular web, iOS/Android, and QA, delivering a cloud\-native corporate card platform for hundreds of banks across Europe and the US\. Stayed hands\-on throughout, personally designing and building core backend services in Scala and Akka\. Built the file processing services that onboarded banks and corporate customers into the platform's multi\-tenant model, ingesting partner files and provisioning accounts under the correct tenant — turning onboarding from a manual exercise into an automated pipeline\. Scaled transaction retrieval to ingest and serve millions of card transactions daily with near real\-time visibility for corporate customers, tuning Elasticsearch indexing and refresh behavior to hold query latency under load\.

Technical Director at SpendLabs, Mar 2020 \- Jun 2021 · 1 yr 4 mos, Pune District, Led the migration of a monolithic corporate card platform to an event\-driven microservices architecture, re\-architecting card issuance, account management, and transaction processing without disrupting live banking customers\. Designed the target architecture on Scala and Akka, with gRPC \+ Protobuf for service\-to\-service contracts, Apache Pulsar as the event streaming backbone, and Elasticsearch for low\-latency transaction search and real\-time analytics\. Used Akka cluster singleton actors as the backbone for ordered, single\-writer processing of transaction events across Kubernetes pods, backed by a persistent transaction store — guaranteeing deduplication and exactly\-once semantics under pod restarts and rebalancing\. Built a plugin\-based, processor\-agnostic integration layer for issuer processors, turning new issuer onboarding into a configuration exercise rather than a bespoke project — supporting end\-to\-end card issuance, activation, transaction processing, and lifecycle management\. Modeled the corporate hierarchy \(Company → Control Account → Sub\-Accounts, and Company → Individual Accounts\) using Domain\-Driven Design and CQRS, separating command and query paths to scale reads independently of writes\. Deployed on AWS EKS with zero\-downtime rollouts, horizontal scalability, and fault tolerance across the distributed cluster\.

Manager Applications System Development at TSYS, Feb 2015 \- Mar 2020 · 5 yrs 2 mos, Pune District, Managed a 10\-person team spanning backend development and automation QA\. Owned an enterprise self\-service platform that let client banks customize their own online card application forms, built on Spring Boot, Freemarker templating, and PostgreSQL — removing engineering effort from every new bank's onboarding\. Integrated TSYS Card Guard for real\-time and post\-transaction rule management, enabling dynamic fraud detection, card controls, and transaction authorization\.

Internet Software Developer Senior G2 at TSYS, Aug 2013 \- Feb 2015 · 1 yr 7 mos, Pune District, Maharashtra, India

Internet Software Developer Senior G1 at TSYS, Dec 2012 \- Jul 2013 · 8 mos, Pune District

Software Executive at Infonox \(A TSYS Company\), Feb 2008 \- Oct 2010 · 2 yrs 9 mos, Pune District
