First, I fell in love with math. This crush taught me how to concentrate better, work harder, and communicate through symbol language. 📏 🏆 I won several local and international competitions in math and logical problem-solving. 𝐍𝐨𝐰 𝐈 𝐜𝐡𝐨𝐨𝐬𝐞 𝐭𝐨 𝐜𝐨𝐝𝐞. I started learning when I became a student of the Faculty of Management and Information security. With my math background, I quickly broke all barriers and became a Python developer. 🐍 I took the more challenging path than simply taking online courses and stealing someone's code from open repos. 𝐌𝐲 𝐭𝐞𝐜𝐡-𝐬𝐭𝐚𝐜𝐤: 🔷 Django 🔷 Python 🔷 REST 🔷 Git, Sentry, Celery, Pytest, PostgreSQL. 𝐖𝐡𝐞𝐫𝐞 𝐚𝐦 𝐈 𝐬𝐭𝐫𝐨𝐧𝐠𝐞𝐬𝐭? I’ve committed myself entirely to Python so that I can achieve almost anything. I have enough experience to enter an existing project, quickly adapt, and improve my previous work. 📌 Web Application Development; 📌 Website Development; 📌 Back-end development; 📌 Dashboard Development; 📌 Customer Portals Development. I can take a turnkey project, starting with developing documentation, development, tests, and post-project support, and give you a ready MVP/PoC. My colleagues from Regulus work alongside me to ensure every project exceeds client expectations. 🏁 Honestly, my English is so far from ideal. Because when other kids were learning foreign languages, I was gaining a programming background. But we'll hit it off. 𝐖𝐞𝐥𝐥, 𝐈’𝐦 𝐛𝐚𝐬𝐢𝐜 𝐢𝐧 𝐄𝐧𝐠𝐥𝐢𝐬𝐡, 𝐛𝐮𝐭 𝐚 𝐍𝐚𝐭𝐢𝐯𝐞 𝐒𝐩𝐞𝐚𝐤𝐞𝐫 𝐨𝐟 𝐃𝐣𝐚𝐧𝐠𝐨!

Hello! My name is Egor and I'm a full-stack developer with 6 years of experience. My idea is to help people with their web projects. I have developed around 10 successful projects which help my customers to make the world a little bit better. I would be so happy if I can help you with the same goal. As a full stack developer, I can help you with the following things. - Develop from scratch or improve your client web application - Develop from scratch or improve your server application - Write unit or integration tests for your server application. I'm familiar with following technologies. - JavaScript and front-end framework Angular 2+ or library React.js and their ecosystems (such as rxjs or typescript for angular or redux for react) - JavaScript environment for server applications Node.js and framework for it such as Express.js or Fastify - JavaScript frameworks for testing: Karma, Jamine, Jest. Also, I would like to tell you something about my goals. As I think one of the most important things I have done it is to develop PWA. It had helped our users to have better UX and make their life easier because of offline mode. With these technologies we can display content to the user in a browser without the internet connection and also portate our web site to their phones as a native app. As I said before I want to help develop your awesome application!
