About Danish Mehra
I build and modernize systems at scale — from high-traffic REST APIs handling 250K–3M requests/day in a legacy monolith to greenfield event-driven microservices on Azure. At CatalystOne, I\'ve spent 5+ years owning features end-to-end across both worlds — optimizing concurrent APIs serving third-party integrations on the monolith side, while architecting webhook delivery systems, data import pipelines, and cloud-native services from scratch on the microservices side. I care about clean architecture, production readiness, and helping junior engineers grow into independent contributors. Currently exploring opportunities in distributed systems, cloud-native platforms, and data-intensive applications.
Experience
Software Engineer
May 2021 — Present · Sahibzada Ajit Singh Nagar, IN
Replaced synchronous HTTP integrations with a dual-queue asynchronous pipeline using Azure Service Bus and JMS — with auto-retry, dead-letter handling, and real-time observability for multi-tenant event delivery. Built a server-side Excel parsing engine with field-type validation and a React stepper UI — enabling teams to batch-process records without engineering intervention. Improved API reliability across high-traffic resources by implementing structured error handling, internal status codes, and concurrent request optimizations. Implemented a position selector dialog with criteria filters, error-state handling, and bulk title resolution across employee restructuring workflows — enabling admins to filter and reassign positions at scale. Leveraged AI-assisted development to accelerate feature delivery, coordinating AI-generated code with manual security and access control logic while maintaining quality through iterative review. Won CatalystOne Security Hackathon 2025 (Web Security, API Security, AI Security); applied learnings in production — implementing access control filters, CORS hardening, and secrets management.
