Service — API design & integrations
APIs other teams can build on.
An API is a promise you have to keep for years. We design them so the second consumer does not force a rewrite, and integrate the ones you do not control so their bad days stay their bad days.
01 / 3
API design and contracts
The interface is the part you cannot quietly change later. It deserves the design time.
REST or GraphQL shaped around the domain, specified before implementation, and versioned so existing clients keep working.
- Schema-first specs reviewed before a line of handler code
- Explicit versioning and deprecation windows
- Generated clients and documentation from the same source

Third-party integrations
Every external system will be slow, wrong, or down at some point. Design for that and it becomes routine.
Payment providers, CRMs, logistics, identity — connected with retries, idempotency, and reconciliation so a partner outage does not corrupt your data.
- Idempotency keys and replay-safe handlers on every write path
- Backoff, circuit breaking, and dead-letter handling
- Reconciliation jobs that detect and repair divergence

Service-to-service communication
Microservices only help if the contracts between them are stricter than the ones inside them.
Internal boundaries, events, and queues defined so services can be changed independently instead of released as one lump.
- Event schemas registered and validated at the boundary
- Queues and retries sized to real throughput
- Tracing across hops so a slow request can be attributed
Engineering Principles
Three things we hold to.
How we approach every engagement — the non-negotiables that keep systems maintainable, compliant, and buildable.
Specify before you build
The contract is agreed and reviewed first. Implementation follows the spec, not the reverse.
Assume the other side fails
Timeouts, retries, and reconciliation are part of the first version, not a later hardening pass.
Documentation is generated
Docs come from the schema so they cannot drift away from what the API actually does.
Engagement Outcomes
Production deliverables you own from day one.
Every engagement produces tangible codebases, automated pipelines, and operational specs your internal team actually runs.
Production Web Architecture
Full TypeScript React/Next.js product application built with strict schema validation, responsive state, and role-based permissions.
- Clean Git history with semantic commits
- Full end-to-end runtime & type safety
- Edge-optimized data fetching & caching
Enterprise Component Library
Documented component system enforcing consistent typography, spacing, accessible color contracts, and micro-interactions.
- WCAG 2.1 AA accessibility compliance
- Storybook / isolated component docs
- Zero-runtime CSS token architecture
Core Web Vitals Harness
Automated performance instrumentation guaranteeing sub-second load times and distributed real-user monitoring.
- Strict budgets: LCP < 0.9s & INP < 150ms
- Automated Lighthouse regression CI gates
- Real-user monitoring & error telemetry
Operational Specs & Runbooks
Comprehensive architecture blueprints, deployment guides, and structured pairing sessions for your internal engineering team.
- Self-healing production deploy scripts
- Architecture Decision Records (ADRs)
- Paired engineering team transition

Bring the constraint that worries you most. That is usually the fastest way to work out whether this is the right service for the job.
