A formally-educated software engineer with quite a few skills under my sleeve. My repertoire includes several Python niches such as Web back-end deveploment with Django and data science/machine learning model creation with pandas, sklearn and numpy. I also make video games with Unity3d + C# and have a strong sense of game design and balancing that I owe to being a seasoned gamer myself. For examples of past work, please check my portfolio section and past upwork projects. I speak Arabic (Natively), English and French. I have perfect command of every dimension of language mastery in all three of them. My spoken English accent is mostly American-like. What I do: ✅ Unity 3D development with C#, whether for games, VR/AR apps, or anything that could be made using the technology. ✅ Game design and level design (Though not graphic design, sadly). ✅ Backend development in Python + Django. ✅ Machine Learning tasks in Python + sklearn/pandas. ✅ General Python scripting. ✅ Competitive programming tasks or Algorithm and Data Structures tasks in C, C#, Java, and of course, Python. ✅Flutter mobile apps. ✅ Teaching most topics related to an academic CS curriculum (Python, C and Java programming, Algorithms, OOP, Design Patterns, Databases, ...etc.). ✅ Anything that requires knowledge about Pokémon video games (Yes there are people who pay for that). I do also possess a feeling for human words, for the way I speak to machines with my lines of code complements how I can speak to flesh-and-blood people in the realms of public speaking, poetry, creative writing, technical writing, social media content, and translation. By means of either implementation or verbalization, I give life to ideas and concepts. I can do the following using my linguistic abilities: ✅ Translation between Arabic, French and English ✅ Writing in the three aforementioned languages, technical or otherwise. ✅ Poetry and songwriting.

Senior Full Stack / Serverless Engineer specializing in migrating from legacy code, working in polyglot (multi-language) environments, and protecting data integrity. I build modular, testable, and scalable systems that guarantee the integrity of your data, ensuring it can keep up with all your business needs. I have driven the migration of large-scale enterprise applications from legacy implementations to modern, cloud-based architectures while ensuring no loss of data in flight and minimizing downtime. As business needs change, technologies evolve, and developers leave a team, you must get to a robust, easy-to-maintain, well-documented codebase. Without institutional knowledge of the history behind each design decision, you can wonder how to escape a chaotic situation without affecting your end users. I bring a systematic approach to navigating these kinds of projects. Whether this is where your system is now, or you're starting something new and want to ensure you keep up with best practices from the start, working with me will ensure you end up with maintainable, thoroughly tested, clearly documented, and stable code. I will start by getting to know your business needs and technical requirements and, from there, develop a plan that divides your goals into clearly defined short-term milestones. My fixed-priced contracts ensure that your budget is not affected by surprises. At the same time, my agile approach to planning will keep things flexible enough to accommodate any shifting priorities.Scheme
