Built for your next step

Prepare your product for the next stage of growth.

Performance problems rarely come from a single source.

Slow database queries, inefficient APIs, poorly designed background jobs, external services, infrastructure limits, caching strategy, application architecture, and frontend behaviour can all affect customer experience.

We investigate the real bottlenecks and engineer improvements based on evidence.

Best suited for

  • Growing SaaS businesses
  • marketplaces
  • e-commerce platforms
  • FinTech products
  • AI platforms
  • products experiencing slow response times
  • applications expecting significant traffic growth

What success looks like

Measure agreed performance baselines, identify bottlenecks and compare selected improvements using before/after measurements where technically appropriate.

Inside the engagement

Typical warning signs

  • Pages become slower as usage increases
  • APIs have unpredictable response times
  • Database load is increasing rapidly
  • Cloud costs rise faster than customer growth
  • Background jobs fall behind
  • Peak traffic causes failures
  • External API calls slow down core workflows
  • Users experience intermittent timeouts
  • Engineering teams are unsure where the bottleneck actually is

Inside the engagement

What we analyse

Application performance

We investigate important application workflows and backend execution.

Database

We examine relevant query behaviour, indexing, data access, and connection patterns.

API performance

We investigate latency across internal and external service calls.

Infrastructure

We review relevant compute, memory, networking, containers, serverless services, or other resources.

Caching

We determine where caching could meaningfully improve performance.

Background processing

We review queues, jobs, workers, and asynchronous workloads.

Concurrency

We identify potential limitations around simultaneous usage.

External dependencies

We identify third-party services contributing to latency or instability.

Observability

Where appropriate, we improve metrics and instrumentation so bottlenecks can be measured rather than guessed.

Inside the engagement

Scaling engineering may include

  • query optimisation
  • caching implementation
  • application refactoring
  • queue architecture
  • horizontal scaling
  • load distribution
  • asynchronous processing
  • database optimisation
  • infrastructure changes
  • API optimisation
  • CDN improvements
  • monitoring enhancements

Inside the engagement

Our principle

Measure first. Scale second.

We do not recommend expensive infrastructure changes merely because growth is expected.

The objective is to understand where actual bottlenecks exist and make proportionate engineering decisions.

Production load testing requiring specialised infrastructure or significant third-party consumption may be scoped separately.

From first conversation to handover

A clear path to delivery

  1. 01

    Technical Discovery

    We understand your product, current technology stack, business priorities, known problems, and desired outcome.

  2. 02

    Agree the scope

    Define the systems, repositories, access, review areas or implementation work, deliverables and acceptance criteria for your engagement.

  3. 03

    Review & engineer

    Assess the agreed product areas, document evidence and carry out any engineering improvements included in scope, with regular progress reviews.

  4. 04

    Prioritise & hand over

    Walk through findings and completed work, confirm next priorities and hand over the agreed documentation and recommendations.

The details that matter

Before we get started

A few things to know about scope, timing and working together.

Is this a fixed-price package?

The displayed prices are indicative. We agree a defined scope, acceptance criteria and a project quote before work starts. Requests beyond that scope are estimated separately.

What do you need from our team?

A product or operations contact, access to the agreed systems and documentation, representative test data, and timely feedback. We confirm access and integration dependencies before scheduling delivery.

When does the delivery timeline begin?

The target delivery window is 3–6 weeks, starting once scope, access and dependencies are ready. Third-party approvals or changes to the agreed scope can affect timing.

What happens after delivery?

We hand over the agreed deliverables and documentation with a walkthrough for your team. Further features, monitoring and ongoing maintenance can be scoped as a separate engagement.

Prices are indicative GBP project ranges. Final scope, deliverables, acceptance criteria and price are agreed before work starts. Timelines assume defined scope, available technical access and compatible third-party integrations. Vendor, infrastructure, regulatory and licensing costs are excluded.
