Ayush Kumar — Software Engineer

Migrated search from Algolia to an in-house Elasticsearch platform — search APIs in Go, data sync pipelines in Ruby on Rails. Removed a third-party dependency, cut annual operating cost by ~$200K, and improved conversion 8–10% while keeping search low-latency and highly available.

Built a real-time demand control microservice in Go and Redis to regulate order flow during peak traffic and prevent outages. Designed REST APIs for 10K+ concurrent requests and added observability with Prometheus, Grafana, Loki, and Datadog for zero-downtime deploys and fast incident response.

Developed reusable code libraries to speed up future feature delivery and reduce time-to-market for new development work.

Integrated OpenAI models into a micro-frontend architecture, enabling AI-driven user interactions across multiple backend applications — led the full integration from API design to frontend implementation.

Built and published an Angular 17 + Kendo UI component library as an internal npm package, cutting UI development time 70% and becoming the org-wide standard.

Contributed to backend architecture and led sprint execution for a $400K government-scale data synchronization platform serving Oslo Municipality, achieving 99.9% uptime with secure, fault-tolerant data exchange.

Spearheaded backend migration from .NET Framework to .NET 6 and redesigned the architecture with modern patterns — 95% performance improvement, enhanced scalability for 2x user growth.
