Custom software development
for your stack, scale, and timeline.
Backend services, data platforms, integrations, internal tooling, and embedded AI. We build for the shape of your business, not a vendor template. The code is meant to last a decade, not a demo.
Software that fits your business, not the reverse.
Every business has rules, workflows, and edge cases that no off-the-shelf product covers cleanly. Custom software development turns those rules into production systems. Backend services, data pipelines, integrations, admin tooling. The code encodes how you actually work.
We've done this for eighteen years across finance, healthcare, retail, logistics, energy, and the public sector. Languages and frameworks change. The discipline holds. Clear domain modelling, honest delivery plans, and code that a new team can still read three years from now.
Shipped under this discipline.

APIs, data, integrations and the legacy you need to retire.
Most engagements mix two or three of these. We scope the exact cut during discovery and write it into the statement of work.
Backend APIs and services.
The core everything else depends on, built so it holds up as you grow. REST, GraphQL, or gRPC services carrying your business logic, with clean domain models, versioned APIs, observability that means something, and SLAs you can hold us to.
Data platforms and pipelines.
Turn scattered data into answers your team can trust. ETL and ELT pipelines, warehousing, streaming, and analytics APIs on Snowflake, BigQuery, or Postgres, with data contracts and lineage that survive audits.
Systems integration.
Stop your tools fighting each other. We wire your CRM, ERP, billing, identity, and bespoke systems into one coherent fabric, event-driven where it helps and batch where it makes sense, never both by accident.
Internal tools and admin.
Give the team software that does the job instead of a spreadsheet. Ops consoles, approval workflows, reporting dashboards, and configuration UIs, built so your people stop exporting CSVs from three places.
AI and ML features.
AI that earns its place in the product, not a demo that impresses once. Embedded ML for search, recommendations, classification, document parsing, and LLM-powered assistants, evaluated against real data, shipped behind feature flags, and priced per query.
Legacy modernisation.
Replace the system that's slowing you down without stopping the business. Strangler-fig migrations, monolith decomposition, framework upgrades, and database swaps, released incrementally so the old system retires quietly while you keep shipping.

We pick the stack to fit the problem, not the other way round. These are the tools our engineers ship with most often. We'll adopt whatever fits an existing estate.
Pick the engagement model
that fits the commitment.
The same custom software development work ships under any of these three commercial shapes. The difference is in how you hold us accountable and how you scale up or down.
Custom software with AI built in.
Most custom systems now have a job a model can do well: reading documents, drafting replies, routing work. We add it where it pays, with the same tests and audit trail as the rest of the code.
Explore AI developmentWhat it costs.
We price in the offshore band: a blended team rate in the mid-$30s to mid-$50s per hour, per person ($35–55). At a full-time 160-hour month that is roughly $5,600 to $8,800 per team member. For comparison, blended onshore UK and US rates typically run $150–210 per hour, and nearshore $55–90.
These are indicative ranges, not a quote. Seniority mix, team size and engagement length move the number; we confirm a monthly figure after a discovery call. Read the full cost guide.
| Model | Per hour | Per month (160h) |
|---|---|---|
| Cloudini (offshore) | $35–55 | $5,600–$8,800 |
| Nearshore | $55–90 | $8,800–$14,400 |
| Onshore UK / US | $150–210 | $24,000–$33,600 |

Custom software development is bespoke engineering of backend services, data pipelines, integrations, admin tools, and embedded features. We build to your exact requirements, not by configuring a packaged SaaS product. We start from your domain model and deliver a system that encodes your business rules in code you own.
You own every line of code, every artefact, and all the IP from the first commit onwards. Our contract includes explicit IP transfer. You keep the repositories, documentation, and runtime access regardless of engagement status.
Stack choice follows the problem, the existing estate, and the team you'll operate it with. There's no vendor relationship on our side. If you're already on Java and AWS, we don't propose rewriting it in Go on GCP. If the problem warrants a new stack, we document the trade-offs before any code is written.
A typical engagement runs two to eight weeks of discovery (architecture, domain model, delivery plan), followed by two-week sprints with Friday demos and production deploys from week three or four. Most custom-software engagements run six to eighteen months. Longer ones continue as an ongoing partnership.
Yes. Most of our engagements add to an existing codebase rather than starting from scratch. We onboard to your conventions, linting rules, and review process in week one. Our engineers attend your architecture reviews and retrospectives from day one.
Every engagement has written quality gates in the statement of work. Unit-test coverage targets, static analysis rules, code-review SLAs, and release-quality thresholds. We also run end-to-end tests where the risk justifies them. If a quality gate slips, we fix it before the next release rather than after.
Custom software development is the discipline, the thing that gets built. Dedicated teams, offshore development centres, and staff augmentation are the commercial models for how you engage us to do it. You can get custom software work under any of the three engagement shapes.
We are a mental health charity and not tech-minded. We needed to improve our patient registration system but wanted a company that we can relate to. Hassan took the time to meet with me and patiently went through our process to find a personalised solution for us. Hassan's team did a great job streamlining our process and connected our registration system to our patient management software. Whenever we have a glitch, they resolve this quickly.
Let's build from here.
