I build scalable, cloud-native applications — transforming complex business requirements into secure, resilient, and cost-efficient solutions.
From idea to production, at scale
End-to-end engineering across cloud, backend, and frontend.
Cloud Architecture
Designing highly available, DR-ready AWS infrastructure with security and cost-efficiency built in from day one.
Full Stack Development
Building end-to-end MERN applications — from responsive React UIs to robust Node.js microservices and APIs.
Contact Center Engineering
Integrating Amazon Connect, Cisco UCCE, Webex, and Genesys into unified, automated CX platforms.
Operational Excellence
Server management, SQL optimization, and CI/CD pipelines that keep systems fast, secure, and reliable.
Engineering scalable systems, end to end.
I'm a Software Developer at Consilium Software, where I bridge complex backend logic with intuitive user experiences. My journey started with writing simple code — today I architect entire ecosystems that power enterprise-grade communication platforms.
Specializing in AWS Cloud and the MERN Stack, I don't just build applications — I engineer scalable solutions. From optimizing serverless functions for Amazon Connect integrations to architecting systems for high-traffic environments, I make sure every solution is robust, secure, and cost-efficient.
Beyond development, I'm deeply invested in Operational Excellence — managing Windows Servers, fine-tuning SQL databases, and implementing AWS cost-saving strategies. I'm dedicated to continuous learning, always exploring emerging technologies.

Showing all 5 projects
Unified Contact Center Orchestration Layer
Centralized orchestration platform integrating Cisco UCCE, Webex Contact Center, Genesys, and Amazon Connect — enabling provisioning automation, real-time monitoring, reporting aggregation, campaign execution, and CRM integrations through a single control plane.
Distributed Outbound Dialing & Campaign Engine
High-volume outbound system supporting agentless, predictive, and progressive dialing across UCCE and Genesys, with Amazon Connect extensions. Implemented distributed SQL schedulers, concurrency controls, retry strategies, and cross-machine coordination for horizontal scalability.
Advanced IVR Flow Designer & Execution Framework
Production-grade IVR design studio with drag-and-drop flow creation, version control, hierarchical node linking, and execution JSON generation for Cisco UCCE, UCCX, and enterprise IVR systems. Enabled dynamic routing, skill-group transfers, transaction tracking, and real-time config updates.
Real-Time Omnichannel Interaction Engine
WebSocket-based messaging platform handling chat and email routing with sticky-agent logic, skill-based assignment, business-hour enforcement, SLA controls, and supervisor quality monitoring. Integrated IMAP/SMTP processing, transcript analytics, and CRM synchronization.
Secure Multi-Region Cloud Architecture & Marketplace Enablement
Highly available multi-AZ and DR-ready AWS deployments with Route 53, WAF, ALB, ACM, VPC endpoints, Secrets Manager, and KMS. Led AWS Marketplace product listings, APN alignment, cost optimization, and Well-Architected implementations for enterprise clients.
Let's build something that scales.
Have a project in mind?
Whether it's a cloud migration, a new platform, or a tricky engineering challenge — I'd love to hear about it. I usually respond within a day.
