Data Function

Custom software development: Software built around how your business actually works

Spreadsheets emailed around, a report that takes two days, equipment nobody can see from the office. We turn that into a system your team uses every day, and we keep it running for years.

What we build

From a focused tool to a full platform

  • Web applications and portals

    Operations software, customer and partner portals, admin panels with roles and approvals, dashboards and reporting.

  • Mobile apps

    React Native apps for iOS and Android, published to the App Store and Google Play, with push notifications.

  • SaaS and MVPs for startups

    A first version that proves the model in weeks, built on a stack that scales to the next three years.

  • CRM and ERP systems

    Inventory, orders, logistics, finance and staff in one system, with per-page permissions and multi-language support.

  • Integrations and APIs

    REST APIs, payments (Stripe, Interac), telephony (Twilio, 3CX), accounting tools and legacy systems.

  • IoT and real-time data

    Device ingestion over MQTT and EMQX brokers, time-series storage, alarms and live dashboards for field equipment.

Proof

In production, with real users

All work

The performance dashboard developed by Data Function provides real-time insights into every solar site we manage. The system is simple, powerful, and beautifully executed.

How a project runs

Short phases with a review at every gate

  1. 01

    Discovery

    A free 30-minute call, then a short discovery phase: users, goals, data, constraints and what success looks like.

  2. 02

    Design

    Information architecture, wireframes and a design system before code, reviewed with you at each gate.

  3. 03

    Build & launch

    Engineering in short iterations with automated tests, accessibility and performance checks, then a planned launch.

  4. 04

    Run & improve

    We host, monitor, patch and keep improving. Documentation and training mean your team is never locked in.

Built to the rules you answer to

  • Security guidelines applied on every project: role-based access, encryption in transit and at rest, audited dependencies
  • Data hosted and processed in the region you are compliant with, including Canada
  • Accessibility to AODA and WCAG 2 on every interface people use
  • Compliance with local law (PIPEDA, PHIPA, CASL) designed in, not bolted on

Technology and ownership

Standard open-source technology, your own repository and hosting account, and documentation so any developer could take over.

  • React, Next.js and TypeScript
  • React Native (Expo)
  • Django REST Framework, Node.js
  • PostgreSQL, MySQL, Redis
  • OpenSearch and Elasticsearch
  • MQTT / EMQX, RabbitMQ, SQS
  • Docker, AWS (ECS Fargate, RDS, S3)
  • GitHub Actions with keyless deploys

Questions

About custom projects

What kinds of projects do you take on?

Custom web platforms and portals, mobile apps, integrations and data pipelines, AI assistants that answer from your own content, and websites from a small-business site to a full institutional redesign. We also take over and stabilize existing systems.

How does a project start?

With a free 30-minute discovery call. We listen to the problem, ask about users, data and constraints, and tell you honestly whether we are the right fit. If we are, you get a written proposal with scope, timeline and price before any work starts.

How long does a project take?

A standard website usually takes four to eight weeks. Custom software and AI projects run from a few weeks for a focused tool to several months for a full platform. Every proposal includes a timeline with review points.

Do you support software after launch?

Yes. We host, monitor, patch and improve the systems we build. Several client platforms have been in production with us for more than two years.

Where are you based, and who does the work?

We are a Toronto company working with clients across Canada and the USA. Senior people stay on your project from discovery to launch; there is no hand-off to a separate production team.

Do you use AI to build software?

We use modern AI-assisted tools to speed up development and raise quality. Every change is reviewed, tested and owned by a named engineer, and your code, content and accounts belong to you.

Bring us the problem, not a specification

A free 30-minute call is enough for us to tell you whether we are the right team, what we would build first and roughly what it would cost.
