SERVICE 01

Custom Software Development

Custom software development and web development for products past the MVP stage: internal tools, SaaS platforms, dashboards, and business web apps. One developer, fixed scope.

$2,000 to $15,000+

Typical project range

2 to 12 weeks

Typical delivery window

1 developer

You talk to who builds it

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 from roughly $2,000 to $15,000+, depending on 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

01

Discovery

You describe the problem, users, and constraints (email or 30-min call).

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.

I am Ekky Armandi, a self-taught engineer with 5+ years of client delivery (Upwork profile).

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

09 / FAQ

FAQ

01

How is this different from your MVP service?

MVP development is scoped to validate one core idea fast, with packages from $800. 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.
