## Headline

Tech Lead \| Senior Software Engineer \| Distributed Systems, Microservices, Kubernetes, Golang, Java \| Scaled Fintech Platforms to 18M\+ MAU

## About

I am a Tech Lead and Senior Software Engineer with 5\.5\+ years of experience building high\-scale backend platforms, microservices, and resilient infrastructure for fintech systems\. My work has focused on solving the kinds of engineering problems where performance, reliability, and execution quality directly affect business outcomes\. I have helped scale systems supporting 18M\+ monthly active users, designed automatic failover that cut switch\-over time from 15 minutes to under 10 milliseconds, reduced average latency from 50 ms to 2 ms through caching strategy improvements, and delivered observability changes that improved MTTR by 30% while cutting infrastructure spend by approximately JPY 209M annually\. Most recently, I conceived and built KaizenDev, an internal platform for autonomous background coding agents\. I own the platform across architecture, sandbox runtime design, orchestration, web experience, persistence, integrations, and Kubernetes\-based deployment\. I am strongest in backend architecture, platform engineering, distributed systems, migration programs, reliability engineering, and developer productivity\. Core strengths: Golang, Java, Kubernetes, Docker, MySQL, Redis, Elasticsearch, Terraform, OpenTelemetry, CI/CD, observability, performance optimization, incident response, and technical leadership\.

## Work experience

Technical Lead at Rakuten India, Apr 2026 \- Present · 5 mos, Hybrid, Conceived, architected, and built KaizenDev, an internal platform for autonomous background coding agents that turns repeatable engineering work into review\-driven, asynchronous workflows\. Own the end\-to\-end platform architecture across sandbox runtime design, orchestration, persistence, integrations, web UX, and Kubernetes\-based deployment\. Built a multi\-tenant execution platform where agents can clone repositories, gather context, modify code, run validations, open merge requests, and respond to feedback inside isolated cloud sandboxes\. Defined the platform direction across reusable playbooks, scheduled automation, enterprise tool integration, and centralized governance so it can scale from one\-off tasks to repeatable engineering operations\.

Senior Software Engineer II at Rakuten India, Apr 2024 \- Apr 2026 · 2 yrs 1 mo, India, Led the migration of application logs to Elastic Cloud using Terraform, ingest pipelines, and Filebeat, delivering approximately JPY 209M in annual infrastructure cost savings\. Implemented OpenTelemetry with tail\-based sampling, improving mean time to resolution by 30 percent while optimizing trace storage cost\. Improved database performance with a write\-through Redis caching strategy, reducing average latency from 50 ms to 2 ms and lowering CPU utilization\. Designed and delivered a centralized Reactive User Management Service using Quarkus, gRPC, and Mutiny, improving resource utilization by 90 percent\. Strengthened authentication flows by replacing SMS login with voice\-based phone call authentication through Vonage APIs and helped reduce fraud\. Raised engineering quality through approximately 1,200 unit tests, 80 percent test coverage, and production issue investigation including heap dump analysis and JVM tuning\.

Senior Software Engineer I at Rakuten India, Apr 2023 \- Apr 2024 · 1 yr 1 mo, India, Led the migration from a monolith to microservices, enabling the system to handle up to 800,000 requests per second and scale from 3M to 18M monthly active users\. Architected an automatic failover system based on real\-time error thresholds, reducing service switch\-over time from 15 minutes to under 10 milliseconds\. Designed and developed Golang\-based API gateways with feature flags for progressive traffic migration, enabling safer and more controlled rollouts\. Engineered a custom Golang reverse proxy that enabled zero\-downtime migration from Oracle to MySQL for critical services\. Improved deployment confidence by integrating Gatling, JaCoCo, and K6 into CI/CD pipelines\. Mentored interns building a MySQL proxy for high\-RPS query caching and contributed to on\-call incident response and root cause analysis for critical production issues\.

Blockchain Developer at Tata Consultancy Services, Jan 2020 \- Mar 2020 · 3 mos, Trivandrum
