Custom software development
Bespoke applications modelled on your domain rather than a template: typed backends, considered data models, automated tests and a deployment path that exists from the first week.
Service index
Each service below is delivered by engineers who take part in the design, the implementation and the operation of what they build. Scope, constraints and expected outcomes are agreed in writing before delivery starts.

Bespoke applications modelled on your domain rather than a template: typed backends, considered data models, automated tests and a deployment path that exists from the first week.
Responsive, accessible web applications with server rendering where it helps, measured performance budgets and interfaces built on a documented design system.
Architecture and implementation on managed cloud services: environment design, networking, storage strategy, scaling behaviour and cost-aware resource sizing.
Service boundaries, data ownership, integration patterns and failure modes, documented as decision records that your team can extend after we finish.
Versioned APIs and dependable connections between systems: contract-first design, idempotent processing, retries, backpressure and clear error semantics.
Batch and streaming pipelines, warehouse and analytical modelling, migrations, quality checks and lineage so reported numbers can be traced to their source.
Infrastructure as code, reproducible environments, container orchestration, build and release automation, plus rollback paths rehearsed before they are needed.
Threat modelling, access and secret management review, dependency and configuration assessment, and practical remediation ordered by risk rather than convenience.
Test strategy and automation across unit, integration, contract and end-to-end levels, with load testing and regression coverage tied into the pipeline.
Focused review of an architecture, a delivery process or a technology choice, concluding in written findings, options and trade-offs you can act on independently.
Incremental modernisation of software already in production: mapping current behaviour, isolating risky areas and replacing them in steps that keep the system running.
Maintenance of live systems: monitoring and alerting, dependency and platform updates, incident response, performance tuning and continuing small improvements.

A scoped outcome delivered by a Horizon Bop team that owns design, build and release.
Our engineers work inside your team, following your standards, rituals and review process.
A time-boxed assessment producing written findings, options and a prioritised plan.
