Q: How much does it cost to build an enterprise backend?
A: Backend engineering runs project-based for builds such as an API platform or a microservices decomposition, as a dedicated backend team for ongoing development, or as a Fractional CTO engagement if you need architecture leadership rather than a full team. Cost depends on system complexity, integrations, throughput targets, and compliance requirements — we scope it in a free architecture consultation and give you a detailed fixed estimate, no obligation.
Q: How long does it take to build a production-ready backend?
A: A production-ready backend for an MVP typically takes 8-12 weeks, covering API design, database schema, authentication, CI/CD, and observability. We shipped a complete production MVP in 10 weeks for WorkHire, including its backend services. Larger microservices platforms with multiple integrations usually run 4-6 months delivered in incremental releases.
Q: Should I use Node.js or Java/.NET for an enterprise backend?
A: Node.js is the stronger choice for I/O-heavy workloads such as APIs, real-time systems, and event-driven services, and it lets full-stack JavaScript teams move faster with one language across the stack. Java and .NET remain sensible for CPU-bound processing or organizations already standardized on those ecosystems. Our founder Deepak Jha has 15+ years with Node.js and used it to scale LiveHindustan.com from crashing at 5M to serving 60M+ monthly users, so we recommend Node.js with NestJS when performance at scale and development speed both matter.
Q: Microservices or monolith: which architecture should my startup choose?
A: Start with a well-structured modular monolith and extract microservices only when team size, deployment independence, or scaling hotspots demand it. Premature microservices add network, observability, and DevOps overhead that slows small teams down. We design monoliths with clear module boundaries (typically NestJS modules) so extraction later is a refactor, not a rewrite.
Q: How do you design APIs that other teams can actually build on?
A: We design contract-first: OpenAPI or GraphQL schemas are written and reviewed before implementation, with consistent versioning, pagination, and error conventions. Every API ships with generated documentation, authentication baked in (OAuth2/JWT), and rate limiting at the gateway. This lets frontend, mobile, and partner teams build in parallel against a stable contract.
Q: Which database should I choose: PostgreSQL, MongoDB, or Redis?
A: PostgreSQL is our default for transactional systems because of its reliability, relational integrity, and JSON support. MongoDB fits document-heavy or rapidly evolving schemas, and Redis handles caching, queues, and session state rather than acting as a primary store. Most production systems we build combine PostgreSQL as the source of truth with Redis for caching, and we make the call based on your query patterns, not fashion.
Q: Can you build a backend that handles millions of users?
A: Yes. Deepak Jha, our Technical Lead, re-architected LiveHindustan.com for HT Media when it was crashing at 5M monthly users and scaled it to 60M+ monthly users. We apply the same playbook: horizontal scaling, multi-layer caching, query optimization, queue-based load leveling, and load testing before launch rather than after an outage.
Q: Who actually works on my backend project?
A: A typical backend engagement pairs 2-4 senior Node.js/NestJS engineers with a DevOps engineer and, where needed, a database specialist. Every project runs under our Guardian model: Deepak Jha, Technical Lead with 15+ years of experience, reviews the architecture and every release before it ships. You get direct access to the engineers, not an account-manager buffer.
Q: How do you work with backend teams in the US, UK, or UAE?
A: We are headquartered in New Delhi, India, and run remote-first with deliberate timezone overlap: US EST/PST, UK GMT, EU CET, and UAE GST clients all get daily overlap hours for standups and pairing. Current backend clients span the US, UK, Europe, UAE/Dubai, Australia, and Canada. Communication runs through your Slack, your Jira, and weekly demos, so the team feels in-house.
Q: Who owns the backend code and infrastructure you build?
A: You do, 100%. All source code, infrastructure-as-code, API designs, and documentation are your intellectual property from day one, and we sign an NDA as standard before any technical discussion. Repositories live in your GitHub/GitLab organization and cloud accounts stay in your name, so there is no vendor lock-in.
Q: What happens to the backend after launch?
A: We offer post-launch maintenance covering monitoring, security patching, dependency upgrades, performance tuning, and incident response with defined SLAs. Many clients continue with a smaller retainer team or move to a Fractional CTO arrangement for ongoing architectural oversight. We also do structured handovers with documentation and pairing if your in-house team takes over.
Q: Why hire a backend agency instead of in-house engineers?
A: Hiring a senior backend engineer takes 3-6 months and $150K+ per year in most US and EU markets, before you have architecture leadership. An agency team gives you a working senior team plus architect review in weeks, and you can scale it down after launch. The best pattern we see: we build and stabilize the platform, then help you hire and onboard your in-house team onto it.
