Hire the Best Firebase Developers
in Ireland

Hey there! I come from a background in structural / civil engineering but have been working as a software developer for over 5 years now. During that period, I co-founded a startup, worked for a ticket reselling company and have built several complex web apps for clients both here on UpWork and elsewhere. I have a highly client-focused approach and can help you with the following: ● Building out a highly responsive web app to pixel-perfect accuracy from a design. ● Creating your web app from scratch with only an approximate idea of what you want. ● Consultating on your idea and the best way to implement it. ● Providing advice on technology choice and potential benefits and drawbacks. ● Hosting a headless CMS so that you can update content by yourself. ● Building a fullstack web app including for mobile with React Native. ● Integrating with third-party APIs. ● Obtaining an optimized SEO score as measured by Googles PageSpeed Insights. Another important way in which you'll benefit is by very timely and clear communication from me. This includes being added to the project on GitHub so you'll be aware of my contributions and provision of the URL where the project is hosted so you can track development. For larger projects, I'll itemise tasks on a Trello board so you have full oversight on the progress of each item and position in the queue. Either way, I'll always keep you updated and ensure that all deliverables are met. If you want to discuss your project requirements and how I can help you reach your goals, please don't hesitate to contact me and we can arrange a free zero-obligation consultation. Thanks for reading and I hope to hear from you soon. Lucas

Dear Sir/Madam, Good day. Please regard this letter as an introduction for your consideration. I am interested in exploring employment opportunities with your organisation on either a permanent or contractual basis. I have always had a strong interest in technology and how modern digital systems operate. My attention to detail, analytical mindset, and inquisitive nature have led me to pursue extensive education and hands-on experience in software development and cybersecurity. I successfully completed a Diploma in Full Stack Software Development with Code Institute, where I received formal training in HTML, CSS, JavaScript, Python, Django, relational databases, and modern web application development. During the program, I built five portfolio projects, including a fully functional eCommerce platform developed for a local business, and also participated in collaborative team hackathons. My projects are available on my GitHub portfolio. In May 2026, I completed a Bachelor of Science (Honours) in Contemporary Software Development at. In addition, from January 2025 to November 2025, I completed a full-time Cybersecurity (CompTIA Track) programme at. The programme included modules in IT Fundamentals, CompTIA Network+, Microsoft Certification, Cybersecurity Ethics, Ethical Hacking (CEH v13), and IT Support. Alongside my technical education, I have developed strong analytical and problem-solving abilities, effective time management skills, and the ability to communicate and work professionally with people at all levels. I would greatly appreciate any information regarding potential employment opportunities within your organisation. Thank you for taking the time to review my application. I look forward to the opportunity to discuss my qualifications and experience further. Yours faithfully, Sergiy
