GraphQL Developer Sri Lanka — Senior Consultant for Production-Grade APIs
Schema-first design, federation, caching, and observability to ship faster without breaking clients.
Book a consultationIf you’re searching for a GraphQL Developer in Sri Lanka who can do more than “make queries work,” you’re in the right place. I’m a senior GraphQL consultant focused on building API layers that stay stable as teams, services, and product requirements evolve. That means clean schema design, predictable breaking-change management, and resolver implementations that perform under real traffic—not just in a demo.
I help product and engineering teams design and deliver GraphQL APIs using Node.js/TypeScript, Apollo Server, and modern tooling such as persisted queries, dataloader patterns, caching strategies, and schema registries. For larger systems, I implement Apollo Federation and service boundaries that reduce coupling, improve ownership, and keep releases independent. I also work with existing REST and microservice backends, creating a GraphQL gateway that unifies data access while maintaining sensible authorization and audit trails.
Quality and reliability are non-negotiable. I set up pragmatic testing (schema validation, contract checks, resolver unit tests), performance profiling (N+1 detection, query cost analysis), and observability (tracing, error budgets, field-level metrics) so your team can iterate confidently. Security is built in: role-based access, input validation, rate limiting, and safe introspection policies for production environments.
Engagements can be advisory (architecture reviews and roadmaps) or hands-on delivery (implementation, refactoring, and mentoring). If you need a senior consultant in Sri Lanka who can align stakeholders, guide best practices, and ship working code quickly, let’s talk.
What you get when you hire a senior GraphQL consultant
Schema design that scales
Clear domain modeling, naming conventions, and versioning strategy to prevent schema sprawl and reduce breaking changes.
Federation & microservice alignment
Apollo Federation setup, subgraph boundaries, and composition workflows that enable independent teams to ship safely.
Performance & cost control
Resolver optimization, caching, batching, and query complexity limits to keep latency low and infrastructure spend predictable.
Security, governance & observability
AuthZ patterns, audit-friendly practices, and monitoring/tracing so issues are caught early and fixed with confidence.
“We brought him in to stabilize our GraphQL layer and the impact was immediate—fewer incidents, faster feature delivery, and a schema the whole team could reason about.”
Frequently asked questions
- What types of GraphQL work can you take on as a senior consultant?
- I handle end-to-end delivery: schema design, resolver implementation, federation architecture, performance optimization, and production hardening. I can also run architecture reviews, create a migration plan from REST to GraphQL, and mentor your team on best practices and tooling.
- Can you improve an existing GraphQL API that’s slow or unstable?
- Yes. I typically start with profiling to identify N+1 patterns, expensive fields, and cache misses, then apply batching, caching, and query cost controls. I also add observability so regressions are detected early and fixes are measurable.
- Do you work with Apollo Server, Federation, and TypeScript?
- Yes—Apollo Server and TypeScript are common in my engagements, and I’ve implemented Federation for multi-team and multi-service environments. If you’re using alternative stacks, I can still apply the same principles around schema governance, performance, and security.
- How quickly can you start and what does onboarding look like?
- In most cases I can start within 1–2 weeks depending on scope. Onboarding begins with a short discovery call, access to repos/observability dashboards, and a prioritized plan for quick wins plus a longer-term roadmap aligned to your release cycle.
