    Hello, I'm Bilal, a full stack developer and designer Expert. I've been freelancing for several years now, working my way up to Top Rated status. Started with PHP and WordPress sites, learned React when clients needed modern interfaces, picked up Python for AI projects, and along the way realized many clients need design too. So I learned Figma, logo design, and UI/UX basics. Most of my work falls into a few categories: fixing WordPress sites, building React applications, creating APIs with PHP or Python, designing interfaces in Figma, and lately, adding AI features like chatbots. Sometimes I'm designing a logo in the morning and integrating OpenAI in the afternoon. Variety keeps it interesting. I handle complete projects - from initial Figma mockups to deployed applications with SEO optimization. It saves clients from hiring multiple freelancers. Need a logo? I'll design it. Want to see the website design first? I'll create Figma prototypes. Ready to build? I'll code it in React or PHP. Need it to rank on Google? I'll handle the SEO. My toolkit includes PHP, Laravel, WordPress, React, Python, Node.js, Figma for designs, Adobe tools for logos, and AI integration with OpenAI. Not claiming to be the world's best at everything, but I'm solid at all of them and that combination is useful for most projects. The Preferred Freelancer badge came from delivering consistent work and maintaining good client relationships. I respond quickly, explain technical stuff in normal language, and if something's outside my scope, I'll tell you honestly. Whether you need a logo, a Figma prototype, a WordPress fix, or a full AI-powered web application, let's talk about what you're trying to build. Available for both hourly and fixed-price work. menos

    Hey there! I’m a full stack developer with over 10 years of experience building all kinds of digital products—from websites and mobile apps to blockchain platforms, embedded systems, and AI-powered solutions. I’ve worn a lot of hats over the years, but the common thread has always been solving real problems with smart, reliable tech. Whether you’re looking to launch something new or need help improving what you’ve already built, I’m here to jump in and make it work. -Web & Mobile Apps: Clean, responsive designs and solid backend logic. I work with tools like React, Vue, Node.js, Django, Flutter, and more to build apps people actually enjoy using. -Embedded Systems & IoT: I build smart, connected hardware using platforms like Arduino, ESP32, and Raspberry Pi. From prototyping to production-ready firmware, I work with C/C++, MicroPython, and platform-specific SDKs to control sensors, motors, displays, and more. I also integrate these systems with web and cloud services—often adding AI for tasks like real-time data analysis, voice interaction, or image recognition at the edge. -AI & Machine Learning: I integrate tools like GPT-4, Whisper (speech-to-text), and DALL·E into web and mobile platforms—automating workflows, building chatbots, content generators, or even custom AI copilots for your users or team. I also work with Python-based ML frameworks like TensorFlow and PyTorch for custom models and training. -Blockchain & Smart Contracts: I’ve developed and audited smart contracts (mainly Solidity) and built dApps that connect seamlessly with Ethereum, Solana, and BNB networks. Let’s bring your vision to life with clean architecture, scalable code, and tech that lasts. I’m ready to contribute as your long-term tech partner or on-demand expert. menos
