Operational Impact: FireForge is an AutoCAD workflow assistant for fire protection engineers. It automates the repetitive process of isolating architectural layers, copying each into a spaced review group with a common registration marker, and opening a clean workspace — without modifying the original deliverable.

• Platform: AutoCAD (2015–2027) on Windows — .NET Framework 4.8, .NET 8, and .NET 10 targets.
• Safe Mode (default): creates a separate output DWG with separated layer groups; source drawing never modified.
• Preflight scan: entity counts per layer, file size, risk level, and warnings for xrefs, proxy objects, and heavy geometry.
• Registration marker (FF_LAYER_REFERENCE) replaces manual Layer 0 circle — inserted in every copied group for visual alignment.
• Transparent UI: docked PaletteSet with Process, Settings, Results, and About tabs plus ribbon integration.

Built With: C#, WPF, MVVM, AutoCAD .NET API, .NET 8, .NET Framework 4.8, .NET 10

Operational Impact: Datuma (datuma_mobile) is a production Flutter app for iOS and Android that puts survey point management in the field. Provider + Repository architecture over SQLite (schema v12), isolate-based parsers ported from the Survey Point Manager C# plugin, proj4dart coordinate conversion (WGS84/UTM/State Plane), and Google Maps with shape drawing and advanced measurement. Optional Supabase community, Google Drive backup, and Firebase Crashlytics — core import/export/projects work fully offline without an account.

• 12+ import parsers and exporters (CSV, GSI, SDR, IDX, DXF, KML, GeoJSON, LandXML, Shapefile, LAS, SPJ) with content-based auto-detection and compute() isolate offload.
• Five-field point model (PN/E/N/Z/Code) aligned with Survey Point Manager AutoCAD plugin — CoordinateService and TXT/IDX parsers ported from C# plugin sources.
• GoRouter StatefulShellRoute with 4-tab shell (Home, Projects, Learn, Tools); map stack split into MapProvider, MapStateManager, MapRenderingService, MapGeometryEngine.
• Versioned .spj project package (datuma.project.package v2) for cross-device sharing; quick-convert workflow with conversion_history table.

Built With: Flutter 3.38+, Dart 3.10, Provider, GoRouter, SQLite (sqflite), Google Maps, proj4dart, Supabase, Firebase Crashlytics

Core Technical Takeaway: Insulate complex data constraints within the database database schema rather than delegating them entire to fragile application code.

Architecture: High-performance PostgreSQL systems use Partial Indexes to ignore nulls, preventing massive bloated indices, combined with CHECK constraints that enforce complex statuses at the database engine level.

Implementation: A common mistake in large databases is querying timestamp statuses by default table scans, causing full disk seeks. Building targeted indices containing exact Boolean flags addresses this bottleneck.

Core Technical Takeaway: Always treat COM interop resources as fragile, explicit memory containers that must be disposed of before application execution terminates.

Architecture: Developing automation for desktop CAD demands absolute synchronization between C# managed structures and the native AutoCAD engine. Transactions ensure if drawing creation crashes midway, the viewport rolls back entirely.

Implementation: To safely interact with native geometry APIs, developers must lock document structures, write safely within boundaries, and execute targeted disposals to prevent software lockups.

Core Technical Takeaway: Bridge backend ecosystems via binary communication layers like gRPC or message queues to completely bypass slow HTTP parsers.

Architecture: High-throughput enterprise API setups route user requests into an ultra-fast .NET engine which processes credentials and schemas, before throwing raw mathematical matrixes directly into optimized Python processes over gRPC.

Implementation: Routing data packets across C# and Python requires shared contract layouts (Protobuf) and robust error middleware to catch timeouts on either assembly during live runs.

Operational Impact: A web platform built for surveying professionals who need quick field math and trustworthy format conversion without uploading coordinate files. Six calculators work instantly with no account. Three converters handle GSI, CSV, and DXF entirely in your browser, with Learn articles and reference guides tied to each tool.

• Six public calculators — bearing/distance, traverse closure, Bowditch adjustment, Tienstra resection, column center, and polygon area — usable on phone or laptop with no sign-in.
• GSI ↔ CSV and CSV → DXF converters process files on your device; only file size and point count are sent to check credits, never the coordinates themselves.
• Fair credit billing: 30 free conversions per month, charged only after a successful download, with a five-minute window to re-export the same job to another format at no extra cost.
• Learn articles and GSI format reference paired to every calculator and converter — read the method, then run the tool on the same site.
