I am a Senior C++ / Qt Developer with 8+ years of specialized experience in modernizing legacy 3D desktop applications for Windows. My core expertise lies in rescuing, refactoring, and fully modernizing complex C++ Qt 5 codebases that rely on outdated 3D rendering approaches, turning them into clean, maintainable, high-performance Qt 6 applications ready for today’s fabrication workflows. I have successfully delivered multiple end-to-end legacy rescue projects involving parametric 3D surface generation, imported 3D model data handling, mapping and intersection logic between forms and surfaces, advanced 3D visualization, and geometry/export workflows directly tied to physical fabrication output. I specialize in exactly the type of project described: working legacy Windows desktop applications built in C++ with Qt 5 that use deprecated OpenGL pipelines or custom rendering layers incompatible with modern Qt. I excel at performing deep codebase reviews, identifying reusable core logic (algorithms, parametric generators, intersection engines, export modules), pinpointing what must be rewritten (rendering stack, build system, UI layers), and providing clear recommendations on whether a short legacy diagnostic build step or direct modernization delivers the fastest ROI. My approach has consistently saved clients 40-60% in development time and cost by preserving battle-tested geometry and fabrication logic while upgrading to Qt 6, modern CMake, and current Windows SDKs. Technical strengths directly aligned with your requirements include: • Expert-level C++ (C++17/20/23) combined with deep Qt 5 and Qt 6 mastery, including full migrations from Qt 5 to Qt 6. • Legacy desktop application rescue and modernization — I have rescued 7+ abandoned Qt 5 3D codebases, many of which were shelved due to outdated rendering or production-cost barriers that no longer exist. • 3D rendering, visualization, and geometry-related software: parametric 3D surface generation, mesh import pipelines, boolean operations, surface-to-surface mapping, intersection logic, real-time 3D visualization, and fabrication-ready export workflows (STEP, DXF, STL, G-code, custom CAM formats). • Windows desktop build expertise: clean, reproducible builds with modern tooling, installer creation, and full compatibility with current Windows 10/11 environments. • Proven comfort with fabrication-focused 3D applications — previous projects involved specialized visualization and planning tools for artists and manufacturers moving from prototype to production. In every modernization project I first conduct a thorough codebase audit, produce a detailed report on reusable core logic versus components requiring rewrite, and deliver a practical phased plan with accurate effort estimates. I am highly comfortable with a short, cost-effective legacy diagnostic build step when it accelerates accurate scoping, but I also excel at direct modernization when the client prefers zero time spent on the old environment. All deliverables include full source code, project files (CMake or qmake), detailed build instructions, and comprehensive documentation. Beyond technical delivery, I bring clear spoken and written English, professional communication style, and full availability for periodic voice or video discussions with reasonable overlap during Eastern Time hours (I am based in UTC-5 and keep a flexible schedule to match client needs). I thrive in project-based engagements with defined milestones and fixed-price or milestone-based quoting — exactly as you specified. I never work open-ended hourly arrangements. My track record includes multiple successful Phase-1 assessments that led to full multi-phase modernization contracts for independent artists, small fabrication studios, and specialized manufacturing clients. Clients repeatedly praise my ability to understand both the artistic/creative intent behind parametric 3D tools and the practical engineering demands of modern fabrication workflows. I am meticulous about delivering production-ready, maintainable code that future-proofs your application for the new manufacturing technologies now available. I am immediately available to discuss your legacy 3D desktop application, review the existing codebase, and propose a tailored fixed-price Phase 1 that includes full codebase review, reusable logic identification, modernization roadmap, and clear recommendation on diagnostic build versus direct upgrade. If Phase 1 goes well — as it has with every previous client — I am fully prepared to continue through additional paid phases to deliver the final modern Windows application.

Are you looking for a mix of proficiency, value and fast delivery, here I am! Hi there, my name is Mor Talla SY, an engineer in mechatronics proficient in a lot of things (i mean a lot 😉). Let me break it down for you, you might be interested in one of my skills. ✅ Mechatronics: of course, this is my educational background. I can help my clients in a variety of engineering tasks such as CAD, simulation, stress calculations, academic research and the list goes on. ✅ Video & image editing: with capcut, canva and a bunch of other tools, i can do for you the followings: video editing, video transcription, image editing, advertisement design, and the list goes on. Have a look at my projects... ✅ Excel and VBA: I know how boring and time consuming it can be to process heavy excel sheets. So with my excel skills, i am here to help professionals as well as anyone who wants to be more productive in his daily activities with excel sheets. From simple excel formulas to more complex projects requiring VBA, you are at the right place. ✅ Powerpoint: i don't know if you love visually attractive presentations, but me i do, and i know how to do it also 😉. Powerpoint is a tool a i have been using during my whole engineering curriculum with our various engineering projects and internship presentations. Throughout the years, i have really improved my presentation skills. ✅ Slack, Asana and Front: with there 3 tools, we can do wonders. Asana helps in managing complex projects by allowing us to have an overview of the project, and the interesting part is that we can devide the project into multiple tasks in order to monitor the progress of the project. As for Slack and Front, they are very effective in helping maintain good communication between team members. ✅ English, French and Wolof proficient: these 3 languages are at the heart of my daily activities. I think it is a really valuable skillset combining 3 languages from 3 different continents and 3 different cultures. For the english, i have been communicating with it since childhood (around the age of 7), and, with my electromechanical engineering degree, i have been able to acquire a lot of technical terms, which is pretty useful for technical projects. As for the french, i can say that it is a mother tongue to me. Actually, i have been speaking french all my life since i am from a french speaking country. Plus, i have done my engineering degree in France, so this helped me learn the french culture and definitely adopt their accent. As for Wolof, this is my mother tongue, so no need to be clearer 😊. I think my profile is pretty interesting, don't you? It combines technical skills with soft ones, which is something required for the success of every project. Oh, if you really made it through this long presentation, I truly appreciate it. Thank you so much. Feel free to contact me to see how we can work together. Best regards.
