We design and deliver high-performance websites and web applications for businesses — engineered with modern stacks, clear scope, and the same rigour behind the ToolBoxesAI product suite.
What we deliver
End-to-end websites and tools — scoped clearly, engineered for production, and built for real-world use.
Interface layer
Responsive, conversion-focused interfaces with modern HTML, CSS, and JavaScript — with or without frameworks like React and Vue.
Systems layer
Robust APIs, databases, and server logic across Node.js, Python, Go, and other proven stacks — secure, scalable, and maintainable.
Product delivery
Complete web applications from architecture through launch — one accountable engineering team across frontend, backend, data, and deployment.
Experience design
Intuitive flows, premium visual systems, and interfaces that feel deliberate — aligned to your brand and your users' goals.
Our work

Who we are
DevFreelance is the custom web development arm of ToolBoxesAI — the team behind 50+ browser-based productivity tools used worldwide. We bring that same engineering discipline to client websites and web applications: scoped clearly, built in the languages each project requires, and delivered with production standards from day one.
Our work spans interfaces, APIs, data layers, and deployment pipelines. We combine solid architecture with thoughtful design so every release is maintainable, secure, and straightforward for your users — not just impressive in a demo.
How we work
Structured delivery from discovery through launch — defined scope, steady communication, and production-ready output.
Initiation
Objectives, audience, technical constraints, and delivery boundaries are captured and agreed before build work begins.
Blueprint
System structure, data models, API contracts, and interface direction are defined to match the approved scope.
Engineering
We build across the stack in the programming languages and frameworks each project calls for — web interfaces, APIs, data layers, and integrations — selected for the scope, not limited to a single stack.
Verification
Responsive behaviour, browser coverage, API reliability, performance, and security are verified against the agreed acceptance criteria — including checks for common vulnerabilities so releases are harder for malicious attackers to exploit.
Release
Containerised release via Docker, environment configuration, and a controlled rollout to production infrastructure.
Continuity
Documentation, agreed maintenance, and measured follow-up after launch — scoped to what the project requires.
Client feedback
Notes from teams we have shipped for — scope, communication, and delivery.
Before you reach out
Clear answers on scope, timelines, pricing, and how we work — so you know what to expect before starting a project.
Timelines depend on scope and complexity. A focused marketing site may take a few days; a full web application typically spans one to several weeks. During the initial scoping call we outline milestones, review points, and a realistic delivery schedule before any build work begins.
We offer fixed-price engagements for well-defined scope and flexible arrangements for ongoing work or evolving products. After reviewing your requirements, we provide a clear quote with deliverables, milestones, and no hidden fees. Larger projects may include phased payments tied to agreed checkpoints.
Yes. We offer post-launch maintenance and support packages so your site or application stays updated, secure, and performing well. Support can cover security patches, dependency updates, content changes, monitoring, and measured follow-up — scoped to what your project actually needs.
We build across the stack in the languages each project calls for — not a single prescribed stack. That includes JavaScript, TypeScript, Python, Go, Rust, Java, C/C++, and more on the backend; React, Vite, Vue, and modern HTML/CSS on the frontend; plus PostgreSQL, SQLite, MongoDB, Docker, and CI/CD for delivery. The right tools are chosen for your scope, timeline, and maintainability.
We follow a structured path: discovery and scoping, architecture and planning, build and integration, review and QA (including security checks), deployment, then handover and optional support. You receive steady progress updates and defined review points so there are no surprises at launch.
Yes. We regularly take on redesigns, refactors, feature additions, and performance improvements on existing projects. We start with a technical review to understand the current architecture, risks, and the most practical path forward — whether that is incremental improvement or a controlled rebuild.
Upon full payment, you own the final delivered product. We retain the right to showcase completed work in our portfolio and to reuse generic techniques and patterns developed during the project. Third-party assets such as fonts, libraries, or stock media remain subject to their own licences.
Share your goals, timeline, and any reference materials through our contact form. We will respond with clarifying questions, a recommended approach, and a scoped proposal. Once scope and terms are agreed, we schedule kickoff and begin the discovery phase.
Tell us what you need — we will map the requirements, recommend the right stack, and deliver a website or web application your team can rely on.
