Custom software services

React, React Native, Node.js, MySQL and Next.js app creation services.

Hire a UK developer for social networking and messaging apps, cross-platform Apple App Store and Google Play projects, admin dashboards, customer portals, SaaS tools, React web applications, separately engineered Node.js APIs, MySQL systems, Next.js stores, AI-assisted payment-gateway integrations, including experience with Stripe, and SMTP integration for custom-domain email addresses, existing-app upgrades, branded newsletters and automated email systems, deployment support, and other custom software—with a tailored plan, quotation, and continued engineering support. Template-based custom Next.js stores and focused Next.js Magic UI builds start from £500.

Your contact information and project details stay private and are never sold, published, shared with other customers, or used for unrelated marketing. Reviews are always optional, may be anonymous, and choosing not to provide one is completely fine.

Project inquiry

Tell me what you want to sell or build.

Use this form for custom pricing on a social networking app, mobile app, admin dashboard, digital store, client portal, SaaS MVP, API, integration, upgrade, deployment, or another custom software project. The form securely records your inquiry and sends it directly to my business email for a response.

Private by default. Your contact and project details are used only to respond to and deliver your enquiry. They are never sold, published, shared with other customers, or used for unrelated marketing. Any testimonial or review is entirely optional, can be anonymous, and can be skipped altogether.

Preview and staged approval

Review working software before the final handoff.

I can provide secure previews throughout the agreed project so you can analyse progress, test important workflows, and request reasonable in-scope changes. The payment structure is agreed before work begins and reflects the size, risk, and engineering effort involved.

Private progress previews

I can provide a private web preview or suitable mobile test build so you can inspect agreed work before approving the next milestone or final payment.

Request included changes

You can request reasonable revisions covered by the agreed scope at no extra charge before confirming that the build is right for you.

Payment terms matched to scope

A focused lower-cost build may qualify for payment after preview. Complex custom applications require an agreed deposit or paid milestones before substantial engineering begins.

Focused websites or template-based builds may be eligible for approval and payment after a completed preview. Substantial React, React Native, Node.js, API, authentication, or MySQL projects require a deposit, paid discovery, or milestone payments because they consume significant engineering time, testing effort, infrastructure, and paid AI-development resources such as ChatGPT Codex usage. A complex completed application therefore cannot be declined without paying for work already approved and completed. New features outside the agreed scope are quoted separately. Source code, production credentials, final deployment, and third-party licences are transferred only after the final balance is paid.

Software terms explained

MVP and SaaS in plain English

These terms describe the type and stage of an application, not a fixed technology or package.

MVP

Minimum Viable Product

The first genuinely usable version of an application. It concentrates on the essential features needed to solve the main problem and test the idea with real users before more time and budget are invested in every planned feature.

SaaS

Software as a Service

Software that is hosted online and used through a browser or app. Customers normally sign in to an account, and the provider operates the application, database, updates, and infrastructure. Some SaaS products charge a recurring subscription, but not all do.

SaaS MVP

A focused first version of an online service

An initial SaaS release containing the core customer journey, accounts, data, and operational tools needed to validate the service. MVP describes a deliberate limit on feature scope—not low engineering quality, weak security, or an unfinished interface.

Honest performance guidance

Choose visual effects that suit your customers' devices.

Next.js itself can be fast, but animation-heavy Magic UI components, large templates, WebGL effects, blur layers, and excessive client-side JavaScript may feel slow or less smooth on older phones and computers. I will explain this trade-off before recommending a design.

Faster alternatives when animation is not essential

  • Lean React interfaces with purpose-built components and fewer dependencies
  • Restrained business interfaces with predictable controls instead of constant motion
  • Standard HTML and CSS sites for simple content, speed, and broad compatibility
  • Reduced-motion versions of animated layouts for older or lower-powered devices
  • Performance testing before launch so design choices match the target audience

A lighter custom React build or standard HTML/CSS website is often a better option when maximum smoothness, accessibility, and support for older hardware are more important than complex animation.

A directly engineered React interface backed by a custom Node.js API and MySQL database may look more restrained than an animation-led template, but that can feel more professional for dashboards, portals, stores, and operational applications. Fewer decorative effects and third-party visual layers can mean more predictable controls, clearer feedback, easier maintenance, and fewer distracting hover, scrolling, stacking, or low-powered-device glitches. Performance still depends on careful architecture, implementation, and testing rather than the technology names alone.

Custom admin dashboards

Useful admin dashboards and internal tools for real work.

I can design and build private admin areas for ecommerce stores, social platforms, SaaS products, React Native mobile-app backends, customer portals, and other data-driven applications. Each dashboard can be tailored to the project's database, APIs, staff roles, and everyday workflows.

  • Projects, revenue, downloads, enquiries, and audience insights
  • Useful operational tools connected to your real application data
  • Custom Gmail-style inboxes with received messages, attachments, replies, search, workflow statuses, routing details, and useful email metadata
  • Private authentication, operational logs, and file sharing
  • AI-selected recent news tailored to the business, industry, risks, competitors, or technology stack

Secure project delivery

Working with me includes practical tools for sharing large files.

Instead of passing large builds, videos, project folders, and design assets through ordinary email attachments, I can create a protected CodeKits transfer link. Clients can download files from me, upload files back to the private admin workspace, or use both directions through one clear portal.

The current managed workflow supports guest files up to 10 GB and administrator files up to 50 GB, subject to available hosting capacity. Transfers use authenticated chunked HTTPS requests and restricted private server storage.

Two-way transfers

I can send large project files to you, and you can upload files securely back to the same protected workspace.

Private permissions

Each unlisted link can allow uploads, downloads, or both, while files remain outside the public website.

Automatic expiry

Choose a time limit so temporary project files are removed after the agreed sharing period.

Download-count deletion

A transfer can also close and remove its files after 1, 5, 10, 25, or 100 downloads.

Ubuntu server deployment

Cost-effective application hosting on an Ubuntu VPS.

I am experienced in selecting, configuring, and securing virtual private servers without making customers pay for capacity they do not need. As a working example, one £6-per-month Ubuntu VPS from a UK provider can run this Next.js and Magic UI website, the Encrypted Messenger iOS app's Node.js backend, and the local MySQL database together. I match the server to the project, prepare a tailored deployment command sheet, and explain the setup in plain English. Hosting requirements and provider charges vary with traffic, storage, backups, email, performance, and availability needs, so growing or business-critical systems may require more capacity.

  • Cost-conscious VPS comparison, selection, and right-sizing
  • One-server deployment for this Next.js site, mobile API, and local MySQL
  • Ubuntu package and security update commands
  • Node.js backends, MySQL databases, Next.js, and production builds
  • PM2 process management and automatic restart setup
  • Nginx reverse proxy, domain, SSL, and validation guidance
