Full-Stack Web Developer Hi, I'm Elvis. I'm a Full-Stack Web Developer with 9 years of experience building all kinds of Web, Mobile, and Desktop applications. I've worked with clients from many different industries, helping them turn their ideas into real, functional products. Most of my work is around modern web technologies — HTML, CSS/SCSS, JavaScript/TypeScript, Python, and .NET C#. I enjoy building clean, user-friendly frontends and solid, reliable backends. Along the way, I've integrated lots of third-party services like PayPal, Stripe, WhatsApp, Telegram, Google APIs, and more. I'm comfortable working with databases such as SQL, MySQL, PostgreSQL, and MongoDB. I've also deployed projects to AWS, GCP, Vercel, Hostinger, and other hosting platforms. Beyond traditional development, I work on AI code evaluation — creating rigorous coding tasks, writing test suites, reviewing AI-generated code for correctness, and performing detailed QA analysis. This involves deep code review across multiple languages, writing technical specifications, and verifying everything through Docker testing pipelines. If you already have UI/UX designs, I can bring them to life using React/Redux, Angular, Material-UI, Nebular, Bootstrap, and similar tools. Other tools and skills I use regularly: Git (advanced workflows — patches, diffs, rebasing, multi-repo work) Docker for testing and deployment Technical writing — specs, QA reports, task descriptions A few things about how I work: I follow modern standards and good development practices I like writing clean, organized, readable code I'm persistent and always learning I'm honest about my hours and prefer long-term collaborations Feel free to check out my portfolio and reviews. If you think I might be a good fit for your project, I'd be happy to talk.

You have a great idea for an eCommerce platform, marketplace, or SaaS. You hire a developer. They build something that “works.” But months later — no customers, no revenue, no growth. I’ve seen this happen many times. That’s exactly where my approach is different. I help businesses build and grow platforms designed for real revenue — not just development. Over 14+ years and 100+ projects, I’ve worked on: ✔ Multi-vendor marketplaces reaching 6-figure GMV ✔ AI-powered product catalog systems ✔ Healthcare SaaS platforms (UK & global clients) In several cases, I’ve supported businesses from early-stage launch to $100,000+ annual revenue within the first year — by combining development with the right product and marketing strategy. Most teams stop at “it works.” I focus on building platforms that scale and deliver real business impact. You work directly with an experienced architect, backed by a strong in-house team — where development and marketing work closely together from day one — covering: • Strategy • Design • Development • Marketing & Growth • Ongoing support If you’re looking for a partner who understands both technology and growth, let’s talk.
