Software development service
Freelance software developer for custom products, web apps, and internal tools
I help founders, startups, and small teams plan, build, and improve custom software. That includes MVP development, web application development, internal tool development, and stabilising existing systems when the codebase has become brittle, slow to change, or difficult to trust.
I adapt quickly across stacks, with strongest current day-to-day delivery in TypeScript, React, Next.js, Astro, and Node-based systems.
Build scope
What I build
- Custom web applications, dashboards, and client-facing products
- Internal tools, portals, and workflow software for day-to-day operations
- MVP development and feature delivery with maintainable architecture
- Refactoring, stabilisation, and technical direction for existing systems
Engagement timing
When teams usually bring me in
1. New product or MVP
You need a freelance software developer to shape and ship a serious first version, not just produce mockups or isolated code snippets.
2. Internal tools and workflows
Your team is losing time to manual work, brittle spreadsheets, or disconnected systems that should be replaced by custom software.
3. Existing codebase needs calm
The product already exists, but it needs clearer architecture, steadier delivery, and someone who can improve it without making it harder to maintain.
Project flow
How custom software projects usually work
1. Scope and priorities
We identify the business goal, the real constraint, and which version of the product or internal tool is actually worth building first.
2. Build and iterate
I implement the work directly, keeping the system understandable while shipping at a pace that suits the product and the team.
3. Hand-off and next steps
The result should be easy to operate, extend, and maintain whether I stay involved for the next phase or hand it over cleanly.
Case studies
Relevant custom software development work
These examples show the kind of product, platform, and maintainability work I take on: custom systems with real constraints, long-term structure, and clear ownership.
Semantic Knowledge Platform and Identity Infrastructure
Custom platform architecture spanning structured data, backend services, automation, deployment, and long-term system evolution.
timmit.dev portfolio
End-to-end product build covering Astro, reusable page systems, content architecture, SEO implementation, deployment, and ongoing iteration.
