Ihor (Harry) ChyshkalaAs an experienced Full Stack Software Developer with over 5 years of professional experience, I specialize in building modern, scalable web applications using cutting-edge technologies. My expertise spans the entire development lifecycle, from initial architecture design and database modeling to frontend implementation, API development, and cloud deployment. I'm passionate about creating high-performance solutions that not only meet technical requirements but also deliver exceptional user experiences and drive measurable business results.
My technical foundation is built on React, Next.js, TypeScript, and Node.js – a powerful combination that enables me to build everything from simple landing pages to complex enterprise applications. I believe in writing clean, maintainable code that follows industry best practices and design patterns. Every project I work on benefits from my commitment to code quality, comprehensive testing, and thorough documentation, ensuring long-term maintainability and scalability.
On the frontend, I excel at creating responsive, accessible user interfaces using React.js and Next.js 16. I leverage the latest features like Server Components, Server Actions, and the App Router to build blazing-fast applications with optimal SEO performance. My styling approach combines Tailwind CSS for utility-first development with modern CSS techniques for custom animations and responsive layouts. I'm well-versed in state management solutions including Zustand, Redux, and React Context, choosing the right tool for each project's specific needs.
For backend development, I build robust APIs using Node.js with Express or Next.js API Routes, implementing RESTful architectures and GraphQL when appropriate. I have extensive experience with database design and optimization, working with both SQL databases (PostgreSQL, MySQL) and NoSQL solutions (MongoDB, Redis). My backend code emphasizes security best practices, including proper authentication and authorization, data validation, and protection against common vulnerabilities like SQL injection and XSS attacks.
I'm a strong advocate for TypeScript in all my projects, as it significantly improves code quality, reduces bugs, and enhances developer experience through better IDE support and autocompletion. My development workflow includes comprehensive testing strategies using Jest, React Testing Library, and Playwright for end-to-end testing. I implement CI/CD pipelines with GitHub Actions or GitLab CI, ensuring every deployment is tested and reliable.
Version control is fundamental to my workflow – I use Git extensively with clear commit messages, feature branches, and pull request workflows. I'm comfortable working in both solo and team environments, adapting my workflow to match team conventions while advocating for best practices. Code reviews are an essential part of my development process, both giving and receiving feedback to maintain high code quality standards.
My experience with cloud platforms includes AWS (EC2, S3, Lambda, RDS), Vercel, DigitalOcean, and Heroku. I implement infrastructure as code using tools like Terraform and configure containerized applications with Docker and Docker Compose. For production deployments, I set up monitoring with tools like Sentry for error tracking, implement logging solutions, and configure analytics to track application performance and user behavior.
Performance optimization is a key focus in all my projects. I implement lazy loading, code splitting, and optimize bundle sizes to ensure fast load times. Database queries are carefully optimized with proper indexing, and I use caching strategies (Redis, CDN) to minimize server load and improve response times. My applications are built with scalability in mind, ready to handle growing user bases and increasing data volumes.
Throughout my career, I've delivered successful projects across diverse industries including e-commerce, fintech, healthcare, and SaaS. I've built custom e-commerce platforms with advanced features like inventory management, payment processing integration (Stripe, PayPal), and personalized recommendation engines. In fintech, I've developed secure transaction systems and financial dashboards with real-time data visualization. My healthcare projects have included HIPAA-compliant patient management systems and telemedicine platforms with video integration.
I excel at transforming business requirements into technical solutions. My process begins with thorough requirement gathering and system design, followed by iterative development with regular stakeholder communication. I provide realistic estimates, maintain transparent project timelines, and deliver working software incrementally. Whether working on a startup MVP that needs rapid development or an enterprise system requiring careful planning and documentation, I adapt my approach to match project needs.
The web development landscape evolves rapidly, and I'm committed to continuous learning. I regularly explore new technologies, contribute to open-source projects, and stay updated with the latest industry trends. My technical blog serves as both a learning platform and a way to share knowledge with the developer community, covering topics from advanced React patterns to database optimization techniques and cloud architecture best practices.
I'm particularly interested in emerging technologies like AI integration in web applications, WebAssembly for performance-critical features, and progressive web apps (PWAs) for mobile-first experiences. I experiment with these technologies in side projects before incorporating them into production applications, ensuring I can leverage new capabilities while maintaining stability and reliability.
When you work with me, you get more than just code – you get a dedicated partner invested in your project's success. I bring strong problem-solving skills, attention to detail, and a user-centric mindset to every project. Communication is a priority; I provide regular updates, am responsive to feedback, and proactively identify potential issues before they become problems. My goal is to deliver solutions that not only meet immediate requirements but are positioned for long-term success and growth.
