    I'm available for a new project and can start work as soon as needed! Hello! I am Niko, a seasoned Software Engineer with a versatile 16-year career in the tech industry. During my career, I helped 70+ clients achieve their goals. My experience spans many PHP environments, from sophisticated frameworks like Laravel to the foundational native code that underpins them. Here's the value I bring to your projects: ⚡ PHP Mastery Across Frameworks: While the Laravel Framework is a tool of choice for many projects due to its robust features, I am equally skilled in working with Symfony, CodeIgniter, and other PHP frameworks. My adaptability ensures that I can easily select the best tool for your project's specific needs or work within your existing framework. ⚡ Framework-Agnostic Development: Beyond frameworks, I excel in crafting bespoke solutions with pure, native PHP. This flexibility means that the limitations of any single framework don't constrain your project and can be tailored precisely to your requirements. ⚡ Quality Assurance Through Testing: Whether working within a framework or with native PHP, my commitment to quality is demonstrated through rigorous testing with tools like PHPUnit. This ensures that every component of your application is reliable and robust. Full-Stack Capability: ⚡ My skills extend through the full stack, with proficiency in front-end technologies such as HTML, CSS, Bootstrap, JavaScript, and Vue.js. I create seamless user experiences that complement the solid back-end architecture. ⚡ Data Handling Excellence: With extensive experience in databases like MySQL and PostgreSQL, caching with Redis, and searching with ElasticSearch, your data will be managed with the utmost efficiency and reliability. ⚡ Scalability with Asynchronous Systems: I integrate message brokers like RabbitMQ for systems that demand high-throughput processing and scalability, ensuring that your application performs optimally under any load. ⚡ DevOps Integration: By leveraging modern DevOps practices and CI/CD pipelines, I enhance the software development lifecycle to ensure your product evolves quickly and smoothly from development to deployment. ⚡ Clear and Effective Communication: I may not be a native English speaker, but I possess a strong command of the language, particularly in technical contexts. This ensures we stay on the same page throughout the development process. Strategic Problem-Solving: My passion for tackling complex problems is complemented by a well-rounded understanding of software architecture and system operations, ensuring that I deliver not just code but comprehensive solutions. By partnering with me, you're not just getting a PHP developer or Laravel Developer; you're gaining a flexible and strategic ally dedicated to propelling your business forward with technology. I'm excited about bringing my broad PHP expertise to your project and am ready to deliver a product that stands out for its quality and craftsmanship. Ready to create something great together, Niko

    Hey there, My name is Jonathan and I offer services as a fractional CTO, full-stack developer, and personal privacy consultant. Let me tell you a little bit about how I got here... I've been working with the web stack since I was young but started out my career about 12 years ago when I started working with WordPress and front-end development. I was able to use those skills to land myself a job at a Silicon Valley tech startup as a front-end engineer. I worked across the web stack using the EmberJS and Rails frameworks. Eventually, I was offered a role as the CTO /technical co-founder of a Real Estate Tech startup. I jumped at the opportunity. It was there that I developed skills as a backend developer, infrastructure architect, and as well as a leader. I built our SAAS application from the ground up and worked across the stack implementing agile methodologies and business processes across multiple domains. We grew that company over the course of 4 years and successfully exited in 2021. After my exit, I stayed with the company leading development and product management. We grew the team from 2 developers to 7 and worked to scale the product and infrastructure. My work included scoping technical projects, leading daily standups, code reviews, creating and managing tickets, and holding interviews for both product and development. Currently, I work as a Fractional CTO. I use the skills I've learned to help bolster teams with a seasoned software development mind. My skills range from infrastructure to full-stack development, building development teams, leading a development team from the product or dev side. I also dive deep into the business side: setting up processes, implement best practices, reducing costs, and more. I specialize in taking products from 0 to 1 or idea to inception as well as jumping in to take over projects stuck in development hell in order to get them back on track so that they deliver on time and on budget.
