00 / OVERVIEW
Why this service exists
I do custom software development for teams that need software shaped around how they actually work: not a generic SaaS subscription, not a spreadsheet with extra steps, not an agency that disappears after the kickoff deck.
Fixed-scope web development engagements scoped to your complexity. Smaller features and internal tools often land in 2 to 6 weeks; multi-module platforms take 6 to 12 weeks. If you are still validating a single idea, start with MVP development services instead.
01 / SCOPE
What custom software development covers
Business web apps
Client portals, ops dashboards, approval workflows
Internal tools
Replacing spreadsheet sprawl, admin panels, data entry UIs
SaaS platforms
Multi-tenant products with auth, billing, and role-based access
Integrations
Connecting your app to CRMs, payment rails, legacy APIs
Product extensions
New modules on an existing codebase you own
Web development is the default delivery surface: responsive frontends, API backends, databases, and deployment. When mobile is required, I use React Native and Expo against the same backend.
02 / APPROACH
Custom software vs off-the-shelf
Approach
When it wins
Trade-off
Approach
Off-the-shelf SaaS
When it wins
Standard workflow, no differentiation
Trade-off
You adapt to their product shape
Approach
No-code / low-code
When it wins
Fast internal prototype
Trade-off
Hard to extend; weak on custom logic
Approach
Custom software development
When it wins
Your workflow is the product
Trade-off
Takes weeks, but you own the result
If your edge lives in a specific flow: how data moves, how users collaborate, how pricing works: custom development is usually the right call. If a $20/month tool already does 90% of the job, I will tell you to buy it.
03 / DELIVERABLES
What you get
Requirements lock
Written scope, timeline, and fixed price before build
Design + build
UI, backend API, database, auth as needed
Web development
Production-ready frontend: React, Astro, or your stack
Deployment
Live on Railway, Vercel, AWS, or your cloud
Handover
Source in your repo, setup docs, walkthrough
Communication
Async updates or calls: you talk to the person writing code
04 / PROCESS
How I work
02
Written scope
Features, milestones, fixed quote.
03
Build and ship
Iterative delivery with regular check-ins.
04
Handover
Deployed product, documentation, optional follow-on support.
I quote fixed-price, fixed-scope for defined builds. Open-ended retainers are available for ongoing product work after the first release.
05 / STACK
Technology stack
Frontend
React, Next.js, Astro, TypeScript
Backend
Python (FastAPI, Django), Node, Go, Java Spring Boot
Data
PostgreSQL, Redis, object storage
Default web stack: React + FastAPI + Postgres. If you have an existing codebase, I work inside it. Greenfield projects get a stack chosen for maintainability and hiring, not novelty.

07 / FIT
Who this is for
GOOD FIT
- You have validated demand and need v1.1, not another prototype
- A spreadsheet or manual process is costing real hours every week
- You need a web app that off-the-shelf tools cannot express
- You want one developer, not a ten-person agency roster
NOT A FIT
- You have not validated the core idea yet (MVP development is the better entry)
- You need compliance-heavy enterprise rollout on day one without phased delivery
- You want the cheapest hourly rate with no scope definition
08 / FAQ
FAQ
01
How is this different from your MVP service?
MVP development is scoped to validate one core idea fast, with fixed-scope packages. Custom software development covers fuller products, internal tools, and post-validation builds where the scope is wider and the timeline is longer.
02
Do I own the code?
Yes. Your repository, your IP, documented handover.
03
Can you work on our existing codebase?
Yes. I regularly extend existing React, Python, and Node codebases rather than starting greenfield.
04
How long does custom web development take?
2 to 12 weeks depending on scope. A focused internal tool can ship in 2 to 4 weeks; a multi-module SaaS platform typically needs 6 to 12.
05
Do you do mobile apps?
When needed, yes: usually React Native + Expo sharing a backend with the web app. Web-first remains the default recommendation unless the product is inherently mobile.
