Custom apps. Real engineering. Yours to own.
Dashboards, portals, SaaS MVPs, internal tools. Built on modern stacks (Next.js, Postgres, tRPC) with real testing, real deployments, and source code you own outright.
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
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
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.

Discovery, design, build, ship. In two-week sprints.
Bi-weekly demos, staging environment from week 3, you see progress every fortnight. No three-month radio-silent development.
Discovery
Interviews, user stories, tech-scoping. We say no to scope creep here.
Weeks 1–2Design
Hi-fi Figma, flows, state diagrams. Dev-ready specs.
Weeks 3–5Build Sprints
2-wk sprints, demos, staging. You see progress fortnightly.
Weeks 5–14QA & Hardening
Load testing, security review, accessibility audit.
Week 15Launch & Handoff
Deployment, docs, team training. Optional retainer after.
Week 16Three 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.
Interactive Figma prototype + clickable demo. For validating before you commit.
- User research
- Hi-fi Figma prototype
- Clickable demo for user testing
- Technical spec doc
- Scope + build estimate
Working product, launched. Auth, billing, core workflows. Growable foundation.
- Design + build + deploy
- Full-stack (Next.js + Postgres)
- Auth, billing, admin
- CI/CD + monitoring
- Tests + documentation
- 60-day post-launch support
Senior designer + engineer embedded with your team. Month-to-month, scale up/down.
- 1 senior designer, 1 senior engineer
- Weekly sprint cadence
- Works in your repo + Slack
- Scale team up / down monthly
- No offshore, no juniors
Apps that still run. Code we still ship.
“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!
