Strong backend expertise with Node.js + NestJS (or similar) and TypeScript.

Solid front-end experience with React (hooks, state management, performance

optimization).

MongoDB schema design, indexing and query optimization experience.

Hands-on experience with containerization (Docker) and Kubernetes (deployment,

What to Include in Your Application

1. GitHub / portfolio / deployed product links demonstrating recent work.

2. Short case study (1 page) of one microservices project you led: problem, architecture

(service boundaries, messaging, deployment), your role, challenges and measurable

outcomes (latency, throughput, uptime, delivery time).

KPIs / Success Measures

Time to deliver production features and microservices (velocity & quality).

Service reliability: uptime, error rates and mean time to recovery (MTTR).

Performance improvements (response time, throughput) and reduced incidents after

refactors.

Test coverage and CI/CD health. Mentorship impact and team quality (code review

metrics, onboarding success)
