Build Flows

Custom applications and portals

Custom apps and portals for when off-the-shelf software does not fit

Some workflows do not fit Procore, your ERP or a spreadsheet, and forcing them in costs time every week. We build focused applications and portals around that workflow, connected to your existing systems, with roles, secure sharing and an audit trail. Connect, the multi-agent scheduling platform we built for Syncify, is one example running in production.

The value it creates

  • Time saved

    Fewer handoffs and re-keyed data

    An app built around the workflow pulls data from the systems that already hold it and captures new inputs once, instead of copying between email, spreadsheets and portals.

  • Standardization

    The process runs the same way every time

    Steps, required fields and approvals live in the application, so every project follows the same procedure no matter who runs it.

  • Collective intelligence

    Clients and owners in the same record

    Secure links and portals let clients answer questions directly, with answers stored in the record and marked as client verified, as in Connect.

  • Visibility

    See status without asking for it

    Dashboards and admin views show what is open, who owns it and what changed, from portfolio down to a single item.

  • Better decisions

    Decisions backed by a history

    Version history and audit trails show who changed what and when, so a decision can be defended with the record rather than memory.

  • Cost saved

    Own what you build

    A focused application can replace a costly workaround or a tool you only half use, and the code is yours to keep and extend.

What we build

  • Workflow platforms

    Multi-step applications that turn a team's standard procedure into guided steps, such as Connect, which takes schedulers from project documents to a reviewed CPM schedule.

  • Client and owner portals

    Portals and password-protected share links where clients answer questions, review updates and confirm requests, with timestamps and history on both sides.

  • Admin portals

    Admin views for workspaces, roles, feature flags, configuration and usage, like the executive admin portal that governs the agents in Connect.

  • Internal tools

    Focused tools for one job, such as a structured input form, an approval queue or a data-quality review screen, that replace a shared spreadsheet.

  • Field and mobile capture

    Mobile-friendly screens for checklists, photos, video and audio on site, tied back to the project, as in the Connect job walk feature.

  • AI-enabled applications

    Applications with agents built in, such as Construct.Chat, where users create agents, give them MCP tools against Procore and inspect every tool call.

  • Embedded apps and extensions

    Applications that sit next to a system you already use and add what it lacks, the way Connect works on top of the Syncify scheduling engine instead of rebuilding a Gantt chart.

  • Access control and audit

    Sign-in, workspace roles such as admin, member and guest, per-feature switches and a recorded history of changes.

How it works

App architecture: users with defined roles use the app's portal, workflows and screens, which go through an API with authentication to a data layer of your existing systems plus the lakehouse, with audit logging and monitoring across all of it.
  1. 1.Users & roles

    Staff, subs and clients each see only what their role allows.

  2. 2.App

    Portal, workflows and screens built around your process.

  3. 3.API & auth

    Sign-in and access rules enforced on every request.

  4. 4.Data layer

    Your existing systems plus the lakehouse.

  5. 5.Audit & monitoring

    Who did what, when — and alerts if something breaks.

  1. 1

    Check whether you need custom software

    We start with the workflow, the people who run it and the tools you already own. If configuration, an integration or an automation covers it, we recommend that instead.

  2. 2

    Define users, roles and data

    We agree who uses the application, what each role can see and change, which systems it reads from and writes to, and what must be recorded.

  3. 3

    Build in short, reviewable increments

    We build on a common stack, typically Next.js and TypeScript for the application and Python for data and agent work, and show working screens early so feedback lands before the design is fixed.

  4. 4

    Connect and secure it

    We integrate with your systems through their APIs, apply least-privilege access, and add version history and audit logging where decisions are made.

  5. 5

    Launch, measure and hand over

    We launch to a first group of users, compare the workflow against its baseline, and hand over code, documentation and admin access you control.

Systems we work with

  • Next.js
  • TypeScript
  • Python
  • Procore
  • Syncify
  • Oracle Primavera P6 and XER files
  • Model Context Protocol (MCP)
  • Microsoft Azure
  • SharePoint

How we measure the value

We agree a baseline before we build and measure the same things after go-live. Use the monthly report cost calculator to put your own numbers on it.

What we measureHow baseline and after are captured
Time to complete the workflowWe time a sample of the workflow done the current way before the build, then the same workflow in the application after launch.
Handoffs and re-keyed fieldsWe map each copy, paste and email handoff in the current process, then count how many remain once the application is in use.
Client response time on requestsWe compare how long client answers take by email today with the time from sending a portal link to a client-verified answer.
Revision rounds and reworkVersion history records how many drafts it takes to reach an approved output, compared with the rounds on recent projects done the old way.
Adoption by roleUsage tracking shows active users and completed workflows per role from launch, so we can see whether the application replaced the old process.

Use cases

Frequently asked questions

When does a custom application make sense instead of off-the-shelf software?

When a workflow is central to how you work, runs often, and does not fit the tools you own without spreadsheets and re-keying around it. If configuration, an integration or an automation solves it, we will say so and recommend that instead. Custom software is worth it when the workaround costs more than building and maintaining the application.

Will a custom app replace Procore or our ERP?

Usually not. We build alongside the systems of record and connect to them through their APIs. Connect, for example, works on top of the Syncify scheduling engine and imports schedules into it rather than rebuilding a Gantt chart.

Can clients and owners use the application without an account?

Yes, where it fits. Connect lets a scheduler send a secure, password-protected link so the client can answer questions directly, and the answer is stored with a timestamp and marked as client verified. For ongoing access we set up guest roles with limited permissions.

What technology do you build on?

Typically Next.js and TypeScript for the application, and Python for data pipelines, integrations and agent work, hosted in your cloud or a managed environment agreed during discovery. We choose boring, well-supported tools so another team can maintain the code.

Who owns the code and the data?

Ownership, hosting and handover terms are agreed before the build starts. We design for you to hold the code, the data and the admin access, with documentation so the application is not tied to us.

How is a custom build priced?

Each build has a fixed scope and price, agreed after discovery. Many start with an integration sprint or an AI readiness review to confirm the workflow, the data and the users before the application is scoped.
