How we develop web products

Here are the steps we go through together:

1. Discovery: Laying the groundwork

At first, we sit down together to deeply understand your vision, users, and goals. Our BAs map clear user journeys and define web development strategy. Next, we create clickable wireframes and interactive prototypes to visualize your future web application. Then, we prepare predictable and structured estimates and a timeline, proactively spotting risks and outlining mitigation plans β€” ensuring clarity, zero surprises, and a smooth web development process from start to finish.

2. Design: Crafting user-centric interfaces

Great web development should lead to seamless experiences on every device. Our designers craft responsive, user-focused interfaces, building interactive Figma prototypes and reusable component libraries tailored for rapid website development. Early usability tests help pinpoint improvements before coding even begins. Regular design demos ensure every element matches your vision, guaranteeing your web application feels intuitive, professional, and aligned with users' expectations.

3. Development: Building high-performance solutions

We build robust web applications using modern stacks like React and Node.js. As a professional web development company, we ensure transparent communication with regular sprint demos, detailed pull requests, and open repositories. Concerned about scope creep? Our team manages changes transparently, clearly outlining their impact on timelines and web development cost. Thanks to agile practices, your project stays predictable, within Β±10% of CPI and SPI.

4. Testing: Delivering a bug-free web application

High-quality web development solutions demand bulletproof quality. Our QA team performs targeted tests, including browser compatibility, performance checks (page-load under 1.5 seconds), and rigorous security tests aligned with OWASP standards. With detailed documentation, we deliver stable web applications β€” achieving a 99.89% acceptance rate at launch.

5. Deployment: Launching with confidence

Launching your web development project is smooth sailing with our streamlined deployment process. Using continuous integration and deployment pipelines (Jenkins, GitHub Actions), containerization (Docker), and cloud platforms like AWS or Azure, we ensure minimal downtime during releases. As a professional website development company, we provide detailed deployment documentation and proactive risk mitigation to make every launch stress-free.

Clearing up your concerns

How do you handle cross-browser compatibility?

We design scalability into your web application’s architecture right from the discovery stage. By choosing modern, modular JavaScript stacks, cloud-based infrastructure, and containerization, we make sure your app can effortlessly handle high traffic and new features as you grow. Our proactive planning and stress testing mean your app easily adapts to increased demand without performance dips.

How do you ensure optimal web portal speed and performance?

Performance optimization begins at the architecture stage. We use lightweight front-end frameworks, optimized backend code, caching strategies, CDN integration, and rigorous performance testing. Regular stress testing, real-user monitoring, and continuous optimization ensure your website stays fast, responsive, and reliable β€” even during high-traffic spikes.

Can you meet our quality standards?

Definitely. We achieve a 99.89% acceptance rate across projects by strictly following PMI industry standards and tailoring QA processes for each web development project. Whether it’s simple ongoing testing or advanced CI/CD, regression, security, and stress tests, our approach ensures exceptional quality. Plus, with transparent processes and regular demos, you see proof of quality at every development stage.

How do you keep us in control throughout the process?

We use customized communication plans detailing roles, channels, and update intervals, giving you direct access to PMs and engineers. Weekly reports compare actual spending and progress against plans. As a professional web development company, we ensure full visibility into docs, wireframes, repositories, and Kanban boards. You always know exactly what's happening β€” no surprises, no experiments.

How will we retain expertise over the parts we outsource?

Expertise stays fully within your team thanks to structured knowledge transfer. Our web development company openly shares comprehensive documentation, detailed code comments, repositories, and training sessions. Our engineers collaborate directly with your developers during onboarding and beyond, ensuring your internal team confidently understands and maintains outsourced features β€” fully prepared for future development.

How can we be sure you’ll deliver exactly what’s agreed on?

Our proven web development process ensures zero delivery gaps. We document every feature, requirement, and wireframe upfront. Regular iterative demos and interactive prototypes allow real-time adjustments, ensuring alignment throughout development. Our web development consulting approach, transparent reporting, and proactive risk management guarantee you receive exactly what we agreed β€” 100% satisfaction, zero surprises.

Will the team stay consistent and familiar with our code?

Absolutely. Our engineers stay with us long-term (average tenure 3.8 years, churn just 5.5%), ensuring deep, ongoing familiarity with your web application and codebase. If someone new joins, structured onboarding and detailed documentation ensure smooth transitions. Team stability means consistent quality and in-depth understanding of your web development project.

How will we understand the outsourced code for maintenance?

We eliminate any knowledge gaps through transparent, detailed documentation and open access to code repositories, pull requests, and thorough inline code comments. Regular joint working sessions and direct communication with our engineers provide clarity at every step. Even after the web development project ends, you'll clearly understand every line of outsourced code, simplifying internal maintenance and ongoing updates.

Will language barriers affect communication?

Not at all. 98% of our clients come from the US and UK and consistently praise our team’s fluent English. Through direct communication with engineers, regular video meetings, and structured updates, language barriers are nonexistent. Clear, understandable communication is our standard, ensuring effortless collaboration and zero misunderstandings.

Will we retain full IP ownership of the product?

100% β€” your web application and its intellectual property are fully yours from day one. Our agreements explicitly guarantee that full ownership rights belong exclusively to you. No hidden clauses, no licensing restrictions β€” just absolute clarity. Everything developed, from code to design assets, documentation, and deliverables, belongs exclusively to you, ensuring complete freedom and full control.

How do you stay stable given the situation in Ukraine?

Our web development company has proven resilient, even through challenging times. We’re fully decentralized and energy-independent, with team members safely distributed far from conflict zones. Since 2022, we’ve scaled existing web development projects, signed new long-term contracts, and maintained stable staffing. Your website development services remain reliably on track, unaffected by external disruptions.

How do you keep estimates accurate and our budget on track?

Accurate web development cost estimates are at the core of our approach. With 100+ web apps built and countless features developed, we base our estimates on real-world data, not theory. We track CPI and SPI, proactively communicating any variance. Weekly budget reports clearly show planned vs. actual spending per feature. Any scope changes receive an immediate cost impact analysis and require your explicit approval before proceeding β€” ensuring zero unexpected costs, total predictability, and full budget transparency throughout your project.
