About

I'm a Java Backend Engineer with 2 years of experience designing and building the systems behind enterprise SaaS products — from Spring Boot microservices and REST APIs to AWS-based distributed architectures.

My work centers on the hard, invisible parts of software: engineering 2 TB file transfers with resilient retry and resume, designing multi-region architectures for data residency and disaster recovery, and driving down production defects by 90% through disciplined testing.

I care about clean system design (HLD/LLD), event-driven architecture, and observability — building services that are secure, traceable, and fast under real-world load.

Software Engineer · Xcelore Pvt Ltd

Jun 2025 — Present

Noida, Uttar Pradesh

Designed and built scalable Spring Boot microservices (Java 21, PostgreSQL, Redis) powering enterprise document management, transfer, and e-signature workflows serving thousands of API requests per day.
Architected an automated workflow engine for document signing, approvals, and transfers with configurable approval chains and Signer/Approver/Viewer/CC roles, cutting manual processing effort and turnaround time.
Designed multi-region hosting architecture (HLD/LLD) for global SaaS deployments — enabling regional data residency, disaster recovery, and low-latency access across geographies.
Engineered large-file transfers up to 2 TB using S3 multipart uploads with resilient retry and resume mechanisms.
Developed RESTful APIs with optimized response times through Redis caching, asynchronous processing, and database query tuning; integrated Redis Pub/Sub for low-latency messaging across distributed microservices.
Implemented AWS cloud solutions using S3, SES, and CloudFront to improve system performance, reliability, and document delivery across regions.
Built centralized audit logging and activity tracking ensuring compliance, traceability, and operational visibility across all services.
Secured distributed workflow orchestration with real-time status tracking using JWT authentication, OAuth2, and Spring Security.

Associate Quality Analyst (Java Backend Development) · RoboMQ Pvt Ltd

Jul 2024 — May 2025

Jaipur, Rajasthan

Developed backend microservices for the Hire2Retire identity-lifecycle platform using Java, Spring Boot, and RabbitMQ, supporting real-time HR data processing.
Built RESTful APIs integrating HR systems with enterprise identity platforms, handling thousands of sync operations daily across employee onboarding, updates, and offboarding events.
Designed a scheduler microservice for identity reconciliation with 5-minute sync cycles, ensuring near real-time data consistency between source and target systems.
Improved data accuracy by 30% through automated data pipelines and scheduled processing jobs.
Reduced production defects by 90% by resolving critical issues and strengthening JUnit test coverage and integration testing.
