Legacy and Modern .NET, Cloud, Web, and SQL Data Platforms

Building Reliable Software Across Legacy, Cloud, and Modern Web

From maintaining older .NET Framework applications to delivering modern .NET solutions, we design AWS and Azure architecture, build polished web interfaces with HTML, CSS, and JavaScript, and optimize SQL databases for performance, reliability, and long-term maintainability.

Based in Bellingham, WA, we support organizations throughout Whatcom and Skagit County with practical, low-risk development and modernization services tailored to your current systems.

Our Services

🛠

Legacy Application Maintenance

Ongoing bug fixes, performance tuning, and stability improvements for older business-critical systems, including legacy .NET and other inherited platforms.

Cloud Architecture & Delivery

Architecture planning and implementation for AWS and Azure: networking, environments, CI/CD flows, and infrastructure patterns that support growth without chaos.

🚀

Feature Development & Enhancements

Need new functionality in an existing app? We deliver backend and frontend enhancements that fit naturally into your current codebase without destabilizing what already works.

🗃

Data Platform & Migration Services

Schema design, query optimization, and migration planning across SQL Server and cloud data services, including moves from ad-hoc data stores to production-grade platforms.

🔒

Security Patching & Hardening

Legacy applications and cloud workloads are frequent targets. We audit, patch, and harden your systems against common vulnerabilities to keep data and users protected.

🔄

Incremental Modernization

Step-by-step migration paths — upgrading .NET Framework versions, moving to .NET 8+, replacing deprecated components — without a risky big-bang rewrite.

📈

Frontend Engineering (HTML, CSS & JavaScript)

Responsive layouts, accessible UI patterns, and maintainable component styling. We build and refine web frontends with semantic HTML, scalable CSS, and modern JavaScript interactions.

📝

Architecture Reviews & Technical Roadmaps

Inherited an undocumented codebase or unclear platform direction? We assess, document, and define practical roadmaps for application, cloud, and frontend evolution.

🔗

API & Third-Party Integrations

Connect your application to the tools and platforms your business already relies on — Google Calendar, Zapier, payment providers like Stripe and Authorize.Net, and more. We handle the plumbing so your systems work together seamlessly.

Architecture Decisions Backed by Delivery Experience

01

No Rewrite Pressure

We assess your application honestly. If maintenance is the right call, we say so. If a modern rebuild makes sense, we'll tell you that too — with a real plan, not a sales pitch.

02

Cloud and Application Depth

From older .NET Framework enterprise apps to modern .NET cloud-ready services, plus AWS and Azure deployments and frontend delivery with HTML, CSS, and JavaScript, we bring practical depth across the full software lifecycle.

03

Low-Risk Engagements

We prioritize stability. Every change is tested, reviewed, and deployed carefully so your production environment stays healthy.

04

Transparent Communication

Plain-language updates, honest timelines, and no technical jargon for jargon's sake. You always know where your project stands.
