I am a PHP developer with experience in creating web applications for industries like logistics, proptech, healthtech, e-commerce, finance, and SaaS. I develop solutions that align with business objectives, focusing on enhancing operational efficiency and user experience. I specialize in PHP development using frameworks like Laravel and Symfony. My expertise covers custom PHP solutions tailored to specific business needs, supporting full-cycle web development from database architecture to application deployment. I prioritize clean code, maintainable architecture, and scalability in every project. Key areas of expertise: • PHP development using Laravel and Symfony • Custom PHP solutions for diverse business applications • Web development with HTML, CSS, JavaScript, and jQuery • Database management with MySQL and PostgreSQL • API development and integration with RESTful APIs • Full-cycle web application development • Version control with GitHub PHP is at the core of my development approach. I leverage Laravel for rapid development to create secure, scalable applications. Symfony allows me to build complex, enterprise-level systems with its reusable components, service-oriented architecture, and strong emphasis on performance optimization. For database management, I work extensively with MySQL and PostgreSQL. I design relational databases optimized for data integrity, performance, and scalability. My experience includes handling large datasets, complex queries, and ensuring seamless data flow within applications. Query optimization, indexing strategies, and normalization techniques are integral to my database management approach. I develop APIs based on RESTful principles, enabling seamless integration with third-party services and internal systems. My work includes creating custom APIs for web and mobile applications, ensuring secure data communication across platforms. I focus on API security, efficient data handling, and robust error management to support business-critical integrations. In front-end development, I utilize HTML, HTML5, CSS, and JavaScript to build responsive and intuitive user interfaces. I also incorporate jQuery to enhance interactivity, providing dynamic features that improve user engagement. I use GitHub to manage code changes, facilitate team collaboration, and streamline deployment processes. Version control practices help maintain code integrity, support agile development, and ensure efficient project management through branching strategies and continuous integration workflows. Using Laravel, I build secure and scalable applications with rapid development capabilities, leveraging its robust ecosystem, middleware support, and testing tools to deliver maintainable codebases. Symfony's flexibility allows me to create modular, high-performance applications tailored to complex business requirements, utilizing its dependency injection container and event dispatcher components. My approach to database design includes creating normalized structures for efficient data storage and retrieval. I use MySQL for applications requiring transactional consistency and PostgreSQL for analytical workloads that demand complex queries and large data handling. I implement advanced SQL techniques, such as stored procedures, views, and triggers, to enhance database functionality and performance. API development is crucial for modern web applications. I design and implement RESTful APIs that enable seamless integration with mobile apps, third-party services, and cloud platforms. My API solutions are secure, scalable, and designed for efficient data exchange, supporting real-time functionality when needed. I ensure compliance with API standards, such as OpenAPI specifications, to maintain consistency and reliability. In front-end development, I focus on creating user-friendly interfaces with clean layouts and responsive design principles. I use HTML and CSS for structure and styling, while JavaScript and jQuery add interactive elements that enhance the user experience. My goal is to deliver visually appealing and functional applications that work seamlessly across devices, optimizing for both performance and accessibility. Version control with GitHub supports my collaborative development process. I manage code repositories, track changes, and implement branching strategies to ensure smooth workflows in both solo and team environments. This approach reduces development risks and maintains code quality throughout the project lifecycle, enabling efficient code reviews, issue tracking, and continuous deployment. My development process is driven by best practices and portfolio includes a variety of web applications tailored to different business needs, utilizing PHP, Laravel, Symfony, MySQL, PostgreSQL, and RESTful APIs. Let's discuss how I can contribute to your project and deliver PHP solutions that align with your business goals. Feel free to reach out to start the conversation.Web Application

Hello, I am a back-end developer at Regulus Team. My stack is Python/Django. I have experience in different fields of studies. My Ph.D. degree is in computational chemistry. In my work, I dealt with theoretical chemistry, namely the applying of statistical and machine learning methods in chemistry and quantum chemistry. As the result I wrote multiple programs to carry out my research studies; first, in Fortran and after in Python3. As a rule, due to the high computational capacity of programs, their calculation was carried out on Ubuntu servers (in the administration of which I participated directly). - I have knowledge of Django, Django REST framework, PyTest, and git. - I have worked with the following Python packages: Numpy, NeuPy, Scikit-Learn, Rdkit, Chemoffice, I have basic knowledge of Keras. - I have basic knowledge of unit-testing packages, JavaScript I love learning new technologies and improving knowledge constantly.
