One scope, one price, one timeline.
For work that can be clearly defined. Everything is agreed in writing before we begin, and any change is quoted separately so the number never drifts quietly.
Best forMVPs, defined features, rebuilds
SParkk Nexus designs and engineers custom software on contract. Web platforms, mobile apps, internal systems, integrations and AI, taken on in any shape, for clients who value doing it properly.
We are generalists by intent. One team that can take a product from an idea on paper to a system in production, whatever it needs to run on.
Customer-facing products, portals and dashboards, built to carry real traffic and stay maintainable.
Native and cross-platform apps for iOS and Android, from the first release through to scale.
ERPs, CRMs and the bespoke internal tools that quietly run an operation behind the scenes.
Practical machine learning, LLM features, data pipelines and analytics that earn their place.
Architecture, migration and DevOps on AWS, Azure, Google Cloud and Cloudflare.
APIs, payments, third-party platforms and the dependable glue that connects them.

No two projects are priced the same, because no two projects are the same. We quote on the work itself, and we will tell you early if we are not the right fit for your budget.

Every engagement includes
You always know what is being built, what it costs and when it lands. The same five stages, scaled to the size of the job.
We learn the business before the brief: requirements, constraints and what success actually looks like.
1 to 2 weeks
Architecture, data models and interface design, reviewed and signed off before any build begins.
2 to 4 weeks
Short cycles, working software every fortnight, and a staging environment you can use throughout.
Fortnightly releases
Security review, load testing and a calm, rehearsed go-live with a rollback plan in hand.
Planned to the day
Warranty, maintenance and ongoing development, for as long as the product needs us.
Ongoing
We would rather do fewer projects exceptionally well than many adequately. It is the reason clients come back, and the reason we can afford to be honest with them.
We take on a limited number of engagements at a time, so every client gets senior attention rather than whoever happens to be free.
Quotes are itemised and explained line by line. If the budget and the brief do not match, you will hear it from us first.
Source code, designs, documentation and infrastructure accounts belong to you from the first commit. No lock-in, ever.
Much of our work happens under NDA. We never name a client or show their work without written permission.
A short email is enough to start. We reply within two working days, either with questions or a time to talk. Everything you send is treated as confidential.
