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. ít hơn
