About — PreetHari Inc | Full-Stack Developer, Toronto

Our Story

Built from 10+ Years in the Trenches

PreetHari Inc was founded by Gagandeep Singh — a developer with 10+ years of enterprise IT experience spanning government procurement platforms, Dynamics 365, Power Platform, full-stack web apps, mobile development, and test automation.

That career built real depth — including 2+ years building a procurement portal for Washington State government (Angular, SQL Server stored procedures, ngGrid), QA automation at scale, and a Guinness World Record for the largest TLD migration in internet history. PreetHari Inc was created to bring that same enterprise-grade thinking to businesses who couldn't otherwise access it.

Today PreetHari Inc has 5 live client projects delivered — websites and a Flutter mobile app — with 3 more actively in development. Quality and honesty over volume. Fully remote, serving clients across Canada.

How We Work

Our Principles

The beliefs that shape every engagement — from the first call to go-live and beyond.

Success isn't measured at go-live. It's measured 6 months later when your team still uses the system daily — not working around it. Everything we design starts with the end user in mind.

Fixed-scope proposals. Regular demos. Clear timelines. If scope needs to change, you hear it immediately — not on the invoice. We treat every budget as if it were our own.

End-users are involved in discovery, design, and testing — not just UAT at the end. The most technically perfect solution fails if the people who need to use it won't or can't.

We build for maintainability, not recurring billable hours. Clean code, full documentation, and knowledge transfer — so you're independent when the project ends, not dependent on us.

If a solution is wrong for you, we'll say so — even if that means losing the deal. We'd rather be trusted advisors than order-takers. That honesty is why clients come back.

We work efficiently remote — saving you meeting overhead and allowing async collaboration. We're Toronto-based and can meet in person when it genuinely matters.

The Team

Who You're Working With

One person, deep expertise — not a generalist agency with rotating junior staff.

Gagandeep Singh

Founder · Full-Stack Developer · Web & App Developer

10+ years building software — currently focused on websites, web apps, and SaaS products for businesses across Canada, alongside Flutter mobile apps, D365 implementations, and test automation. I've shipped production code ranging from trade business websites and SaaS platforms to government procurement portals, contributed to a Guinness World Record, and built apps people open every day.

PreetHari Inc brings that enterprise depth to businesses who need it without the enterprise price tag — or the layers of intermediaries that inflate the cost.

Common Questions

Frequently Asked Questions

What types of projects do you work on?

We specialize in Dynamics 365 & Power Platform solutions, custom web and mobile applications, system integrations, and QA automation. Whether you need a full application built from scratch or help enhancing an existing system, we can assist. Our sweet spot is mid-market businesses with complex operational needs.

How long does a typical project take?

It really depends on scope. A straightforward website or single integration might take 2–4 weeks, while a comprehensive Power Platform or Dynamics 365 solution could take 2–3 months. We provide a realistic timeline after a discovery call — no inflated estimates to pad the schedule.

Do you work remotely or on-site?

We primarily work remotely but are based in Toronto and available for occasional on-site meetings when needed. Remote-first allows us to collaborate efficiently regardless of your location — most of our clients find this more convenient, not less.

What happens after the project is complete?

We provide full documentation and hands-on training so your team can manage the solution independently. We're also available for ongoing support, bug fixes, and future enhancements. Many clients engage us for ongoing retainer support or phase two work — that's the relationship we aim to build.

How do you price your work?

Every project is unique. We provide fixed-scope proposals based on your specific requirements, timeline, and complexity. No hourly billing surprises. For ongoing support, we offer monthly retainer packages. The first consultation is always free.

Can you sign an NDA before we discuss our project?

Absolutely — we have NDAs available upon request and are happy to sign before any detailed conversation. Your business information and project details stay confidential.
