Common questions.

Got questions? We've got answers. Reach out if you don't find yours.

We primarily work with Node.js (Express, Fastify), Python (FastAPI, Django), Go, and Java Spring Boot. For databases we cover PostgreSQL, MySQL, MongoDB, Redis, and Elasticsearch. We're cloud-agnostic and work across AWS, GCP, and Azure.

A basic REST API with auth can be ready in 2–3 weeks. Full-scale microservices platforms typically run 2–6 months depending on complexity. We provide detailed timelines in our proposal before any work begins.

Absolutely. We sign NDAs, IP transfer agreements, and data processing agreements before any project kick-off. Your code and data remain 100% yours at all times.

Yes. Plans can be upgraded at any time with prorated billing. Downgrading is possible at your next billing cycle. We also offer flexible month-to-month contracts for ongoing maintenance.

Every project includes a 30-day post-launch support period. We also offer retainer packages for ongoing maintenance, feature development, and monitoring. You'll receive full documentation and code ownership.
