A senior app developer for construction

For construction, a browser app means one tool that project managers, site managers, subcontractors and clients can open anywhere: on site-office machines, tablets on site and clients on their own devices, with nothing to download and nothing to update through a store. That is what this service builds -- web apps, internal tools and portals -- and the distinction matters, because a store app is a different product with different skills, different approval, and different maintenance. This page is about the browser version only.

Today, in construction, snag lists, variations, delivery notes and safety paperwork living in separate folders, so a variation agreed on site never reaches the invoice. The records that should answer a simple question -- snag lists, variations, delivery schedules, safety records, subcontractor progress and client approvals -- live in too many places, so the answer comes from memory or from a phone call instead of from a system. The app earns its place by making that answer visible to the people who need it, on the machines they already have, in the middle of real work rather than in a demo.

Custom is not the default recommendation. If the project management tool, document storage and the accounting package already holds the process, keep them. Custom fits when the process keeps bending or breaking around generic tools, and the proof is a first slice: snag lists with variation approvals for one site. Talk through the fit first before scope is set, so the decision is based on the actual workflow, not a feature list.

What you get

What this engagement covers for construction

  • Workflow, mapped before screens — The process is mapped with the people who do it, including the exceptions, before any screen is designed. In construction that means walking through snag lists, variations, delivery notes and safety paperwork living in separate folders, so a variation agreed on site never reaches the invoice, and agreeing which step the app must handle first, rather than digitising a broken routine exactly as it stands.
  • The internal tool — A site board: open snags, deliveries due, variations awaiting approval and safety actions outstanding. It is built for the team itself: the view that shows what needs attention today, who owns it, and what is overdue, on site-office machines, tablets on site and clients on their own devices, so the team stops digging through spreadsheets and chat threads to answer a simple status question.
  • The customer portal — A client portal where clients see progress, approve variations and download completion documents. Customers, clients or partners get a secure area of their own, so they stop phoning for status and the business stops answering the same question from three different inboxes. The portal shows the records that matter -- snag lists, variations, delivery schedules, safety records, subcontractor progress and client approvals -- and nothing it should not.
  • Connections to the systems you already run — The app reads and writes to the project management tool, document storage and the accounting package, instead of replacing tools the team already knows. Where a connection is not clean, that step stays manual with a named owner, rather than being silently dropped, so the app becomes part of the routine instead of another isolated record.
  • Permissions, records and audit — Project and subcontractor data stays in the firm's own accounts, with access per project and per role. Access is per role and per record, so people see the work they are responsible for and nothing else, and important changes carry who made them and when. That record is what makes the app trustworthy when a client, a regulator or a manager asks what happened.
  • Handover, not dependence — The code, the data and a plain guide to running and changing the app are handed over in the business's own accounts, so the business is not dependent on one person to keep it alive. The next maintainer can change the snag lists workflow without starting over, and ongoing support is optional, not a hostage arrangement.
Working in construction

Built around the systems construction already runs

The stack is a modern web framework, a database for the business's records, and hosting that the business owns. For construction, that matters because the users are on site-office machines, tablets on site and clients on their own devices: the app is tested on the machines and connections the team actually has, with simple screens and short forms, not on ideal ones in a demo room. Nothing is installed from a store, so there is nothing for users to update and nothing for an app-store review to block.

Code and hosting live in the business's own accounts, and the rollout is shaped by a real constraint: one site pilots it for snagging and variations before it is rolled out to other sites. That pilot is also where the main risk is caught early. A snag tool that records defects but never routes them to the subcontractor who has to fix them, so the list grows and nothing closes. A tool that ignores that failure mode looks finished at launch and fails in use, so the pilot runs on real work, with the people who will use it daily, before it replaces the old way of doing things.

How it works

From kickoff to delivery for construction

  1. Map the workflow

    The process, its users and its exceptions are mapped with the people who live it -- in construction, that means facing snag lists, variations, delivery notes and safety paperwork living in separate folders, so a variation agreed on site never reaches the invoice directly -- and the scope is set to the job that matters most.

  2. Prototype the screens

    The key screens are sketched and walked through with real users, so misunderstandings about snag lists, variations, delivery schedules, safety records, subcontractor progress and client approvals are found while they are still cheap to fix, not after the build.

  3. Build in slices

    The app is built working slice by working slice, starting with snag lists with variation approvals for one site, each slice usable and tested, rather than as one large delivery at the end that nobody can judge until it is too late.

  4. Pilot, then hand over

    One site pilots it for snagging and variations before it is rolled out to other sites, rough edges are fixed on real work, and the code, data and guide are handed over in the business's own accounts.

Why Omer

Why hire Omer

  • Workflow before code: The process is mapped with its real users first, so the app is built around snag lists, variations, delivery schedules, safety records, subcontractor progress and client approvals and the work behind them, rather than around a guess about what construction needs.
  • Usable slices, not a big reveal: Working parts arrive early, starting with snag lists with variation approvals for one site, and are tested by the people who will use them, so surprises stay small and the scope stays honest.
  • Built for real devices: The app is tested on site-office machines, tablets on site and clients on their own devices, on the connections the team actually has, because a tool that only works in the office is not a tool for construction.
  • Your code, your data: Code, hosting and data belong to the business, documented for whoever maintains the app next -- and project and subcontractor data stays in the firm's own accounts, with access per project and per role.
  • No store, no install: Because the app runs in a browser, there is nothing for users to download, update or get approved by a store, which matters most when project managers, site managers, subcontractors and clients change often or share devices.
FAQ

Questions, answered

How is a browser app different from a store app for construction?
A browser app runs on the web on any device with nothing to install, while a store app is built for phones, distributed through app stores and uses phone features. For construction, the browser version fits when project managers, site managers, subcontractors and clients work on site-office machines, tablets on site and clients on their own devices. If the job truly needs phone-only features or store distribution, that is the mobile-app build instead, and it is named as such rather than stretched into this one.
Do we need a custom app, or would a generic tool do for construction?
That is the first question, and it is answered honestly. If the project management tool, document storage and the accounting package already holds the process, keep them. Custom earns its place when snag lists, variations, delivery notes and safety paperwork living in separate folders, so a variation agreed on site never reaches the invoice, and the test is a single slice -- snag lists with variation approvals for one site -- built and used before any larger commitment.
How are variations handled so they actually get paid?
As a controlled record, not a site conversation. A variation is raised in the app, priced, approved by the client in the portal, and only then does it flow into the job record and the invoice. Unapproved work stays visible as unapproved, so nobody discovers it at final account stage.
Who owns the app and its data?
The business does: the code, the data and the hosting accounts, with documentation for the next maintainer. Nothing is held back to force ongoing payments, and the records the app holds -- snag lists, variations, delivery schedules, safety records, subcontractor progress and client approvals -- stay in the business's own accounts under its own access rules.
How is the app tested before it replaces the old routine?
With the people who will use it, on their real work, during a pilot before it replaces the old routine: one site pilots it for snagging and variations before it is rolled out to other sites. Their feedback fixes the rough edges while fixes are still cheap, and the pilot is judged on whether the snag lists workflow actually improves, not on whether the screens look finished.
