Software engineering services for business systems, platforms and AI

How our services fit together

Three capabilities, one engineering team

Bit & Byte Lab is a software engineering company. Most of our work falls into three areas: custom software and SaaS, web platforms, and AI and automation. Mobile apps, UI/UX design, cloud operations and ongoing maintenance support all three.

We also build and run our own products. Sublime Care Cloud, Faatura Cloud and Sublime Groceria are in production, so we design client systems for what happens after launch, not just for launch day.

We take on new builds and existing systems. Fixing, modernising and connecting software that someone else started is a large part of what we do.

What working with us looks like

  • One team from discovery to long-term support
  • Software shaped around your process
  • .NET, Angular, Flutter, Laravel and PHP
  • Hosting and maintenance after launch
  • UK-registered company, No. 16104230

Primary capabilities

Web platforms

Applied AI

The engineering around every system we build: apps, interfaces, infrastructure and long-term upkeep.

Mobile app development

UI/UX design

Interfaces for SaaS products, ERP dashboards, portals and data-heavy screens, designed so people can actually use them.

Questions about our services

What people usually ask before starting a project with us.

What does Bit & Byte Lab build?

Custom business systems and SaaS, web platforms, and AI and automation. Mobile apps, UI/UX design, cloud operations and ongoing maintenance support that work. SEO, content and social media are secondary services we offer to clients whose platforms we build.

Can you take over or fix an existing system?

Yes. We take over, fix and modernise software built elsewhere. For Elliott Wave Forecast we replaced a legacy membership system with a custom Laravel platform connected to the client’s existing WordPress site.

How much does a software or web project cost?

It depends on scope: the number of users, features and integrations, and how complex the business rules are. After a short discovery conversation we give you an estimate and a phased plan, so you can start with the part that delivers value first.

Do you work with businesses outside the UK?

Yes. Bit & Byte Lab Ltd is a UK-registered company (No. 16104230) with a registered address in London and its engineering team in Gujranwala, Pakistan. We work with clients remotely.

Which technologies do you use?

Our main stack is .NET 8 and ASP.NET Core with SQL Server, Angular for web interfaces and Flutter for mobile apps. We also build with PHP, Laravel, WordPress, WooCommerce and Magento, run Linux servers, and deploy self-hosted AI models where data needs to stay in-house.

Do you support software after it launches?

Yes. We host, maintain and keep improving what we build, from security updates and fixes to new features. Our own products are maintained the same way, so long-term support is part of how we work.

Not sure where to start?

Tell us what you need built, fixed or improved. We’ll recommend the right place to start.
