Looking to hire a full-stack developer for your next project? I'm Ihor (Harry) Chyshkala, an experienced software engineer and CTO available for freelance projects, consulting engagements, and full-time opportunities. Based in Manchester, UK, I work with clients globally to deliver high-quality web applications, optimize existing systems, and provide technical leadership for growing teams. Whether you need a complete application built from scratch, require expertise for a specific technical challenge, or want strategic guidance on technology decisions, I'm here to help.

With over 18 years of experience spanning software development, technical leadership, and fintech innovation, I bring a unique combination of deep technical expertise and business understanding to every engagement. I don't just write code – I partner with clients to understand their business goals, identify the right technical approaches, and deliver solutions that drive measurable results. My track record includes projects that have reduced infrastructure costs by 45%, improved application performance by 70%, and increased conversion rates by 23% through strategic technical improvements.

Services Offered

Full-Stack Web Development: I build complete web applications using modern technologies like React, Next.js, TypeScript, and Node.js. From simple landing pages to complex SaaS platforms, I deliver production-ready code that's maintainable, scalable, and optimized for performance. My development process includes comprehensive testing, thorough documentation, and deployment setup to ensure your application is ready for real users from day one.

Frontend Development: Specializing in React and Next.js 16, I create responsive, accessible user interfaces that work flawlessly across devices. I leverage the latest Next.js features like Server Components and Server Actions for optimal performance and SEO. Whether you need a complete frontend built, a legacy codebase modernized, or specific features implemented, I deliver clean, efficient code following industry best practices.

Backend & API Development: I architect and implement robust backend systems using Node.js, Express, or Next.js API Routes. This includes RESTful API design, GraphQL implementations, database design and optimization for both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB) systems, authentication and authorization systems, and third-party API integrations. Security is always a priority – your data and users are protected through best practices and proven patterns.

Fintech Development: With extensive experience in financial systems from my banking background, I'm uniquely qualified for fintech projects. I've integrated payment processors like Stripe and PayPal, built transaction systems handling thousands of payments, implemented financial dashboards with real-time data, and ensured compliance with financial regulations. If your project involves payments, financial data, or regulatory requirements, you'll benefit from my specialized expertise.

Technical Consulting & Architecture: Sometimes you don't need someone to write code – you need strategic technical guidance. I provide consulting services including technology stack recommendations, system architecture design, code and architecture reviews, performance optimization strategies, and technical due diligence for acquisitions. My business-focused approach ensures recommendations align with your goals and constraints.

DevOps & Cloud Infrastructure: I set up and optimize cloud infrastructure on AWS, Vercel, DigitalOcean, and other platforms. Services include CI/CD pipeline implementation, Docker containerization, database setup and optimization, monitoring and error tracking configuration, and cost optimization to reduce cloud spending while maintaining performance. Many clients have saved thousands monthly through strategic infrastructure improvements.

Why Work With Me

Business-Focused Development: My background in sales and marketing gives me a unique perspective on how technology drives business results. I don't just implement features – I ask questions about business goals, suggest alternatives that might better serve your objectives, and measure success by business metrics like revenue, conversion rates, and cost reduction. Every technical decision is made with your business success in mind.

Clear Communication: One of the biggest challenges in working with developers is communication. I pride myself on explaining technical concepts clearly to non-technical stakeholders, providing regular progress updates without being asked, being honest about challenges and realistic with timelines, and being responsive to questions and feedback. You'll always know where your project stands and what to expect next.

Quality & Reliability: When you hire me, you get professional-grade work. This means comprehensive testing to catch bugs before they reach users, clean, documented code that other developers can understand and maintain, adherence to security best practices to protect your business and users, performance optimization for fast, responsive applications, and proper error handling and logging for easy troubleshooting. I take pride in delivering work that exceeds expectations.

Flexible Engagement Models: I understand that different projects have different needs. I'm available for short-term projects (4-6 weeks for focused deliverables), medium-term contracts (3-6 months for substantial applications), ongoing retainers (monthly hours for continuous development and support), hourly consulting (for specific questions or reviews), and full-time positions (for the right opportunity). We can discuss what arrangement works best for your situation.

Typical Project Process

My development process is designed to deliver value quickly while maintaining quality. We start with a discovery phase where I learn about your business, users, and goals, understand technical requirements and constraints, discuss timeline and budget considerations, and establish clear success criteria. This upfront investment in understanding prevents costly misunderstandings later.

Next comes planning and design where I create technical specifications and architecture documents, design database schemas and API contracts, plan development phases and milestones, and set up project management and communication channels. You'll receive detailed documentation showing exactly what will be built before significant development begins.

During development, I work in iterative sprints (typically 1-2 weeks), provide regular demos of working features, communicate proactively about progress and any blockers, and remain flexible to accommodate changing requirements. You'll see progress continuously rather than waiting until the end for a big reveal.

Testing and quality assurance happens throughout development, not just at the end. This includes comprehensive unit and integration testing, manual testing across devices and browsers, performance testing and optimization, security review and vulnerability scanning, and code review (by me or your team if applicable). Quality is built in, not bolted on.

Finally, deployment and handoff ensures you can run and maintain the application. I handle production deployment and configuration, provide thorough documentation for running and maintaining the application, offer training for your team if needed, establish monitoring and error tracking, and provide post-launch support to address any issues. You're never left stranded after launch.

Industries & Experience

I've successfully delivered projects across diverse industries: E-commerce platforms with payment processing, inventory management, and personalized recommendations; Fintech applications handling transactions, financial data, and regulatory compliance; Healthcare systems requiring HIPAA compliance and secure patient data handling; SaaS products with subscription management, team collaboration, and admin dashboards; Media & Publishing platforms with content management and user engagement features; and Education platforms with course management and student tracking.

This diverse experience means I can quickly understand your industry context, anticipate common challenges in your domain, apply proven patterns from similar projects, and avoid pitfalls that catch less experienced developers. While every project is unique, my broad experience provides a strong foundation for whatever challenges arise.

Remote Work & Availability

Based in Manchester, UK, I work in the GMT timezone (UTC+0) and am available Monday through Friday, 9:00 AM to 6:00 PM GMT, with flexibility for client meetings outside these hours when needed. I'm experienced with remote collaboration using tools like Slack, Discord, or Microsoft Teams for communication; Zoom or Google Meet for video calls; GitHub, GitLab, or Bitbucket for code; Jira, Linear, or Trello for project management; and Figma or similar tools for design collaboration.

I've worked successfully with clients across Europe, North America, Asia, and Australia, adapting my schedule when necessary to ensure good overlap for communication. Remote work is not a limitation – with the right processes and tools, it's often more efficient than co-located work.
