Hire the Best Outsourced Developers
in Bosnia and Herzegovina

I build everything from complex web applications with heavy business logic to pixel-perfect, responsive websites that rank and convert, and I treat both with the same level of engineering rigor. 10+ years in full-stack development taught me that the best projects happen when architecture decisions, user experience, and business goals are all aligned from day one. What I bring to the table: I architect and build complete web applications from scratch, database modeling, REST API design, authentication systems, role-based access control, complex business logic, payment gateway integrations, third-party API integrations, the full picture. Whether it's a multi-tenant SaaS platform, a custom e-commerce solution, or an internal business tool — when something needs to scale, handle edge cases gracefully, or process data in ways that aren't straightforward, that's where I do my best work. On the frontend, I'm equally obsessive. Figma-to-code with pixel-perfect accuracy, fully responsive across every breakpoint, complex animations with GSAP and Framer Motion that feel native, and interfaces where every interaction is intentional. I implement technical SEO at the code level — structured data, schema markup, Core Web Vitals optimization, semantic HTML, crawlability — because I've worked closely enough with marketing and SEO teams to know it directly impacts revenue. Tech stack: → Frontend: React, Vue.js, Angular, Svelte, TypeScript, Next.js, GSAP, Framer Motion, Tailwind CSS, HTML/CSS/JS → Backend: PHP (Laravel, Yii2), Node.js → CMS/eCommerce: WordPress, WooCommerce, Shopify, Webflow → Databases: PostgreSQL, MySQL → DevOps: Git, CI/CD, AWS, Docker, Linux server management Where I fit best: → Full application builds — from initial architecture through deployment and maintenance → Complex backend systems — workflows, data processing, role-based access, API integrations, payment systems → Pixel-perfect, responsive UI with advanced animations and polished UX → Technical SEO and Core Web Vitals optimization baked into the codebase → Bridging the gap between development, design, and marketing teams → Legacy codebase modernization, refactoring and migrating to modern tech stacks without starting from zero The short version: I'm equally comfortable designing a database schema for a multi-tenant SaaS app and fine-tuning a 60fps scroll animation. Most developers lean one way — I don't. 100% Job Success · $100k+ earned · 25+ long-term clients Got a project that needs both depth and polish? Let's talk.

Need a new website or something on your current site changed? Not satisfied with your workflow? Have an error or an issue with a plugin? I provide expert design and development to everything related to WordPress, PHP and Angular 2+ (also other JS frameworks). I have 5+ years of experience working on the web! I will design, build, secure, repair, and SEO empower your websites so they look great, load lightning fast, and rank high in search engines. I pride myself on the following across all of my projects: Open Communication - There are many people out there who know how to code or work on WordPress. Not everybody knows how to listen to your needs and requirements, follow up with you promptly, meet deadlines, or talk about your website in a way that's not filled with technical fluff that you won't understand. In addition to these, I always strive to be open, friendly, easy, and fun to work together. Honesty 1st - I'm going to be upfront with you about your project. I will give you an accurate estimate of the time and cost before we begin. If it's something I cannot do, I will let you know that the project does not fit my skills. As a one-person freelancer, I love giving individualized attention to my clients. Best Practices - There's many incredibly sloppy coding out there, events from major companies, especially on WordPress sites. Many people overload their sites with too many plugins, use slow, poorly design themes, or take shortcuts that only lead to problems down the road. I make an effort to stay up-to-date on current best practices and code not only in a way that works but in a way that will make your site as fast, secure, and easy to use as possible. Rich Experience - I've been building WordPress and Angular websites for a long time and am experienced in WordPress, Angular 2+ (currently working on v15 w/ standalone components), CSS3, WooCommerce,digital marketing & analytics, web hosting, domain, and DNS support...

Greetings stranger, You're probably here because you need someone *cough* me *cough* to write a code that would make the difference! Or find the line that's been bugging you and fix the code that you have. Well, you're in luck! My goal is to offer wide range of services to some of the most successful UpWork employers. I've been working outside of UpWork for 11 years and I would like to utilize my skills to provide honest and exclusive services. I possess top notch skills in the following fields: - PHP: Building code from scratch for websites & other purposes, applications, SaaS, automatization... - CMS: Customizing suggested templates or creating practical and efficient solutions to suit all your needs in WordPress, WooCommerce, Shopify, Joomla, Drupal... Basically every CMS there is. - Ethical Hacking & Security: Regardless whether you simply want to test your assets or find & neutralize any potential or ongoing threats, I'm your guy. - Not-so-ethical Hacking: No questions asked, client discretion guaranteed. Skills tested and held against every law enforcement organization in the state and several Information agencies from other countries in region. - Data Mining, Scraping & Management: Automated or not, whichever way you prefer to collect valuable information from your property or some other assets, while also validating, rearranging & storing all data accordingly. You'll find it useful to know, I've always preferred to think through my every step, prior to taking action. This resulted in becoming highly valuable asset to every team, which comes at a price of course. Because of that, you will most likely prefer hiring me to solve that thing which "everyone can do", but is actually the hardest part of your whole setup. Experience has proven that you most likely need me to tackle down these for you: - SSL Issues - Cloudflare & DNS Settings - Website Migration - Page Speed & Responsiveness Optimization - Database Management & Security - Third Party Integrations So don't hesitate, for I could be the solution for that issue holding down your entire business. Cheers.
