I grew up in Latvia and now reside in Valencia, Spain. I am a full-stack developer. As a Full-stack Developer, I seamlessly combine robust backend structures with intuitive frontend designs. My toolkit includes Nextjs, TypeScript, and Tailwind on the frontend, while on the backend, I utilize NodeJS, Supabase with POSTGRES, Google Cloud, and Vercel. State management and security are also crucial in my work, where I incorporate Zustand, Context, JWT Tokens, and Row-level Security. On the frontend, I'm adept at leveraging the capabilities of Nextjs, TypeScript, and Tailwind, ensuring a seamless user experience marked by crisp design and responsive interactions. When it comes to the backend, I've anchored projects using NodeJS and Supabase, with POSTGRES as the backbone. I'm also familiar with cloud infrastructure, primarily using platforms like Google Cloud and Vercel, which help scale and deploy applications with efficiency. State management is pivotal to any project, and I've efficiently employed Zustand and Context to manage the complex states of the applications I've worked on. But beyond just building, I believe in fortifying. My emphasis on security integrates JWT Tokens and Row-level Security (RLS), ensuring that user data remains both accessible and protected. In essence, I'm not just a developer; I'm a solution architect, striving to bridge user needs with technological finesse.

I've been working on this for +13 years, from desktop development (C++, QT, .NET) to mobile development (Cordova, Ionic), game development (Unity, Gamemaker) and for the last years, more focused on web development. Almost all my web projects are made in PHP, MySQL and HTML, CSS and Javascript (mostly jQuery) but I have a little experience with Angular and TypeScript too. I used Codeigniter and some CakePHP and Symfony, long time ago. Also, I have some experience with Wordpress, Prestashop, Python, Arduino, Google Cloud... My role was usually a full stack developer. I did frontend and backend, HTML, CSS, Javascript, PHP programming and database creation. I installed and configured a couple of Linux servers too and took some first steps with Python.

From wire framing and mood-boarding, through designing beautiful, fully-responsive sites, to coding custom WordPress themes and plugins from scratch, I will provide you with creative and technical support to help you meet your specific business goals via your website. Read on to learn more... 𝗪𝗼𝗿𝗱𝗣𝗿𝗲𝘀𝘀 𝗧𝗵𝗲𝗺𝗲 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 ᕕ( ᐛ )ᕗ Without doubt, the key component of any WordPress site. Bringing together ʜᴛᴍʟ, ᴘʜᴘ, ᴄꜱꜱ and just a pinch of ᴊꜱ, I am highly skilled at building custom WordPress themes to meet the specific requirements of each client. I prefer not to reinvent the wheel, so when building a WordPress theme from scratch, I always reach for a "starter theme" of my own creation which I have compiled, curated and tweaked, project after project, for over a decade. 10 years of great ideas, best practices, cool effects and useful design patterns are ready to kickstart your next project! Happy with your existing theme and just want to add a little something special? I will build you a WordPress Child Theme to safely hold the modifications, without risking breaking anything in your main theme and allowing your to update with confidence. All my themes are: ✔ Fully responsive over a range of devices ✔ Accessible ✔ SEO optimised ✔ Performance optimised ✔ Secure 𝗪𝗼𝗿𝗱𝗣𝗿𝗲𝘀𝘀 𝗣𝗹𝘂𝗴𝗶𝗻 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 (/¯◡ ‿ ◡)/¯ I regularly build bespoke WordPress plugins for clients to bring additional functionality to their sites. By placing the custom code in a plugin, the client has the flexibilty to change themes without losing the customisation. ᴄᴀꜱᴇ ꜱᴛᴜᴅʏ We all know native WordPress search sucks, right? To provide Khyentse Foundation with robust on-site search, I built a custom WordPress plugin to integrate the Algolia Search API, bringing context-aware results and Google Maps integration. Although most of my plugin work has been for clients, I have also created two free open-source WordPress plugins which are available to download and install via the official WordPress Plugin Directory. ✔ Air Quality Data from Foobot — display air quality data via the Foobot API. ✔ Multilingual Comment Moderation — send comment moderation notifications to different email addresses based on post language (WPML add-on) 𝗧𝗵𝗶𝗿𝗱-𝗽𝗮𝗿𝘁𝘆 𝗣𝗹𝘂𝗴𝗶𝗻 𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 (•ᴥ• )́`́'́`́'́ ⻍ As well as building my own custom plugins, I have many years of experience working with a wide range of third-party WordPress plugins, including: ✔ WooCommerce ✔ MemberPress ✔ WPML ✔ Advanced Custom Fields (ACF) ✔ LearnDash ✔ Yoast SEO ✔ The Events Calendar ᴄᴀꜱᴇ ꜱᴛᴜᴅʏ CABPExpo needed to extend the out-of-the-box functionality of the WP Events Manager plugin to work with non-standard attendee badge templates, as well as optimizing the workflow for their specific requirements. I achieved this by creating custom templates and making use of the plugin's hooks and filters. 𝗧𝗵𝗶𝗿𝗱-𝗽𝗮𝗿𝘁𝘆 𝗧𝗵𝗲𝗺𝗲 𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 (っ ˆڡˆς) While my main focus is building bespoke WordPress sites, I am also experienced at working with third-party themes, such as Divi. I can build complex layouts using page builder tools, but, when required, I am happy to create a child theme to safely add more advanced customisations.
