CodeJump takes on the hard parts: aging applications that still run the business, databases that feed dozens of downstream systems, and engineering tools nobody else can maintain. We modernize them carefully, document everything, and leave you with software your team understands.
Services
Senior engineering across the whole lifecycle, from the first look at a legacy codebase to a production rollout on a modern stack.
We migrate VB6, classic ASP.NET Web Forms and .NET Framework applications to .NET 8+ and Blazor. Business rules and calculations are preserved line by line and verified against the original before anything is retired.
We design and tune SQL Server platforms that move data reliably at scale: ETL orchestration, snapshot distribution, index maintenance, and schema version control with Flyway and Redgate.
We build web applications that fit how your business actually works, including operations portals, booking and reservation systems, online auctions, and real-time dashboards.
We audit and harden applications that handle regulated or sensitive data. That covers credential handling, Active Directory and LDAP integration, PHI access controls, and readiness work for frameworks such as CMMC.
We port and extend technical software for laboratories and engineering teams. Analysis engines, test-equipment data formats and charting are rebuilt with the math intact and the results traceable.
Before we write code, we write down what the system actually does. You get architecture docs, business-rule inventories, runbooks and user guides that outlast any single developer.
Selected Work
Clients are kept confidential. These summaries describe the kind of work we do and the results we aim for.
Healthcare · Data Platform
We built operations and subscription-management portals for a SQL Server platform that distributes Epic Clarity data to more than 70 subscriber databases across a multi-server estate. The portals provide monitoring across servers with fault isolation, PHI-restriction safeguards, and full schema control under Flyway.
.NET 8 · Blazor · Dapper · SQL Server AlwaysOn · Flyway
Engineering · Modernization
We ported a full electromagnetic-compatibility analysis application, covering radiated and conducted emissions, crosstalk and susceptibility models, from VB6 to Blazor Server. Every calculation was carried over faithfully, and the new version adds interactive charts, printable reports and SQL Server persistence.
C# · Blazor Server · Chart.js · Dapper
Laboratory · Security
We replaced a Web Forms client/employee file-exchange portal with a modern Blazor application. The rewrite moved passwords from legacy encryption to modern hashing, added Microsoft Graph and Active Directory sync, and introduced templated notifications. It was part of a broader CMMC readiness effort.
.NET 9 · Blazor · Microsoft Graph · Entra ID
Tourism · Small Business
Modernizing a 100+ page reservation system for a guided-tour operator. The work covers seat-capacity rules, agent commissions, online payments and regulatory reporting. We documented everything first, then rebuilt on a clean domain model.
.NET 8 · Blazor · MudBlazor · ASP.NET Identity
E-commerce
Ongoing development and hosting support for a specialty online auction, including bidding and closing rules, automated notifications, and production operations on a managed VPS behind Cloudflare.
ASP.NET · SQL Server · SendGrid · Cloudflare
Fintech · Product
We took a single-file prototype and turned it into a full-stack application with live market data, a configurable rule engine, candlestick charts with signal markers, and push notifications over SignalR.
ASP.NET Core · SignalR · Next.js · TypeScript
Approach
Modernization fails when teams guess at what the old system does. Our process is built so that doesn't happen.
We read the code, the schema and the stored procedures. We inventory every page, report and business rule, and record open questions instead of making assumptions.
You get architecture notes, a migration plan and a business-rule catalog. You review and approve the plan before any production code is written.
We deliver in clean, phased increments that build without warnings. Read-only phases come first where risk is high, and quirks in the original behavior are preserved deliberately and marked.
We run old and new side by side and compare outputs. Then we deliver runbooks, a developer guide and a user guide so your team owns the result.
Technology
We know the modern Microsoft stack well, and we're fluent in the older technology it replaces.
Why CodeJump
Many firms quote a rewrite without opening the legacy code. We start with it. That's how we find the capacity rule hidden in a SQL function, the time-zone hack that shifts every timestamp, and the hard-coded key that should have been rotated years ago, before they turn into production incidents.
Tell us what you're running, what's worrying you, and where you want to be. We'll reply with an honest assessment of the next step, even if the answer is "leave it alone."
