Base Brain Build

Architecture-first engineering studio

Scalable systems, designed and built to last.

We design and build the backends, data flows and cloud infrastructure behind your product, so it stays reliable and fast as traffic and data grow. An experienced system architect leads every project.

A system designed to scale out Users on web and mobile, and partner systems, reach your platform through a gateway that balances load across any number of stateless service instances. The services read from a cache, write to a primary database that copies data to read replicas, and send events to a queue that a pool of workers consumes. Metrics, logs and traces cover the whole platform.

Built to scale out: add instances as traffic grows.

One team of backend, frontend and mobile engineers, remote-first, working with clients worldwide across time zones. Fixed price or time and materials, whichever fits the work. You own the code: we work in your repositories and cloud accounts, or build in ours and hand everything over.

Services: the systems your product runs on

Most of our work sits below the interface, in how data moves, how services talk to each other and how the system behaves under load.

All services, in detail

  • Scalable system design

    We design the service boundaries, data models and failure handling of new systems, and review existing ones before growth exposes their limits.

    More about system design

    Typical work

    • Architecture for a new product or platform
    • Reviews of systems starting to strain
    • Migration plans for legacy systems

  • Distributed, high-load backends

    We build the services, APIs and workers that carry your traffic, with queues, caching and data stores chosen for the load you expect.

    More about backend development

    Typical work

    • APIs and services for high-traffic products
    • Background processing with message queues
    • Real-time processing of live data

  • Performance engineering

    We find where the time goes, in queries, services or infrastructure, and fix the slow parts, measuring before and after each change.

    More about performance engineering

    Typical work

    • Database and query tuning
    • Profiling slow services and endpoints
    • Load tests and capacity planning

  • Data flows and integrations

    We connect your system to partner APIs and third-party feeds, and keep data consistent as it moves between services, live or in batches.

    More about data integrations

    Typical work

    • Normalizing feeds from several providers into one model
    • Webhooks that send only what changed
    • Two-way sync with third-party platforms

  • Cloud infrastructure and reliability

    We set up the cloud environments, containers and deployment pipelines your system runs on, with monitoring, alerting and recovery plans built in.

    More about cloud infrastructure

    Typical work

    • Cloud environments defined as code
    • Deployment pipelines and container orchestration
    • Backups, failover and recovery testing

What we build on top

The same team builds the apps and features that run on the systems we design.

  • Web appsBack offices, dashboards and customer-facing web apps, built on APIs we design.
  • Mobile appsCross-platform mobile apps that share a backend with your web product.
  • AI featuresLLM-based search, summaries and assistants, connected to your data, with cost and quality monitoring.

A good place to start

Architecture Review

For teams expecting more load, fighting slowdowns or deciding whether to rebuild.

A few weeks, with the scope fixed before we start.

Ask about a review How the review works

What you get

  • A map of your current architecture and data flows
  • Bottlenecks and failure risks, ranked by impact and effort
  • A target design and a step-by-step plan to reach it
  • A written report and walkthrough, yours to act on with or without us

Products and systems we have delivered

Three of the seven systems on our work page: our own product, a trading platform and a data platform.

  • Receipt OCR service

    Scope
    API, infrastructure, operations
    Our role
    Built and run by us
    Services
    Backend development, Performance engineering, Cloud infrastructure

    A paid API that reads photos of receipts and returns structured data: the total, the receipt number and the other fields a client needs. Every result carries a confidence score, and low-confidence reads are retried on a stronger model before the client sees them. The service spreads its load across several regions, caches repeated prompt content and tunes image resolution to keep the cost per receipt low. We run it in production, so monitoring, model upgrades and cost control are on us.

  • Trading back office for a sportsbook

    Scope
    Backend, frontend, integrations
    Our role
    Architecture and delivery
    Services
    System design, Data integrations

    We designed and built the system around one canonical model of sports, competitions, matches and markets, with fixtures and odds from several providers. Traders create each match once, choose which source supplies each market, and reuse market settings such as minimum and maximum stakes across a whole competition or league. The design covers pre-match and in-play (live) markets from the first release.

  • End-to-end real estate platform

    Scope
    Data platform, backend, web and mobile
    Our role
    Architecture and delivery
    Services
    System design, Performance engineering, Data integrations

    A platform that takes listing data from several multiple listing services, brings it into one standard model and serves it to search, matching and agent tools on web and mobile. Each feed arrives in its own format and on its own schedule; the ingestion layer reconciles them, records every change and keeps the search index fresh. The data model follows the real estate industry standard (RESO), so new feeds and partner integrations plug in without rework.

We leave out client names for confidentiality. All seven projects.

How we work: fixed price or time and materials

Whichever you choose, the design work, code quality and communication stay the same.

  • Fixed scope

    Fixed-price project

    Best for well-defined work with a set budget and deadline

    We fix scope, milestones and price before work starts. If something changes, we price the change and get your written approval first.

    • One price for an agreed scope
    • Milestones with working demos
    • Acceptance criteria agreed up front

  • Flexible scope

    Time & materials

    Best for ongoing development, or products still taking shape

    The team works from your priorities, and you pay for the time spent at agreed rates. You can change direction without renegotiating the contract.

    • Priorities you can change as you learn
    • Roles you can add or remove as the work changes
    • Time reported against tasks

In every project

  • Direct contact with the engineers
  • Architecture decisions in writing
  • Code review on every change
  • Regular demos and progress updates
