We build the systems other software can't
Yenidan designs, builds, and operates custom platforms and applied-AI systems for organizations whose work doesn't fit an off-the-shelf product.
How an AI workload moves
Engineers first,
vendors never
We were building and running our own products long before we took on client work. That's the experience behind every engagement.
Yenidan started as a way to stop rebuilding the same foundations for every new idea. We shipped our own platforms across healthcare, commerce, and education first — which means we've paid for our own bad estimates, carried our own pagers, and rewritten our own shortcuts. We bring that scar tissue to your project.
Right-sized architecture
Native where it matters, shared where it doesn't. We don't build for a team ten times our size.
We build it, not just spec it
Design, engineering, and QA sit in one team — not three vendors passing a document between them.
We own the outcome
We stay on after launch. Software is maintained, not handed over.
Small by design
Fewer handoffs, faster decisions, and nowhere for a bad idea to hide.
Selected
engagements
Client names and implementation details stay private. Interfaces shown are representative compositions, not client screens.
Clinical reporting
Helped a clinical care provider modernise how they capture and report patient records — replacing manual re-entry with a structured, reviewable workflow.
Field operations
Helped a field services company bring scheduling, job tracking, and invoicing into a single system that works the same on a laptop and on a phone in a van.
Marketplace platform
Helped a marketplace operator bring buyers, sellers, and inventory onto one platform — with the listing, checkout, and settlement flows that hold a two-sided market together.
Assessment engine
Helped an assessment provider build a more reliable, research-backed scoring system.
Programme management
Helped an education provider simplify enrolment, attendance, and payments.
Native mobile apps
Helped a community platform launch native iOS and Android applications.
What we
deliver
Four technical disciplines and six ways to engage — most projects combine at least two of each.
Core disciplines
Web platforms & SaaS
Multi-tenant applications built for real operations — dashboards, billing, scheduling, and the workflows underneath.
Next.js · Node · Postgres · PrismaNative & cross-platform mobile
iOS and Android written natively in Swift and Kotlin, or shared via React Native when speed outweighs platform polish.
SwiftUI · Kotlin · Expo · React NativeAI & automation
Speech, language, and scoring models wired into real workflows — never a chatbot bolted onto a homepage.
Python · FastAPI · LLM integrationMarketplaces & commerce
Two-sided marketplaces and storefronts, plus the inventory, messaging, and logistics that hold them together.
Next.js · Postgres · Stripe · ExpoWays to engage
Discovery & technical advisory
Scoping workshops and feasibility studies before you commit, so the estimate is grounded rather than guessed.
Staff augmentation
Engineers embedded in your existing team, working your stack and your sprint cadence.
Legacy modernisation
Replacing or rebuilding ageing platforms without stopping the business that depends on them.
Support & SLA
Post-launch maintenance, incident response, and uptime commitments — not a one-time handover.
Data & integrations
Payments, third-party APIs, and the pipelines that connect a new system to everything around it.
Cloud & DevOps
Deployment pipelines, hosting architecture, and the on-call rotation that keeps it standing.
How an
engagement runs
Work moves continuously rather than in big-bang handovers. Below is the shape of that flow, and the four phases behind it.
Discover
Map the real workflow, the constraints, and the people who have to live with this system every day. Ends with a scoped plan you can budget against.
Design
Wireframes and a clickable prototype before a line of production code, so the expensive changes happen while they're still cheap.
Build
Typed, tested, and deployed continuously. You see working software every week, not a demo at the end of the quarter.
Operate
Monitoring, incident response, and the next iteration. We stay on the pager after launch.
