About

Senior engineer who owns problems end to end.

I'm a Lead Software Engineer with 6+ years of experience architecting and shipping enterprise healthcare platforms, AI-driven applications, and distributed data pipelines.

I own complex problems end-to-end, from database design and API architecture to frontend performance and production monitoring. I've built systems handling 1M+ requests/day at sub-100ms response times, integrated Claude and OpenAI with structured agentic workflows, and rolled out multi-tenant platforms at scale.

My day-to-day involves Node.js, React, Next.js, and TypeScript, but I'll reach for whatever the problem actually needs: WebSockets for real-time updates, BullMQ for distributed job processing, Redis for caching, or LangGraph for AI orchestration.

What I do

  • Architect multi-tenant SaaS platforms end-to-end
  • Design scalable distributed processing pipelines (BullMQ, Redis)
  • Tune databases (MySQL) and REST APIs for sub-100ms responses under load
  • Integrate OpenAI/Claude with structured agentic workflows (LangGraph)
  • Lead cross-functional engineering squads and incident response
  • Build highly interactive and dynamic React/Next.js frontends
Core Competencies

Technical impact I can deliver.

Plain and simple: I solve complex business problems through scalable architecture and automation. Here's what I can do for you.

High-Volume Data Processing

Exporting 6M+ records without crashing.

I build highly concurrent, distributed background job pipelines using BullMQ, Redis, and Node.js that handle massive datasets efficiently, drastically reducing manual work by up to 98%.

MedImpact Healthcare Systems·Enterprise PBM Platform

Aug 2023 - Present Dubai, UAE
  • Technical Leadership & Incident Response: Lead a cross-functional squad spanning Development, QA, and DevOps, serving as a primary bridge between business and engineering. First responder for critical production incidents, performing root cause analysis, restoring services, and driving permanent corrective actions.
  • PBM Clinical-Only Solution Ownership: Owned end-to-end delivery of a PBM Clinical-Only Solution across 5 enterprise clients, taking features from requirements analysis and solution design through development, testing, release, and production deployment—reducing delivery cycles from weeks/months to as little as 1 day.
  • High-Scale Backend Engineering: Engineered high-performance Node.js services supporting 1M+ requests/day and 99.98% uptime, optimizing database access, caching, asynchronous processing, and API execution for high-volume production workloads.
  • Distributed Systems Architecture: Designed scalable distributed system architectures capable of supporting 100M+ requests/day using horizontal scaling, workload partitioning, caching, asynchronous processing, and fault-tolerant service design.
  • API & System Optimization: Optimized critical APIs from multi-second response times to sub-100ms latency, delivering 90%+ performance improvement through execution-flow optimization, database query tuning, caching, and cloud VM resource right-sizing.
  • Config-Driven Multi-Tenant Live UI Platform: Designed and built a configuration-driven, multi-tenant Live UI platform from scratch using Next.js, React, TypeScript, and Node.js—enabling teams to switch between client environments and create new pages in under 5 minutes instead of months.
  • High-Volume Data Export System: Built a data export/download system capable of reliably processing and downloading 6M+ records without application crashes, while eliminating database egress requirements and reducing cloud infrastructure costs by approximately 40%.
  • POC Processing Automation: Developed an asynchronous POC processing platform using BullMQ/Redis for Excel-based datasets, API configuration, payload templates, authentication, and live validation—reducing manual processing effort from approximately 600 hours to 6–12 hours (98% reduction).
