Technical Capabilities

Core Development and Migration Services

Custom .NET Software Development

PCG develops production software on C# .NET Core 8, ASP.NET Core, Razor Pages, and SQL Server for organizations whose operational requirements exceed the capabilities of available commercial products. Completed systems have included fleet management platforms, physician credentialing and payroll systems, compliance tracking applications, and public safety dispatch software. Full source code ownership transfers to the client at project completion.

Environmental and Industrial Compliance Software

Compliance software has represented approximately one-third of PCG's three-decade project volume: waste manifests, air permits, EPA Title V, remediation documentation, and OSHA record keeping. FireFlight Data System is a modular platform developed and maintained exclusively by PCG for environmental compliance and industrial operations, delivering that same depth of domain experience in a fully hosted, directly supported system.
LEARN MORE
Legacy System Migration and Application Rescue

PCG migrates Access databases, VB6 applications, FoxPro systems, legacy ASP applications, and Excel-based operational systems to current .NET Core 8 architecture. Business logic, data integrity, and process workflows are preserved through the migration. Existing documentation is not a prerequisite for initiating an engagement. PCG performs technical reconstruction where source documentation is absent.

Common Engagement Scenarios

Technical Situations That Typically Precede an Engagement With Us

A production system has no surviving documentation and the original developer is no longer available.

We have performed technical reconstruction and migration on production systems accumulated over 10 to 20 years of development, in cases where no documentation, design specifications, or original developer access existed. The completeness of documentation at project initiation does not determine whether a successful migration is achievable.

A Microsoft Access database is generating errors that internal staff cannot resolve.

We have maintained and migrated Microsoft Access systems across all versions of the platform since its initial release. Data corruption, version incompatibility, 32-bit architectural constraints under Windows 10 and 11, and performance degradation under scaled data volume are recurring issues with established resolution paths at PCG.

Compliance requirements are specific enough that no available commercial EHS platform provides an adequate fit.

Environmental consulting firms, industrial EHS departments, and field inspection organizations operating under agency-specific regulatory frameworks frequently encounter this gap. We have built compliance software across all three contexts: FireFlight Data System provides natural language query capability against live operational and compliance data.

A critical operational process is managed within a spreadsheet that represents an institutional single point of failure.

When the individual with working knowledge of a complex operational spreadsheet departs, the organization loses both the tool’s functionality and the institutional knowledge embedded in its logic. We convert these systems to documented, maintainable applications before that dependency becomes an operational crisis.

FAQ

Technical and Commercial Questions Addressed Before Engagement

PCG FAQ Block
Yes. We have maintained and migrated Microsoft Access systems across all versions of the platform since its original release, completing hundreds of migrations to SQL Server, cloud-hosted environments, and modern .NET applications. Access to the original developer is not a requirement for initiating an engagement. The majority of these projects complete within 4 to 12 weeks, with duration determined primarily by the volume of undocumented schema changes accumulated over the system's operational history.
Three technical paths are available. A compatibility shim can defer failure but does not address the underlying architectural incompatibility. A targeted rewrite of the components generating failures is appropriate when the failures are isolated to specific modules. Full migration to .NET Core 8 is the permanent resolution and the approach we recommend for any application that is operationally critical. We have executed all three approaches, with the appropriate path determined by system scope, organizational timeline, and operational risk tolerance.
We initiate a technical reconstruction phase before any migration activity begins. This involves systematic analysis of the existing database schema, codebase, and runtime behavior to produce a documented map of the system's data structures, business logic, and operational dependencies. This phase typically adds one to three weeks to the overall project timeline. We do not proceed to migration without it, because migrating from an incompletely understood system is the primary cause of data loss and business logic failure in legacy migration projects.
FireFlight provides a pre-built platform layer that we configure to meet a client's specific workflow requirements, reducing time-to-production compared to building the platform layer from scratch. A fully custom development engagement is appropriate when the business logic and workflow requirements are complex or specialized enough that no existing platform architecture provides a suitable foundation. We determine the appropriate path during the diagnostic phase.
We have delivered production systems for Fortune 500 organizations including ExxonMobil, as well as for owner-operated environmental consulting firms with fewer than 20 employees. Organizational size is not the primary qualifying criterion. The determining factors are whether the technical requirement falls within our documented scope, whether the project timeline is realistic, and whether a single decision-maker or small team has authority to initiate an engagement.
We maintain all systems we build under a monthly retainer structure covering hosting on our infrastructure, ongoing platform maintenance, direct engineering support via telephone, authorized minor system modifications, and platform updates. Technical issues are typically resolved within hours of the initial contact, because the engineer receiving the call has direct working knowledge of the system's architecture. There is no intermediary support tier and no escalation requirement.
