Backend quality determines whether your product survives growth. As a Node.js developer and lead software engineer in Nepal, I design Express and NestJS services, messaging pipelines, and data layers that stay predictable under load.

What you get

✓REST and GraphQL API development
✓NestJS and Express microservices
✓MongoDB / PostgreSQL schema and query optimization
✓Redis caching and session strategies
✓Kafka-based async processing and notifications
✓AWS deployment, Docker, and observability hooks

How engagement works

Step 01

Domain & API design

Define bounded contexts, contracts, and failure modes before scaling complexity.

Step 02

Implement & isolate

Build services with clear ownership of data, auth, and side effects; add queues where needed.

Step 03

Load-aware hardening

Profile hot paths, add caching, and document operational runbooks.

Outcomes

APIs that remain stable as clients multiply
Async workloads that do not block user-facing requests
Backends your team can debug and extend

Service FAQs

Express or NestJS?

Express for lean services; NestJS when structure, DI, and larger team scale matter. I use both.

Can you integrate with existing frontend teams?

Yes. I publish clear API contracts and collaborate closely with React/Next.js developers.
