.NET Development Company in Seattle

QServices is not headquartered in Seattle, but we work with Seattle clients across tech, cloud, aerospace, and retail on remote .NET development engagements with Pacific Time hours overlap. QServices is a remote-first software consultancy serving Washington State businesses that need custom .NET 8+ applications, APIs, and Azure-deployed services built to production standards.

What Seattle buyers typically need from .NET development

Seattle's software market is shaped by proximity to Microsoft in Redmond and Amazon's platform engineering teams downtown. Companies here often need engineers who understand .NET at the infrastructure level, not just the application layer. Common project types in Seattle-area markets:

• Tech companies: RESTful APIs and microservices on Azure App Service, often replacing legacy SOAP or on-prem Windows services
• Cloud product teams: .NET 8 worker services integrated with Azure Service Bus, Event Grid, or SQL Server on Azure
• Retail backends: order management APIs, inventory sync layers, and integration bridges between ERP systems and e-commerce platforms
• Aerospace tooling: internal workflow applications and data pipeline services with auditable SQL Server backends

One compliance requirement specific to Washington State: the Washington My Health My Data Act (WMHMDA) applies to any consumer-facing application that collects or shares health data for Washington residents. It requires granular consent logging, the right to deletion, and disclosure standards stricter than HIPAA in several areas. Any .NET application in healthcare-adjacent tech built for a Washington company needs architecture that supports these workflows from day one. We scope this requirement explicitly when it applies.

How we work with Seattle clients

Our engineering team is based in India (IST, UTC+5:30). Seattle runs Pacific Time (UTC-7 in summer, UTC-8 in winter). The gap is 12.5 to 13.5 hours. That is a real constraint and we do not minimize it.

What we do instead is structure the engagement so the gap does not create blockers. Our engineers start early IST and Seattle leads join a standing 30-minute standup between 8 and 10 AM PT, which is 8:30 to 10:30 PM IST on our side. Code reviews happen overnight from Seattle's perspective, so pull requests are annotated and ready before your team arrives each morning.

Week-to-week communication model:

• Daily 30-minute standup via Microsoft Teams or Slack Huddle at a time your team sets
• Async Slack channel with a written end-of-day summary from our engineers
• Pull requests reviewed within 12 hours, with written inline comments on every change
• Sprint-end demos via live screen share or Loom recording
• On-site visits to Seattle available for project kickoff or major milestone reviews on request

We default to Microsoft Teams, GitHub, and Azure DevOps. If your Seattle team is already on those tools, there is nothing new to adopt.

Relevant work in similar markets

We do not have a published case study from a Seattle client. The closest work we can point to is in FinTech and payments, which shares the API complexity, data integrity requirements, and integration depth common in Seattle's tech and cloud sectors. It is not a direct match for aerospace or retail, and we say so plainly.

For SomBank, an Islamic bank in Somalia, we built a full mobile payment platform on .NET, Azure Service Bus, Azure B2C, and an Ocelot API Gateway. The platform launched with 100,000-plus downloads and a 4.8-star rating. The architecture required multi-layer authentication, real-time transaction routing, and strict API contract documentation throughout.

For Varipay, a cross-border payments aggregator in Jamaica, we built a microservices gateway integrating Stripe, PayPal, Wise, and regional processors. Transaction fees dropped approximately 30% through optimized routing and settlement times went from 3-5 days to under 24 hours. This was .NET microservices work end to end, with documented REST contracts on every interface.

If your project is in aerospace tooling or retail systems, we do not have a matched portfolio piece to show. What we can demonstrate is the engineering discipline: API-first design, CI/CD from day one, no skipping database design.

What .NET development costs for a typical Seattle project

All engagements are priced in USD. Seattle projects typically fall in the medium to large bracket. Our hourly rates run from $20 to $65 depending on seniority.

• Small scope ($2,000-$8,000, 80-200 hours): a single API service, one module migration from legacy .NET Framework, or a single system integration
• Medium scope ($8,000-$30,000, 200-600 hours): a full backend application with authentication, Entity Framework data layer, SQL Server, and 2-3 integrations
• Large scope ($30,000-$120,000, 600-2,000 hours): a multi-service platform with CI/CD pipelines, staging environments, and ongoing sprint delivery over 3-6 months
• Platform scope ($120,000-$400,000, 2,000-6,000 hours): greenfield enterprise products or full legacy modernization programs

For projects subject to the Washington My Health My Data Act, add 15-25% for compliance architecture and consent management design. Each non-trivial system integration (ERP, identity provider, payment gateway) typically adds $3,000-$12,000 to scope.

How to start working with us

Three steps from first contact to project start:

1. Discovery call (30 minutes): We learn what you are building, what is already in place, and what the timeline pressure looks like. No pitch, just scoping questions.
2. Scoping document: Within 3 business days, we send a written summary of the proposed approach, a timeline estimate (typically 8-24 weeks), and a fixed or time-and-materials quote.
3. Project start: Once terms are agreed, we assign a lead .NET engineer and schedule the kickoff call within two weeks.

Use the contact form below to book a discovery call or send a brief description of your project.

Do you work with Seattle companies remotely?

Yes. We have no Seattle office. All engagements run fully remote with a daily overlap window in the morning PT time zone. We use Microsoft Teams or Slack for communication, GitHub for code review, and Azure DevOps or GitHub Actions for CI/CD pipelines, tools Seattle engineering teams typically already use.

For data residency: Washington State companies that need application data stored within the United States can specify Azure's West US 2 region, located in Redmond, WA, as the deployment target. We document the data residency decision in the scoping document before any work begins, so there is no ambiguity when the application goes to compliance review. For full platform documentation, see the official Microsoft .NET documentation.
