Custom Development & Automation

When off-the-shelf doesn't fit.
Custom builds at edge-grade scale.

Cloudflare Workers, API integrations, internal SaaS tools, workflow automation. We don't pitch from theory. We built the CORE platform suite and 7 free diagnostic tools you're free to inspect right now. The portfolio is the proof.

Scope.

Architecture review, technical assessment, fixed-fee or hourly proposal with concrete deliverables and a real timeline.

Build.

Ship the work to production. Tested, documented, deployed. Code is yours, not held hostage in a black-box repo.

Hand off.

Clean ownership transfer with documentation. Optional ongoing maintenance for builds touching live infrastructure.

The portfolio is the case study.

Most agencies pitch capabilities. We point at things we built. Every platform below is a production system running real workloads at TheBRHub. You can inspect the free tools live at thebrhub.com — they're built on the same stack we'd use for your project.

What we build

Edge-grade infrastructure. Specialized tooling. Pragmatic builds.

We're deepest on Cloudflare's edge stack and serverless architecture. We don't take projects outside our wheelhouse — better to refer you to a specialist than half-deliver.

Cloudflare Workers & edge APIs

Custom edge functions, API gateways, webhook routers, request transformations. D1 for relational data, KV for caching, R2 for object storage, Durable Objects for stateful workloads. Sub-50ms response times globally.

API integrations & middleware

Connect platforms that weren't meant to talk to each other. CRM-to-billing, ESP-to-analytics, support-to-product. Built as Workers (lightweight, no infrastructure to manage) or as full middleware where complexity demands it.

Internal tools & admin dashboards

Operations dashboards, customer support tools, internal admin panels. Built with the same SPA architecture that runs our DeliverCORE and ShieldCORE dashboards. Modern, fast, no React-bloat unless the use case demands it.

Workflow automation

Replace 3-5 Zaps with one solid integration. Custom webhooks, queued processing, retry logic, observability. The thing nobody owns at your company that breaks every six weeks — we own it properly so it stops breaking.

Architecture & advisory

Technology selection, vendor evaluation, second opinions on architecture decisions. 2-hour minimum at $250/hr. Useful when your in-house team needs senior input or you're evaluating a major build-vs-buy decision.

Migration & modernization

Lift legacy workloads off aging VPS infrastructure onto serverless edge. We're doing this for our own SiteCORE platform right now (PostgreSQL → D1 with writeThrough pattern). The same playbook applies to your environment.

How a build works

Three steps. No agency overhead.

Most custom dev shops put you through 4 meetings and a discovery phase before quoting. We scope on the first call, send a fixed-fee proposal within 48 hours, and ship within weeks instead of quarters.

1
Same day

Scoping conversation

15-30 minutes. You describe the build, we ask the architecture questions, we tell you if it's in our wheelhouse. If it's not, we recommend a better-fit specialist. No fake yes's.

2
48 hours

Written proposal

Fixed-fee SOW for project work, or hourly engagement letter for advisory. Defined scope, deliverables, timeline, payment schedule. Nothing ambiguous, no surprise charges mid-build.

3
2-8 weeks

Build, ship, hand off

Most builds ship in 2-8 weeks depending on scope. You get the code, the documentation, the deployment, the access. Optional ongoing maintenance retainer for builds that touch your live infrastructure.

FAQ

Common questions about custom development.

Deepest expertise: Cloudflare Workers, D1, KV, R2, Durable Objects. JavaScript/TypeScript primary. Vanilla JS SPAs for internal tools, React when the use case demands it. Node.js for any non-edge workloads. We also work with PostgreSQL, traditional REST APIs, and webhook-based integrations. We don't do mobile-native development, native desktop apps, or low-level systems work — better referred elsewhere.
Both. Look at the ShieldCORE dashboard or DeliverCORE app for examples of our front-end work. We default to vanilla JavaScript SPAs because they're faster and easier to maintain than React for internal tools. When you need React specifically (component reuse across multiple surfaces, complex state management), we build that too. We don't do pure design work — we'd recommend a designer for that and integrate with their output.
Both options exist. Most clients take hand-off and run the code themselves with their internal team. We provide documentation, deployment access, and 30 days of post-launch support included in every build. For ongoing maintenance, project-based ($200/hr ad-hoc) or maintenance retainer ($1,500-$3,000/mo depending on system complexity). We don't force the retainer.
Yes for practical applications. OpenAI/Claude/etc. API integrations into workflows, RAG implementations, AI-assisted classification or extraction tasks. We're skeptical of "AI for the sake of AI" projects where the value-add isn't clear. If you have a real use case (automating classification, content generation pipelines, semantic search), we'll build it. If you're chasing the hype, we'll tell you that on the call.
Workflow automation: 2-4 weeks. Worker/edge API builds: 2-6 weeks. Internal tools/dashboards: 4-10 weeks. Full SaaS-style internal applications: 8-16 weeks. Timeline depends on complexity, integration count, and how clear the scope is up front. Vague scopes always take longer — we'll push you to nail down requirements during scoping precisely so the timeline stays honest.
Both. Workflow automation and clearly-scoped builds: fixed-fee. Exploratory work, research, advisory: hourly. We'll usually scope a fixed-fee proposal after the first call once we understand the requirements. Fixed-fee aligns incentives correctly — we don't make more money by dragging out the project, you get cost certainty.
You do. Every project includes full code transfer, repository handoff, and deployment documentation. We don't believe in vendor lock-in through opaque codebases. Any developer should be able to pick up what we built and continue working on it. We use industry-standard practices (clear file structure, comments, README, deployment scripts) so the handoff is real, not symbolic.
For the 7 free diagnostic tools at thebrhub.com, the front-end code is fully visible in your browser's dev tools. They're production systems. For our paid platforms (DeliverCORE, RampCORE, VerifyCORE, etc.), the source is proprietary, but we can walk through architecture decisions and patterns on the consultation call. Past client work is generally not shareable due to confidentiality, which is the same standard we'd apply to your project.

Have a build in mind?

Book 15 minutes. Describe the project. We tell you whether it's in our wheelhouse, scope it on the call, and follow up with a written proposal within 48 hours. Real timelines, real numbers, no agency overhead.
