Legacy System Modernization Company in Seattle

QServices is a remote-first software consultancy serving Seattle businesses in tech, cloud, aerospace, and retail on legacy system modernization engagements, with roughly three hours of Pacific Time overlap each morning. We are India-based, not Seattle-based. See our services hub for the full scope of what we deliver.

What Seattle buyers typically need from Legacy System Modernization

Seattle's economy spans tech companies, cloud infrastructure providers, aerospace manufacturers, and large retailers. The modernization problems we see across those sectors:

• Tech and cloud companies running .NET Framework or Java EE monoliths that can no longer ship features at the pace product teams require.
• Aerospace suppliers and manufacturers with VB.NET or legacy Windows-based systems where retiring engineers carry the institutional knowledge and no replacement documentation exists.
• Retail businesses that need to move off on-premise infrastructure onto Azure to handle peak-season elasticity without rebuilding the entire platform at once.
• Companies handling consumer health data subject to the Washington My Health My Data Act, which places consumer consent and data-residency obligations on systems that were never built with those constraints in mind.

The right migration approach depends on risk tolerance. Aerospace systems and regulated-data platforms almost always need a strangler-fig migration: the old system stays live, new modules run alongside it, and traffic is cut over incrementally. A big-bang rewrite in these environments is one of the most common failure patterns we are specifically hired to avoid.

How we work with Seattle clients

India Standard Time is 12.5 hours ahead of Pacific Daylight Time (13.5 hours ahead during Pacific Standard Time). That is a real gap, and we do not pretend otherwise.

Our team blocks a daily overlap window from approximately 8 AM to 11 AM PT, when engineers in India extend their day into the evening to run standups, sprint reviews, and architecture discussions in real time. Outside that window, every decision is logged in Slack or Microsoft Teams so your team can review outcomes the next morning without waiting on a reply from India.

For milestone reviews (end of sprint, architecture sign-off, go-live approval), we schedule dedicated two-hour calls in the PT morning window. Code lives in a client-owned Git repository with daily commit history visible to your team at any time. On-site visits to Seattle are available for project kickoff or critical milestone reviews on engagements of three months or longer.

Relevant work in similar markets

We do not have a published case study from a Seattle-headquartered client. The closest work we can point to honestly:

Global EHS Platform Modernization (manufacturing and safety compliance): We rewrote a legacy VB.NET monolith for a global Environmental Health and Safety software company into .NET 8 and React on Azure. The platform covered Management of Change, Incidents and Events, LMS training, and automated scheduling. Aerospace and industrial companies in the Seattle area run comparable compliance-sensitive, multi-module systems. The outcome was improved scalability and maintainability after years of accumulated technical debt in the old codebase.

Investment Analytics Platform (financial services): We replaced a spreadsheet-based stock analytics workflow with a role-authenticated Azure dashboard with automated scraping and real-time financial metrics. Applicable to Seattle-area retail and financial-services companies still running business logic in Excel or legacy Access databases.

What Legacy System Modernization costs for a typical Seattle project

All pricing is in USD. Typical brackets for Seattle-based engagements:

• Assessment and roadmap ($8,000–$30,000): Architecture review, strangler-fig migration plan, integration surface mapping, and risk register. Standard starting point before committing to a full program.
• Module extraction or API gateway layer ($30,000–$120,000): Pulling one or two bounded contexts out of a monolith and placing them behind an API gateway. A practical first increment for Seattle tech companies with near-term delivery pressure.
• Full platform modernization ($120,000–$500,000): Multi-phase migration over 16–52 weeks, moving a VB.NET or .NET Framework monolith to .NET 8 on Azure with Docker containerization.

Work that touches Washington My Health My Data Act compliance adds 15–25 percent for the additional governance, documentation, and architecture review that regulated scope requires. Each non-trivial third-party integration adds $3,000–$12,000. See our Legacy Modernization pricing page for full detail, and our manufacturing and industrial modernization work for an industry-adjacent reference.

How to start working with us

Three steps from inquiry to active project:

1. Discovery call (30 minutes): We review your current stack, the business drivers for modernizing, and whether a strangler-fig or module-extraction approach fits your constraints.
2. Scoping document: Within five business days we deliver a written scope covering phases, milestones, team composition, and a cost range.
3. Project start: Contracts, repository access, and kickoff. For Seattle clients the kickoff call is scheduled in the 8–11 AM PT overlap window.

Can you work with Seattle companies as a remote vendor?

Yes. All our US engagements are remote. Code is in a client-owned repository. Standups run in the 8–11 AM PT daily overlap window via Microsoft Teams or Slack. Every decision is documented in writing, which matters for Seattle companies whose legal work falls under WSBA oversight and who need a clear change-management record for regulated projects.

For scope touching the Washington My Health My Data Act, we configure Azure data residency at the infrastructure level from day one and can provide architecture documentation suitable for a third-party compliance review. This is an architecture and governance decision made at project kickoff, not something retrofitted at the end.
