Enterprise Software Development Company in Seattle

We give ranges and then quote a fixed fee against a signed statement of work. A proof of concept or architecture spike, meaning a working thin slice through the real integration points with a load test and a written architecture decision record set, typically runs USD 60,000 to 150,000 over six to twelve weeks. A production enterprise application with three to six integrations, an identity and authorisation model, a data platform component, observability and a documented operational handover typically runs USD 250,000 to 900,000. A multi-year platform programme replacing a legacy system of record, with parallel running, event architecture, a migration path for years of historical data and a real change management workstream, runs USD 900,000 to 4,000,000 and up. Seattle senior engineering rates are among the highest in North America because Amazon, Microsoft and Boeing set the local compensation floor and every startup here competes against those packages. Delivering from Edmonton and Chandigarh removes that premium without shifting the working day, since Edmonton sits one hour ahead of Seattle on Mountain Time. Cloud consumption, third-party licences and security tooling are billed at cost and are not in those figures.

Washington has not enacted a comprehensive consumer privacy statute. HB 1671, a comprehensive personal data privacy bill, was introduced in 2025 and has sat in House Appropriations since February 2025 without passing. What applies instead is domain-specific and, in places, stricter than a general privacy law would be. Health systems fall under HIPAA and Washington's Uniform Health Care Information Act at RCW 70.02. Any platform touching consumer health data, including inferences, falls under the My Health My Data Act, HB 1155, signed April 27 2023, which makes a violation a per se violation of the Consumer Protection Act at RCW 19.86 and carries a private right of action. Biometric identifiers enrolled for commercial purposes fall under RCW 19.375. Financial institutions fall under GLBA and the Safeguards Rule. Educational records at the University of Washington and school districts fall under FERPA. Anything touching criminal justice information falls under the FBI CJIS Security Policy. Breach notification runs on a thirty calendar day clock under RCW 19.255.010, with Attorney General notification required within thirty days when more than 500 Washington residents are affected. Public agency systems add public records obligations under RCW 42.56.

By strangling it, and by refusing to move the business and the technology at the same time. The pattern we use is a facade in front of the legacy system that routes traffic by capability, so functionality moves across in slices while the old system keeps serving everything else. The first slice is always chosen for low blast radius and high learning value, not for business excitement. Before any code moves we build a characterisation test suite against the legacy system's actual observed behaviour, including the behaviour nobody intended, because in a twenty-year-old mainframe batch or .NET Framework monolith the bugs are load-bearing. Data is handled by change data capture into the new store with dual-write or dual-read verification running for weeks before any read cuts over, and reconciliation jobs comparing balances and counts on a schedule. Every slice ships behind a feature flag with a tested rollback and a defined error budget. We do not accept a project shape where the switch is thrown on a single weekend eighteen months from kickoff, because there is no way to test the assumption that the whole thing works until it is far too late to do anything about it.

Yes, and public sector work has requirements that commercial buyers rarely carry. Washington state agency systems fall under WaTech policy and standards, and where generative AI is involved they fall under Executive Order 24-01, signed January 30 2024, which directs agencies to inventory generative AI use, develop procurement guidance and produce risk assessments for high-risk generative AI systems anchored to the National Institute of Standards and Technology AI Risk Management Framework. SB 5838, signed March 18 2024 as Chapter 163, Laws of 2024, created the state artificial intelligence task force whose recommendations shape where that policy goes next. City of Seattle projects that collect data about the public go through the Surveillance Impact Report process, reviewed by the Surveillance Advisory Working Group, before acquisition. Anything touching criminal justice information falls under the FBI CJIS Security Policy, which drives advanced authentication, personnel screening and audit requirements into the design. Every public agency system also inherits Public Records Act obligations under RCW 42.56, which means retention, export and redaction have to be built features rather than manual processes. Accessibility to WCAG 2.1 AA is a contractual requirement, not a nice-to-have.

Usually whichever one your identity and data already live in, because the integration cost of splitting them exceeds any pricing advantage. In practice Puget Sound skews harder toward Azure than the national average, since Microsoft Entra ID, Microsoft 365 and Power BI are already deployed at most large local employers and the regional talent pool is deep in .NET. Azure West US 2 is physically located in Washington State, which gives the lowest latency for a Seattle user base and keeps data inside state lines when that matters. AWS is equally native here for obvious reasons, and us-west-2 (Oregon) is one of the most feature-complete regions Amazon operates, with us-west-1 (N. California) as the pairing for cross-region resilience. GCP us-west1 (Oregon) is the sensible choice for shops standardised on BigQuery or Vertex AI. We build infrastructure with Terraform and keep the application layer on portable primitives, containers, Postgres-compatible databases and OpenTelemetry, so a future move is expensive rather than impossible. Regulated and government workloads go to AWS GovCloud (US-West) or Azure Government. We will tell you when a multi-cloud strategy is costing you more than it protects you from.

By treating the time difference as a schedule, not an inconvenience, and by being straightforward about what we are. Codazz has no Seattle office. Our engineers work from Edmonton, Alberta and Chandigarh, India, and we say so before anyone signs anything. Edmonton is on Mountain Time, one hour ahead of Pacific, which is the smallest offset any offshore or nearshore arrangement can give a Seattle buyer. A 9:00 AM Pacific standup is 10:00 AM for us. A 2:00 PM Pacific demo is 3:00 PM. There is no window where your architect is asleep during your working day. Chandigarh covers the Seattle overnight, which we use deliberately: builds, data loads, load tests and regression suites run while Seattle sleeps, so Pacific mornings open with results rather than a queue. Alberta shares a business and legal culture with the Pacific Northwest, which shortens contracting. For anything requiring on-site presence, a fabrication floor walk, a data centre visit or a workshop, we travel. Everything else runs through the same tooling your internal teams already use, in your repositories, with your review process.
