01.About Me

A brief introduction.

Software engineer with 1.5+ years of production fintech experience at Lentra, engineering distributed credit decision pipelines on AWS that serve concurrent financial transactions at scale.

My work spans high-throughput microservices, API design, and backend systems where sub-100ms latency and data integrity are production requirements — not aspirational goals.

Currently completing an M.S. in Computer Science at Stevens Institute of Technology, with coursework in security, distributed systems, and network infrastructure.

→ Based in Hoboken, NJ. Open to relocation.

02.Where I've Worked

Experience building production systems.

Shipping real infrastructure — not just code on GitHub.

  1. Software Engineer · Lentra

    Production
    Pune, India

    // Fintech SaaS · Distributed Systems · AWS Production

    • Optimized Java Spring Boot microservices within a distributed AWS architecture, reducing API latency by 25% across high-volume financial transaction workflows handling concurrent production traffic.
    • Integrated Python-based analytical services into credit decision pipelines, automating data ingestion into the rule engine and reducing loan processing time by 2 days while improving system throughput.
    • Strengthened production reliability by redesigning the JUnit testing framework, increasing coverage from 46% to 85% and preventing regression failures in critical backend services.
    • Implemented CI/CD pipelines using Jenkins and Git for two client-facing systems, using AWS CloudWatch to guarantee fault-tolerant releases and reduce deployment failures by 20%.
    • Built a fault-tolerant internal Node.js service automating financial reporting pipelines with event-driven scheduling and secure FTP transfers, saving 4+ hours of manual work weekly.

  2. Software Development Intern · Blitz Jobs

    Mumbai, India

    // Mobile · Java · Firebase

    • Boosted sales partner engagement by 30% by designing and launching a rooftop-solar Android app using Java, XML, and Firebase Realtime Database.
    • Leveraged REST APIs to connect the mobile application with the company's CRM backend, enabling real-time synchronization of lead and client data and driving a 10% increase in sales.
    • Enabled in-app analytics dashboards using Firebase Analytics, reducing manual KPI reporting time for the sales team by 40% and enabling immediate identification of underperforming sales territories.
