From the first design decision to a running system — Kaarastu handles architecture, development, and ongoing engineering so you don't have to build an internal team first.
Platforms built for 500K+ daily active users. Event-driven systems processing 1M+ events/day.
Building a platform usually means managing three separate relationships: someone to design it, someone to build it, and someone to maintain it. Each handoff loses context. The agency that designed it is gone by the time the first production incident happens. The developer who built it didn't write the documentation. The person maintaining it inherited a system they didn't build.
Most platform problems are slow delivery, mounting technical debt, systems that break under growth. All of these trace back to decisions made early that nobody owns anymore.
This engagement fits when:
Warning signs
A product to build but no engineering team to build it
Platform working today but not designed for where the business is going
Technical debt accumulating with no one owning it
Dependent on a single developer or vendor with no continuity plan
We map what your system needs to do today and what it needs to handle as the business scales. Service structure, data design, integrations, and technology selection is documented before a line of code is written.
Kaarastu builds the platform from the design: the core system, data layer, third-party connections, and deployment setup including AI and computer vision solutions as needed.
After launch, Kaarastu engineers remain available for incidents, product changes, and service ownership. Scope and availability are defined in the retainer agreement.
When you're ready to hire internally or transition ownership, Kaarastu prepares for it: documentation, knowledge transfer, and a structured handover plan.
Questions we answer
I have a product idea. Who designs and builds the system behind it?
My platform is breaking under growth. Who owns fixing it?
I need engineers but I'm not ready to hire a full team yet.
What happens to the platform if I want to bring it in-house later?
We need AI or computer vision capabilities built into our platform. Can you handle that?
Both. Some clients need a blueprint their team will implement. Others want us to build the core platform services, data layer, and deployment pipeline. We can also do a phased approach: blueprint first, then decide together whether Kaarastu or your team handles execution.
Blueprint phase: 4–6 weeks. If we're building the platform, add 3–6 months depending on scope. A focused MVP platform differs from a full multi-service foundation. We break execution into milestones with demos every two weeks, so you're not waiting months for visibility.
Documentation, working sessions, and a transition period. You receive architecture documentation, deployment runbooks, and operational guides. We run working sessions with your team to transfer context. For the first few weeks post-handoff, we remain available for questions and review. We ensure your team can work independently.
Yes. We've built AI and computer vision systems as part of platform engagements. The same engineering discipline applies: defined interfaces, observability, and systems your team can operate and extend after we hand off.
MySQL, PostgreSQL, or DynamoDB for data; Kafka or SQS for messaging; Kubernetes or ECS for orchestration. What we recommend depends on your team's expertise, existing infrastructure, scale requirements, and budget.
A senior architect will review your situation and recommend the right starting point.
