Why us

A design agency that actually ships production code.

Most "design + dev" shops are designers with a Squarespace license. We're designers with a real engineering team — the same people who shipped your favorite SaaS onboarding flow.

How Dinko builds apps

  • Senior engineers (no offshore hand-offs)
  • Typed code, tests, CI/CD
  • GitHub repo in your org from day 1
  • Modern stack (Next.js, Postgres, tRPC)
  • Post-launch pairing with your team

Most agencies "build apps"

  • Bubble / Webflow stitched together
  • Offshore handoffs, no code review
  • No tests, no CI, no documentation
  • You own the IP but can't read the code
  • $3,000/mo "maintenance" forever
What we build

Custom software, purpose-built.

If your workflow is leaking hours into spreadsheets, or your customers are asking for a portal, or your MVP is stuck in Figma — that's us.

Admin Dashboards

Internal tools, operations dashboards, data-viz interfaces that replace the Google Sheets your team has outgrown.

  • Role-based access control
  • Real-time metrics
  • CSV import/export

Customer Portals

Client-facing portals for scheduling, billing, document access, support. The thing your customers keep asking for.

  • Auth + SSO (Google, Microsoft)
  • Stripe / billing integration
  • Document storage + e-sign

SaaS MVPs

First version of your SaaS — designed, built, and shipped in 10–14 weeks. Real code you can raise against or grow into.

  • Auth + subscriptions
  • Onboarding flows
  • Multi-tenant architecture

API & Integrations

Middleware, webhooks, connectors. Get your CRM, ERP, shipping, and billing talking to each other.

  • REST + GraphQL APIs
  • Webhook / event systems
  • Zapier / Make extensions

Cross-Platform Apps

Web + iOS + Android from a single codebase (React Native / Expo). Ship to three platforms without three teams.

  • React Native / Expo
  • Push notifications
  • App Store / Play Store handling

AI Features

Embed Claude, GPT, or custom ML into your product — properly, not as a chatbot gimmick.

  • Claude / OpenAI integration
  • Vector search + RAG
  • Streaming UI patterns
The stack

Opinionated. Modern. Maintainable.

We use the same stack across every app so you can hire any senior dev in the market to maintain it. No obscure frameworks, no vendor-specific magic.

          Pricing

          Three engagement models. Pick your fit.

          Custom software scopes honestly. These are floors — every app is quoted after discovery. What you won't pay: hidden ongoing license fees, vendor lock-in, or surprise "deployment" costs.

          Dinko really knows the ins and outs of web design, even helping to teach me how to do complex tasks like coding for automated certificates of completion for my courses. I really appreciate him not just making the website for me, but teaching me how to manage the website myself.

          Dinko can (and does) do it all! Working directly with him on multiple brand website projects, his approach is always focused on how to deliver the best results and tackle any and all hurdles that appear along the way. He's a collaborative partner that clearly views client success as the number 1 priority. It's amazing what his unique skillset of design and development expertise bring to the table in terms of visioning and executing on first-rate web assets.

          We hired Dinko to help us a build a new website for our chiropractic clinic. He's an incredibly friendly and knowledgeable guy who brought a ton to the table right away. As we had questions, he was able to point us to all of the right place and we're incredibly happy with the finished product. I'm not sure there's anyone out there who's more of an expert on digital marketing than Dinko!

          Questions

          Real questions from actual discovery calls.

          Do we really own the code?+
          Completely. The GitHub repo is created in your organization on day one. We're just collaborators. If you want to fire us tomorrow, you hand over a deploy key and you're done. No escrow, no license fees, no vendor lock.
          Can you take over an existing codebase?+
          Yes. We do this often — usually after a founding team has outgrown offshore or Bubble. First step is always a code audit ($3,500, flat) — we read the codebase, document it, and write a remediation + roadmap doc. You can hand that doc to anyone, with or without us.
          What about ongoing maintenance?+
          Three options: (1) we hand off to your team and stay on retainer for complex issues, (2) we stay fully embedded monthly, or (3) you hire developers directly and we train them in your code. Most clients start with option 1 and graduate to 3 within a year.
          Can you work with our in-house team?+
          Yes — this is the Embedded Team model. Our senior folks slot into your Slack, Jira, and GitHub. We do code reviews with your team, pair on tricky work, and generally make your juniors better. Most useful when your team is understaffed at the senior level.
          Do you sign NDAs / IP assignments?+
          Yes, standard practice. We sign mutual NDAs at the start of discovery (often before the first call if needed), and all deliverables are full work-for-hire with IP assigned to you at delivery. Our template is available on request.
          What stack if we <em>need</em> something other than Next.js?+
          We also work in Remix, SvelteKit, Astro (for content-heavy), and Rails (for monolithic SaaS). We avoid Ruby on Rails for greenfield these days but will take it over. We do not take on PHP/Laravel, Django, or .NET projects — not because they're bad, but because they're outside our senior team's depth.
