I maintain a legacy desktop program written in Pascal and now need it re-imagined as a browser-based application. The goal is to keep every current feature intact while exposing the underlying logic through modern APIs, then presenting it in a clean, responsive web interface. Here’s the workflow I have in mind: • Re-factor or wrap the existing Pascal code so its core routines are callable from HTTP/REST endpoints. • Build the web front-end (framework is flexible; React, Vue, Angular or even a light vanilla stack are all acceptable) that consumes those endpoints and mirrors the original UI/UX. • Package the finished solution with clear deployment scripts and concise technical documentation so it can be dropped onto a standard Linux server. Key points you’ll need to handle: data persistence, session management, and secure API design. If authentication, visualization dashboards, or additional integrations become necessary during the port, we can scope them in once the base application is stable. I will supply the Pascal source, sample data, and a rundown of current workflows. Once the web version reproduces the full behaviour of the desktop tool and passes a brief acceptance test, the project is complete.

Hello, I’m Karthik, a full-stack developer with 10+ years’ experience modernising legacy systems and porting desktop apps to scalable web platforms. I’ve migrated older codebases (including Delphi/Pascal-style logic) into API-driven web apps while preserving business rules. How I’ll approach your port • Analyse Pascal code and isolate core logic • Either wrap via a lightweight service layer or re-implement critical logic in a modern backend (FastAPI/Node) where safer and maintainable • Expose clean REST APIs with proper auth & session handling • Build a responsive web UI (React preferred) mirroring existing workflows • Set up persistence, validation, and secure API patterns Deliverables ✔ Feature-complete web version matching desktop behaviour ✔ Clean, documented code + deployment scripts for Linux ✔ Concise technical docs for future maintenance Tech stack (suggested) Backend: Python FastAPI or Node Frontend: React DB: PostgreSQL/MySQL (as needed) Dockerised deployment for easy setup Timeline Typically 4–8 weeks depending on app size/complexity. I focus on clean architecture, minimal disruption to your logic, and long-term maintainability. Happy to review the Pascal source and propose the best migration path. Ready to start.

Hello I’ve read your project details, and I believe you’re looking for someone who understands both system-level languages and modern web technologies. You want to refactor your Pascal program and expose some of its routines through REST APIs. I can handle this by either: 1. Writing a Node.js or PHP service that interacts with your Pascal routines using PHP FFI capabilities, or 2. Recompiling the Pascal code to WebAssembly (WASM) if it’s a standalone service, allowing it to run directly in a web environment. This way, we can preserve your existing logic while modernizing the application for the web. I hope this approach aligns with your vision. Thanks, Amritpal Singh

Hello, Resonite Technologies here. We have strong experience modernizing legacy applications and turning desktop logic into secure, scalable web platforms. Converting your Pascal system to a browser-based solution while preserving all functionality is exactly the kind of migration work we handle. Our approach • Logic extraction/wrapping: analyze your Pascal code and either expose it via a service layer (e.g., FreePascal/Lazarus + REST) or carefully port core logic to a modern backend where needed. • API layer: secure REST endpoints with proper validation, auth-ready structure, and session handling. • Web UI: responsive front-end (React/Vue) that mirrors your current workflows and UX. • Data & sessions: reliable persistence design and server-side session management. • Security: input validation, access controls, and safe API design from day one. • Deployment: scripts and concise docs for Linux server rollout (Docker optional). Why us • Experience with legacy-to-web migrations. • Clean, well-documented code for long-term maintainability. • Practical focus on feature parity first, then enhancements. Happy to review your Pascal codebase and propose the best wrap vs. port strategy with timeline estimates. Best regards, Resonite Technologies
