System development, integration & API work
When off-the-shelf doesn’t cut it — we build it.
Custom web applications, system integrations, API development, and middleware for agencies whose clients have outgrown SaaS templates and plugin stacking. Real engineering, properly scoped, properly delivered.
When agencies bring us in
Three signals you need real engineering, not another plugin.
Your client outgrew SaaS.
The off-the-shelf tool doesn’t bend the way their workflow needs. They’re paying for 5 SaaS products that don’t talk to each other. They need one custom system.
Two systems need to talk.
Their CRM, accounting, fulfilment, and website are all working but in silos. Manual data re-entry every day. They need a proper integration layer.
Manual processes are killing scale.
Spreadsheets, email approvals, copy-paste between portals. Their team’s growing but admin overhead’s growing faster. Custom tooling pays for itself in months.
What we build
Custom systems, integrations, and APIs.
Custom web applications
Internal tools, customer portals, booking platforms, dashboards. Built for the actual workflow, not bent into a generic CMS or SaaS template.
REST & GraphQL API development
Build a clean public or internal API for your client’s product. Versioning, auth, rate limiting, OpenAPI docs. Or wrap their legacy system in a modern interface.
Third-party API integration
HubSpot, Salesforce, Xero, MYOB, Shopify, Stripe, Twilio, SendGrid, Mailchimp, Klaviyo. Two-way sync, webhook handling, error retry, monitoring — production-grade, not duct-taped Zapier.
Middleware & orchestration
When five systems need to talk and none of them speak the same protocol. Custom middleware that translates, queues, retries, logs, and keeps your client’s data flowing reliably.
Webhook & event systems
Receive, validate, queue, and act on events from any system. Idempotent handling, dead-letter queues, retry logic, alerting on failures. The boring infrastructure that makes everything else work.
Headless & decoupled backends
WordPress as a headless CMS feeding a Next.js or Nuxt frontend. Or a custom Laravel/Node API serving any frontend your team builds. Clean separation, scalable architecture.
Tech stack
What we build with.
We pick the right stack for the problem, not the trendy one. Mature, well-documented, hire-able tools your client (or their next dev) can maintain.
Backend
PHP (Laravel, WordPress, vanilla), Node.js, Python (Django/FastAPI). MySQL, PostgreSQL, MongoDB, Redis.
Frontend
React, Next.js, Vue, Nuxt, Alpine.js. Tailwind. Vanilla JS where appropriate. Web Components for embeds.
Infrastructure
AWS, DigitalOcean, Cloudflare, SiteGround, Kinsta. Docker. GitHub Actions / Bitbucket Pipelines for CI/CD.
Custom build FAQ
How custom engagements work.
How do you scope custom dev work?
Discovery call → written scope doc → fixed-fee quote (or T&M ceiling) before any code. We break the build into 1–2 week milestones with deliverables you can demo to your client. No “it’ll be done when it’s done.”
What if my client doesn’t have a clear spec?
We do the spec. A small discovery engagement (typically 1–2 weeks) produces user flows, technical architecture, integration map, and scoped milestones. Your client owns the spec at the end. Whether they build with us or someone else is up to them.
Can your code be maintained by another developer later?
Yes — that’s the whole point. Documented, conventional patterns, mature framework choices, no obscure dependencies. README that explains setup, architecture, and gotchas. Any competent dev should be able to run it locally within an hour of cloning.
What about ongoing support after go-live?
Three options. (1) Hand-off entirely — you or your client take it over. (2) Bug-fix retainer — small monthly fee for any post-launch issues. (3) Active development retainer — we keep building features each month. Most clients pick option 2 or 3 because the system grows.
Will you white-label this work too?
Yes. Same model as the rest of our agency partnership work — invisible delivery, your repo, your hosting, no Web Champion mentions anywhere. Your client only ever sees your agency.
How do you handle integration testing?
Sandbox accounts for every third-party (Stripe test mode, Salesforce sandboxes, etc.) before touching production. Integration test suite for critical flows. Webhook replay tooling. Staged rollout to production with monitoring. We don’t push integration code straight to live and hope.
