About

Software Development Engineer focused on building scalable, cloud-native backend systems and distributed architectures that perform reliably at enterprise scale. My work spans real-time messaging platforms, file management systems, and high-throughput audit pipelines, primarily using SpringBoot, Python, and AWS. At Veersa Technologies, I’ve led end-to-end design and delivery of systems handling multi-participant communication, event-driven workflows, and large-scale data ingestion. I’ve modernized legacy architectures into resilient cloud platforms—cutting latency, improving throughput by multiples, and enabling long-term scalability and compliance. I value clean system design, measurable impact, and strong technical ownership, and I’m comfortable driving execution across backend, cloud, and cross-functional teams. I enjoy solving hard engineering problems, especially around distributed systems, performance optimization, and reliability, and I’m always looking to learn from strong engineers and thoughtful system builders. If you’re interested in backend engineering, AWS-scale systems, or building robust products from the ground up, feel free to connect—always open to meaningful technical conversations and collaboration.

Software Engineer

Sep 2023 – Present · 2 yrs 7 mos · Noida, Uttar Pradesh, India · Hybrid

Messaging360 Microservice | Angular · SpringBoot · Socket.io · AWS SQS · EKS · S3
Architected a multi-participant messaging microservice enabling secure communication across Payer, Provider, Patient, and Caregiver personas, with granular business constraints for message eligibility.
Assembled backend conversation orchestration in Java supporting multiple users and groups per conversation, with structured flows across Conversations, Messages, Subscribers.
Filestream Modernization | Python · AWS Lambda · API Gateway · DynamoDB · S3
Refactored legacy .NET Lambda-based file APIs to eliminate cold starts and fragmented workflows by introducing Python-based bulk upload/download APIs, centralizing validation, quota checks, and presigned URL generation into a single request, cutting end-to-end upload latency by ~60%.
Activated bulk file operations with partial success handling, supporting 100 files per request over sequential uploads and yielding a 5× throughput improvement with smoother UI behavior during large file interactions.
Executed migration to a secure, scalable cloud storage architecture using S3 for file storage and DynamoDB for metadata, aligning cross-team rollout and phased synchronization from legacy EC2 + SQL systems and lowering storage-related incidents by ~40%.
AuditTrail Modernization | AWS Kinesis · Firehose · Lambda · OpenSearch · Debezium · ECS · EMR Jan 2025
Spearheaded the design and implementation of a near real-time, cloud-native audit tracking platform, replacing a fragile SQL trigger + CDC-based system that failed beyond 3–5M records/table and could not scale for 7-year compliance retention with 3TB+ monthly data growth.
Devised a high-throughput ingestion pipeline using Kinesis Data Streams, Firehose, and Lambda, handling column-level before/after audit diffs and delivering ~10× higher ingestion scalability over legacy Service Broker and CDC consoles.

SFTP Module — Crafted UI for vendor SFTP configuration with password-based and public–private key authentication on JSCape Server, enabling secure transfers and shrinking onboarding time by ~30%.
Audit History npm Library — Strengthened a shared audit-history UI npm library across applications in a monorepo setup, improving component reuse, visual consistency, and reducing duplicate UI effort.
Filestream MVC — Constructed an MVC-based monitoring UI for file-sync visibility between SQL + EC2 and DynamoDB + S3, accelerating resolution by ~40% and removing ~25% false-positive alerts.
