Who this is for
Startup MVPs
Ship fast with a backend that won’t collapse later—auth, core APIs, and scalable data models from day one.
High-Traffic Systems
Caching, rate limits, queues, and scalable infrastructure for products that see spikes, growth, and heavy reads/writes.
Realtime Products
Messaging, notifications, live updates, and activity feeds with proper event design and reliability patterns.
Data-Heavy Workflows
Imports, exports, pipelines, scheduled jobs, and long-running tasks with retries, idempotency, and monitoring.
AI Add-ons
AI add-ons we can integrate
Want an “AI layer” on top of your backend? We can add RAG search, agent tools, and automation workflows as optional modules—built with proper auth, logging, and cost/latency controls.
We design AI integrations as well-bounded services (with evals and safe fallbacks) so your core APIs stay stable and maintainable.
Includes: secure API boundaries + handoff notes + monitoring baseline.
FAQ
Frequently asked questions
Timeline depends on scope. MVPs typically take 8-12 weeks, while larger projects can take 4-6 months. We provide detailed timelines during the estimate phase.
We offer both fixed-price and time-and-materials pricing. Fixed-price works best for well-defined projects, while T&M is ideal for evolving requirements.
Yes, we offer maintenance packages including bug fixes, security updates, and feature enhancements after launch.

Delivery considerations for your region
Data and risk discovery (United Kingdom)
Privacy, security, residency, and regulatory requirements differ by workflow. We document the applicable data flows, roles, retention needs, and control owners before recommending an architecture.
The resulting proposal lists the controls and evidence that are actually in scope. It is not a generic compliance, certification, or legal-assurance promise.
- Map data sources, destinations, roles, and sensitive fields
- Record access, retention, logging, and deletion requirements
- Identify required security or procurement evidence before contracting
- Use an NDA or DPA only when the parties mutually execute it
Working model (United Kingdom)
Exact live-overlap hours, response expectations, meeting windows, and escalation contacts are confirmed in the proposal for each engagement.
Written decisions, scoped milestones, and asynchronous updates reduce unnecessary meetings without implying an unagreed service level.
- Proposal-specific overlap and meeting windows
- Named owners for decisions and blockers
- Written scope, assumptions, and change decisions
- Milestone cadence agreed before kickoff
Commercial setup (United Kingdom)
The contracting entity, proposal currency, invoicing cadence, payment terms, intellectual-property terms, and required vendor documents are agreed before work begins.
The Opportunity Sprint can establish the evidence needed to scope a production pilot; it does not pre-commit either party to a rollout.
- Contracting entity and currency confirmed in writing
- Milestones and acceptance criteria defined in the proposal
- Vendor-document requirements identified before signature
- Scope changes require an explicit written decision
Delivery controls (United Kingdom)
Testing, observability, release, security, and handover controls are selected for the actual system risk rather than promised as a generic bundle.
Acceptance measures and production responsibilities are recorded before implementation so both teams know what evidence will support release.
- Risk-based testing and acceptance measures
- Release, rollback, and observability responsibilities
- Security controls tied to the agreed threat model
- Handover artifacts defined in the signed scope
