Serge BelovCustom Software Development
From idea to production-ready software, built to your exact specifications.
What this is
Off-the-shelf software almost fits. Custom software fits exactly. I design and build web applications, internal tools, APIs, and digital products tailored to how your business actually works — not how a SaaS vendor thinks it should.
Who it's for
- Startups that need an MVP built fast and done right
- Businesses with workflows that no existing tool handles well
- Teams replacing brittle spreadsheets or legacy internal tools
- Founders who need a technical co-builder, not just a coder
Problems it solves
- Your team works around your software instead of with it
- You're duct-taping three different SaaS tools together
- Off-the-shelf options are either too simple or overkill expensive
- You've been burned by freelancers who delivered something unmaintainable
What you get
- Production-deployed web application or API
- Clean, documented source code (you own it fully)
- Technical documentation and architecture notes
- Handoff session with your team
- Two weeks of post-launch support
How it works
- 1
Discovery
We map out requirements, constraints, and success criteria in a structured session. No assumptions.
- 2
Specification
I document the architecture, data model, and feature list before writing a line of code. You approve it.
- 3
Build
Iterative development with regular check-ins. You see progress weekly, not at the end.
- 4
Review
Structured testing and feedback round. Edge cases addressed, UX refined.
- 5
Deploy
Launch to production with monitoring in place. I stay on standby for two weeks post-launch.

Team training session
Two-hour walkthrough of the codebase and deployment process for your internal team.
Frequently asked questions
What's the minimum project size?
Projects start at $2,500. This typically covers a focused MVP or a well-scoped internal tool. Larger projects are scoped individually.
What tech stack do you use?
Primarily TypeScript, React/Next.js, Node.js, and PostgreSQL — but I choose the right tool for each project. If you have an existing stack, I work within it.
Who owns the code?
You do. Full source code transfer at project completion. No licensing gotchas.
How long does a typical project take?
A focused MVP takes 4–8 weeks. Larger applications take 2–4 months. Timeline is agreed upfront during scoping.
Do you do hourly work?
For custom development I work on fixed-scope projects, not hourly. This protects you from scope creep and gives you predictable costs.
