IMPORTANT INFO !!** Paul L. @paul612 who left last comment is a scammer. He wanted me to test his .apks but he couldn't even build them properly and they didn't boot up at all! And then he wanted me to develop for him for free. Don't be like @paul612, be honest and I will be honest **** I have done a lot of projects connected with virtual reality, Oculus Rift, Oculus Quest / GO and HTC Vive (I developed unique calibrating system for making free roaming VR Arena). Also I have a some knowledge about design, drawing, 3D modeling, and sound engineering because for some years I have been making games utterly alone. I am not afraid of any kind of challenge. === If you do not speak English we can try to communicate via translators I am sure that we will manage to do it :) less

    ✅ 15+ years of experience ✅ 70+ projects delivered ✅ 10k+ Hours ✅ 100% Success Score ✅ 5 Stars ✅ Backed by a skilled team for handling complex projects Doubtful about finding a developer who can handle complex challenges or pick up the pieces from a previous failure? Wondering if it's possible to have a bug-free, scalable solution? I've seen and solved it all. With a commitment to deliver and a track record of success, I am here to protect your project from common setbacks and elevate it to its highest potential. Hi! I'm a Senior Full-stack developer with over a decade of experience in the tech industry. I specialize in delivering comprehensive frontend and backend solutions, from concept to deployment, bolstered by solid experience as a Solution Architect and a Dev Lead. In 2015, I gathered my own web dev team from the ground up, as an extension of my software developer expertise and wisdom. Now, with over70 successful projects behind us, we focus on creating IT solutions for businesses to guarantee their growth and prosperity. ---=== Why I Stand Out: ===--- - Unmatched Reliability: Every project I undertake is guaranteed to reach completion, irrespective of the initial condition or challenges encountered along the way. - Continuous Support: My relationship with clients extends beyond project completion. I offer ongoing support to ensure continued success and adaptability in an ever-evolving digital landscape. - Scalable Team Leadership: While I thrive as a sole developer, I also lead a talented team of developers, ready to scale according to your project needs. This flexibility allows me to tackle projects of any size and complexity, delivering high-quality solutions on time and within budget. - End-to-End Solutions: From initial consultation to final delivery, I manage all phases of the development cycle. ---=== My Technical Foundation: ===--- - Frontend Expertise: Proficient in HTML, CSS, JavaScript, TypeScript, and an array of frameworks & libraries including React.js (with Redux, Thunk, Sagas, Next.js), Bootstrap, Material UI, CSS in JS, Tailwind, and React-Admin. - Backend Proficiency: Skilled in Node.js, Express.js; along with Feathers.js, RESTful API, GraphQL development, Socket.IO, Strapi, and BullMQ. - Data Visualization Mastery: Experienced with D3.js, Chart.js, GSAP, Three.js, React Three Fiber, and techniques involving Canvas and SVG. - Database Management: Competent in managing data using SQL, PostgreSQL, MongoDB, and ElasticSearch. -DevOps & Deployment: Knowledgeable in Docker, Kubernetes, and implementing CI/CD pipelines with GitHub, GitLab. less
