Which versions of MongoDB, React, and Node do your engineers use?

MongoDB 7 with Atlas managed clusters, React 19 with Server Components, Node.js 22 LTS, Express 4 or Fastify 5 depending on performance needs. TypeScript end to end on every greenfield project.

Do your MERN engineers handle real-time and WebSocket work?

Yes. Socket.IO and native WebSockets for chat, presence, live dashboards. Redis adapter for horizontal scaling, sticky sessions, room-based broadcast patterns. Sub 50ms tick latency under load.

Can your MERN engineers build serverless on AWS Lambda?

Yes. Lambda functions in TypeScript with esbuild bundling, API Gateway, EventBridge, Step Functions for orchestration, DynamoDB when it fits better than Mongo. React front end on CloudFront or Vercel.

Can your MERN engineers integrate with our existing codebase?

Yes. Engineers join your existing repo, follow your code style, use your build, your CI, and your observability stack. No tool imposition, just added capacity.

Do you also handle Postgres or other databases?

Yes. MERN is the default but we are not married to MongoDB. We move to Postgres with Prisma or Drizzle when relational guarantees matter, and we have hybrid Mongo + Postgres setups for clients who want both event-sourced and transactional flows.

How fast can a MERN engineer start on our project?

Most clients get a vetted 3-engineer shortlist in 5 business days, finish technical interviews by day 7, and have a MERN engineer pushing code by day 14. Fast-track placement in 48 hours if a bench match exists.

Who owns the code and IP?

You do. Source code is committed to your repository under your organisation account from day one. IP and copyright assignment is built into the standard SOW, no vendor lock-in.
