Experience at QuadB Technologies
During my time at QuadB Technologies (Division kaiFoundry), I’ve worked across backend development, system optimization, and infrastructure automation. My work has focused on improving reliability, performance, and developer experience for systems that handle financial transactions and high-volume traffic.
Here are the key areas where I contributed:
1.
Secure system design
Designed and built an encrypted endpoint routing system used for financial transactions. It improved backend reliability, tightened API security, and reduced exposure of sensitive routes.
2.
SEO engineering with Go
Introduced an SEO-friendly React setup by creating a lightweight Go proxy server to generate dynamic meta tags, enabling accurate social media previews for dynamic pages.
3.
Microservice migration
Migrated three monolithic backends into Node.js (Express) and Spring Boot microservices, integrating Redis caching to boost API response times by 30–40% and support 10K+ daily requests.
4.
Fixing performance bottlenecks
Took ownership of a backend suffering from heavy database failures. Replaced nested manual queries with ORM-driven optimized queries, resolving bottlenecks and stabilizing the system.
5.
CI/CD automation
Built a complete CI/CD pipeline that replaced manual deployment steps and reduced production deployment time by more than 80%.
6.
Backend development & documentation
Developed scalable RESTful APIs and backend services in Node.js and Spring Boot, documented system workflows, and containerized services with Docker to simplify deployments and eliminate dependency issues.
