Web Development Company in Seattle

The figure moves with the build type: a scoped marketing or product website at Seattle rates, a custom commerce or booking platform (Shopify Hydrogen, commercetools, or Next.js plus Stripe), or enterprise web platforms with multi-region deployment, SSO, and compliance documentation. Scope drivers include design system, Next.js or Astro build, Core Web Vitals tuning, and WCAG 2.2 AA conformance. Seattle rates sit above Portland and Denver because of the Microsoft, Amazon, and Vercel talent premium across the Eastside. We give fixed-fee proposals rather than open time and materials estimates.

The My Health My Data Act (MHMDA), in effect since March 31, 2024 for most regulated entities, is one of the strictest US consumer health privacy laws and applies far beyond traditional HIPAA covered entities. It covers consumer health data broadly defined to include biometric, location around health facilities, mental health, reproductive, and wellness inferences. It requires opt-in consent, a consumer health data privacy policy, restricted geofencing around healthcare facilities, and a private right of action. If your site collects fitness, wellness, mental health, fertility, or location data on Washington residents, MHMDA likely applies. We run an applicability review in discovery and ship consent, data-minimisation, deletion, and access flows aligned with the Washington Attorney General's published guidance.

Yes. The Western District of Washington has an active ADA Title III plaintiffs' bar, and Seattle retailers, restaurants, and healthcare providers regularly face demand letters citing WCAG 2.1 or 2.2 conformance failures. Our standard build targets WCAG 2.2 AA, with axe-core, Lighthouse, and manual screen reader testing against NVDA, JAWS, and VoiceOver. We deliver a documented accessibility audit, a remediation log, and a published accessibility statement suitable for outside counsel. For clients with prior litigation history we coordinate with their ADA counsel on a structured negotiation path and ship a conformance roadmap that survives Department of Justice scrutiny.

Yes, within scope. For Boeing-adjacent suppliers selling into defense.gov vendor portals or handling Controlled Unclassified Information (CUI), we build web portals with CMMC 2.0 Level 2 controls aligned to NIST SP 800-171, including access controls, audit logging, FIPS 140-2 validated encryption, and US-person access restrictions for ITAR-controlled content. We deploy on AWS GovCloud (US-West) or Azure Government when CUI or ITAR data is in scope, keep all engineering work onshore for those engagements, and coordinate with a third-party CMMC C3PAO for formal assessment. Final ITAR registration and licensing stays with your trade compliance counsel.

Amazon and Starbucks engineering teams treat performance as a product metric, not a launch checklist. We follow the same discipline. Every build ships with a Core Web Vitals budget enforced in CI (Largest Contentful Paint under 2.0s, Interaction to Next Paint under 200ms, Cumulative Layout Shift under 0.05), Real User Monitoring through Vercel Speed Insights, Datadog RUM, or SpeedCurve, and a quarterly Lighthouse regression review. We use Next.js App Router with React Server Components, Astro islands for content sites, image optimisation through Cloudinary or next/image, and CloudFront or Vercel Edge for caching. We have moved Seattle retail clients from 30th to 90th percentile Core Web Vitals inside one quarter.

It depends on team and scale. For content-heavy retail and travel sites we recommend Sanity, Contentful, or Storyblok with Next.js or Astro, deployed on Vercel or AWS Amplify. For commerce, Shopify Hydrogen suits brands at USD $5M to $200M GMV that want headless speed without operating a full platform, commercetools or BigCommerce suit enterprise multi-brand catalogs, and a custom Next.js + Stripe + Algolia stack works for vertical-specific commerce (subscription, B2B, configurable products). For healthcare and wellness clients subject to MHMDA we typically self-host on AWS us-west-2 with a hardened CMS rather than relying on shared multi-tenant SaaS, because the consent and deletion guarantees are easier to evidence.

Yes. Many Seattle and Bellevue enterprises run identity through Microsoft Entra ID (formerly Azure AD), and we ship Next.js, .NET 8, and Blazor front ends that authenticate against Entra with OIDC, support conditional access policies, and federate with on-prem AD where needed. We integrate with SharePoint Online, Dynamics 365, and Microsoft Graph for customer and employee portals, and we have shipped Power Platform extensions where the existing M365 footprint makes that the right call. For multi-cloud clients we federate Entra with AWS IAM Identity Center so the same identity works across Azure West US 2 and AWS us-west-2 workloads.

A typical Seattle retail or commerce launch takes fourteen to twenty-two weeks from kickoff to production, assuming defined catalog and brand. Week 1 to 3 is discovery, regulatory review (MHMDA, CCPA, ADA), and design system. Week 4 to 12 is build, including Shopify Hydrogen or Next.js front end, payment and tax integration, search (Algolia or Constructor), and CMS migration. Week 13 to 18 is performance tuning to Core Web Vitals targets, accessibility audit, load testing for peak traffic, and security review. Week 19 to 22 is staged rollout with CloudFront warm-up and incident runbook. We have shipped to this cadence for retailers serving the Pacific Northwest and adjacent markets.
