Senior .NET Developer | C#, SQL Server & Mobile (MAUI/Xamarin)
Mesa, United States - 9:23 am local time
Clients come to me with a problem, not always a spec — and that's where I do my best work. I'm a full-stack .NET developer (C#, .NET Core, SQL Server, JavaScript) with 12+ years of experience translating what stakeholders actually need into practical, scalable solutions. I own the full lifecycle end-to-end, and I bring mobile (.NET MAUI/Xamarin) and data (Databricks, Kafka) skills when your project needs them.

Steps for completing your project

After purchasing the project, send requirements so Collis can start the project.

Delivery time starts when Collis receives requirements from you.

Collis works on your project following the steps below.

Revisions may occur after the delivery date.

Discovery & Requirements Confirmation

Review all client-provided materials, clarify any open questions, and confirm the final feature list, scope, and technical approach.

UI/UX Design Mock up

Create a visual mockup of the application (high-fidelity screens or clickable prototype) showing the full user interface and main flows — without backend functionality. Share this design preview with the client for review and feedback.

Review the work, release payment, and leave feedback to Collis.
