Web Developer
I build websites that are fast, accessible, secure, and enjoyable for users while meeting business goals
I am Alex Costin, a London-based Web Developer with master-level expertise in Drupal and Bootstrap, HTML/CSS, and responsive front-end architecture. I combine strong technical skill with problem-solving ability, communication, and a user-focused mindset so I can build websites that are fast, accessible, secure, and enjoyable for users.
I do not just write code that works; I create conversion-ready, SEO-optimised websites that look exceptional, load fast, and consistently outperform industry benchmarks. At TuneMyWebsite, I build penalty-free "Perfect Websites" that combine maximum landing page quality with exceptional SEO strength, and I set new standards by getting pages to first position in search results in as little as 11 days, even in highly competitive niches.
Web Developer About Me
I stand out by combining strong technical skill with problem-solving ability, communication, and a user-focused mindset. I do not just write code that works; I build websites that are fast, accessible, secure, and enjoyable for users while meeting business goals.
I diagnose complex issues and create creative, repeatable solutions that prevent future problems. I catch tiny errors before launch and ensure every button, form, and interaction works as intended, because small issues can damage trust and conversion.
I translate technical details into plain language for clients, designers, and managers, making collaboration smoother. I stay open to new languages, frameworks, and tools, and constantly ask questions to learn, so my work stays modern and effective.
I take responsibility for my tasks, test my code, support it after deployment, and escalate issues when needed. I understand user experience principles and have an eye for design, balancing aesthetics with functionality so the site feels both professional and human.
I use data, such as 1 second load time, user behaviour, and conversion rates, to optimise performance and improve the site. I am comfortable in uncomfortable situations and can handle the unknown without being tied to one specific tech stack. I am often "T-shaped": deep expertise in one area, but broad enough to understand algorithms, DevOps, architecture, and how to evaluate tools.
I think through problems from multiple angles, compare approaches, and explain why I chose one solution over another. For me, making something that "works" is not enough; I care about readability, performance, and maintainability, because code lasts longer than any single release.
Web Developer Services
Drupal back-end development
I combine a powerful Drupal back-end with a clean, responsive Bootstrap front-end to launch fast, conversion-focused websites that search engines love. I architect custom themes, components, and modules that scale with business needs.
Front-end architecture
As a master HTML/CSS developer, I build responsive, accessible layouts that work across devices and screen sizes. I focus on performance, clean code, and maintainability, ensuring the site feels smooth and professional.
Performance and UX optimisation
I optimise sites for technical excellence, delivering frictionless UX, strong Core Web Vitals, and robust performance at scale. I use data like 1 second load time, user behaviour, and conversion rates to improve the site and drive results.
SEO-aware development
I build conversion-ready, SEO-optimised websites that look exceptional, load fast, and consistently outperform industry benchmarks. I am able to architect "feeder websites" to amplify off-page SEO, capture new traffic streams, and generate fresh leads and clients.
Quality assurance and support
I catch tiny errors before launch and ensure every button, form, and interaction works as intended. I take responsibility for my tasks, test my code, support it after deployment, and escalate issues when needed.
