Proven .NET success stories

Client

Jewelers Mutual

Industry

Insurance & Jewelry Retail Services

Portal-driven precision for jewelry warranty management

The challenge: Managing sales and jewelry warranty plans involved a fragmented process with limited visibility across roles. The lack of a centralised system made it difficult to monitor the warranty lifecycle and enforce role-based privileges effectively.

Client

ClubRunner

Industry

Membership & Club Management Software

Modernising ClubRunner’s CMS for scale, speed & style

The challenge: With a user base of 5,000+ clubs worldwide, ClubRunner needed to overhaul its legacy content management system to stay competitive and agile. Their goals were twofold: upgrade to modern technologies for long-term scalability and introduce customisable, visually engaging themes to enhance user experience. Additionally, transitioning to cloud infrastructure was critical to support global access and performance demands.

Client

Grasshopper Energy

Industry

Clean Tech & Renewable Energy

Scalable ERP & CRM platform fuels solar growth at Grasshopper Energy

The challenge: As Canada's leading integrated solar energy provider, Grasshopper Energy needed a centralised digital backbone to support its rapid growth. Operations were siloed, sales processes were inconsistent, and project visibility was limited across departments. The company required a unified system to manage everything from lead generation and project estimation to installation tracking and long-term asset management.

Client

QuickContractors.com

Industry

Construction & service marketplace

Scaling a startup into a national contractor marketplace

The challenge: Back in 2005, QuickContractors.com set out to digitally connect homeowners with reliable contractors. Their early platform, built in Classic ASP, was designed for simple service requests and scheduling. As the company grew, securing partnerships with Home Depot, Lowe’s, and other major retailers. The legacy system couldn’t keep up with the demand for logistics, dispatching, and real-time coordination.

Have
questions?

You’re not alone! This section covers the most common queries we receive, giving you quick, clear answers to help you understand our services and how we work.

Our core schedule follows Pakistan Standard Time (GMT + 5). You’ll always have at least four hours of overlap with your local workday—whether you’re in Australia, Europe, or North America—for daily stand‑ups and real‑time collaboration.

We’re tool‑agnostic. Most clients add us to Jira or Trello, while others prefer Monday.com, Basecamp, Azure DevOps, or ClickUp. Slack or Microsoft Teams is our default chat channel, but we’ll work inside whichever stack you already use.

Yes. On Hourly and Monthly plans you have direct one‑to‑one access to each developer via chat or video. For fixed‑scope projects, a dedicated Tech Lead is your main contact, yet you can still hop on calls with individual engineers whenever needed.

Absolutely. We sign a mutual NDA before any information is shared and include strict IP‑transfer clauses in our Master Services Agreement. All code lives in private repositories you own, protected by MFA and role‑based access.

Once the NDA is signed and the kick‑off deposit received, onboarding usually begins within 15 business days—often sooner for Hourly engagements.

All work goes through peer review and automated checks—SonarQube, unit and integration tests, security linting—inside a CI/CD pipeline before merging to your branch. You also receive test‑coverage and performance reports at each milestone.

Agile Scrum by default—two‑week sprints, Jira boards, sprint demos, and retros. If you prefer Kanban or a hybrid approach, we’ll align with your internal process.

Yes. Every Fixed‑Scope project includes 30 days of free warranty support, and you can extend coverage with a month‑to‑month Maintenance & Support plan.
