About

Professional summary

I am a Senior Software Engineer and published AI researcher with more than five years of experience building high-performance distributed systems, backend platforms, and production-grade AI applications. I specialize in Python and TypeScript solutions that support scalable, reliable, and secure products.

I design Generative AI workflows using LLMs, RAG, semantic search, MCP servers, and LangGraph-based agentic systems. My work includes integrating foundational models with enterprise data sources while implementing validation, compliance, and verification guardrails.

I have strong experience with asynchronous, event-driven microservices, high-concurrency transactional systems, and multi-tenant architectures. I build resilient APIs, messaging systems, automation services, and financial engines that prioritize low latency, data consistency, and observability.

I work across cloud and DevOps practices, including AWS EKS, Kubernetes, Docker, Terraform, and GitHub Actions. I create automated CI/CD pipelines and infrastructure workflows that improve release reliability, deployment speed, and platform uptime.

I have delivered solutions in healthcare, fintech, payments, job portals, food delivery, and enterprise CRM integrations. I also bring hands-on experience in testing, database optimization, authentication, and leading distributed engineering teams.

My research has been published in IEEE Access, focusing on cryptocurrency price forecasting using feature selection, bidirectional LSTM models, and trend-preserving bias correction. I am committed to applying rigorous engineering and data-driven approaches to intelligent software products.

Career history

Senior Software Engineer PegaSync

Demonstrating expertise in backend systems engineering and AI integration, this professional designs high-concurrency event-driven architectures, real-time messaging, and autonomous LLM orchestration layers using Python (FastAPI), Node.js, Socket.io, Model Context Protocol (MCP) servers, Redis, and RabbitMQ. They have delivered substantial operational impact across healthcare and logistics by implementing HL7/FHIR data transformations via Mirth Connect, custom AI verification guardrails, and route optimization engines with PostgreSQL—reducing manual labor and processing errors by up to 70%, improving delivery times by 15–20%, and accelerating emergency response by 30%. Through asynchronous queues, cron jobs, and Winston logging, they maintain sub-100ms latency and zero data loss across 5K+ simultaneous updates and 1000+ daily deliveries, while accelerating feature deployment by 40% via GitHub Actions CI/CD pipelines and mentoring mid-level engineers in distributed design and test pyramid standards.

Senior Software Engineer R-Tech USA INC

Engineered backend systems using Node.js, Laravel, and optimized MySQL/PostgreSQL databases to deliver high-concurrency performance and strict security for over 10,000 monthly users. Across multiple domains, they automated candidate matching in a job portal by integrating LLM-based parsing and custom prompt pipelines to speed up screening by ~35%, streamlined financial operations via an automated Loan Management System that cut processing effort in half, and built an event-driven notification architecture supporting 1,000+ simultaneous registrations during international events while cutting communication overhead by ~40%. By optimizing database indexing, restructuring Azure cloud storage architecture, and implementing JWT with Role-Based Access Control (RBAC), they cut query response times by up to 35%, slashed storage latency and infrastructure costs by 30–40%, and reduced unauthorized access incidents by ~40%.

Software Engineer Goodcore Software Limited

Engineered enterprise-grade backend services supporting high-stakes business workflows for major clients like Pepsi, Coca-Cola, and LinkedIn while maintaining >99.9% system uptime. They drove operational productivity by building a localized RAG-based semantic search service for CRM workflows that sped up complex text lookups by ~25%, alongside seamless API integrations across G Suite, Salesforce, Office 365, Twilio, and Zoom that cut manual coordination by ~40%. By optimizing REST APIs, database queries, Redis caching, and lazy loading strategies for large datasets, they reduced response and page load times by up to 40% while significantly easing database load. Additionally, they fortified system trust by implementing OAuth, Laravel Passport, and 2FA authentication—reducing unauthorized access incidents by ~50%—and streamlined release reliability by automating CI/CD pipelines to cut deployment errors by ~30%.
