Clients include Toyota, Vivo, Somany Bathware, and 600+ SaaS, fintech, e-commerce, and ed-tech teams. What I Create โก Lottie Animation โ Lightweight, dev-ready Lottie JSON files for web and mobile apps. I create onboarding flows, loading animations, micro-interactions, UI state transitions, empty-state illustrations, success/error feedback animations, and in-app storytelling sequences. Every file is optimized for size and performance โ typically under 50KB โ and tested across platforms before delivery. ๐ฎ Rive Animation โ Interactive Rive components and character animations with real-time state machines. I build toggle animations, interactive buttons, animated icons, onboarding characters, and gamified UI elements that respond to user input. Built for performance, designed for seamless developer handoff with clean state machine architecture. ๐ฌ Explainer Videos โ Script-to-screen explainer videos for SaaS, fintech, healthcare, and product launches. I handle concept development, scriptwriting support, storyboarding, illustration, voiceover direction, and final animation. Every video is designed to simplify complex ideas, increase landing page conversions, and reduce customer support load. Styles include 2D character animation, flat design motion graphics, whiteboard animation, and isometric explainer videos. ๐จ Motion Graphics & After Effects โ Logo reveals, brand intros/outros, social media video ads, product launch teasers, event promos, animated infographics, and kinetic typography. Whether it's a 5-second logo sting or a 90-second ad campaign, I match your brand guidelines and deliver broadcast-quality motion design. ๐ฑ UI/UX Animation & Prototyping โ App transition animations, navigation flows, scroll-triggered effects, and interactive prototypes. I bridge the gap between design and development by creating animations that developers can implement pixel-perfectly using Lottie, Rive, or CSS/SVG specs. Industries I Work With I've delivered animation projects across SaaS, fintech, e-commerce, ed-tech, healthcare, real estate, logistics, cybersecurity, HR tech, and consumer brands. This cross-industry experience means I understand how to communicate complex workflows, technical products, and abstract services visually. My Process โ Built for Async, Remote Teams 1. Discovery & Concept Alignment โ I review your brief, ask targeted questions, and define the creative direction, audience, and goals before any design work begins. 2. Script & Storyboard โ For explainer videos, I collaborate on the script or write from scratch, then deliver an illustrated storyboard for approval. For UI animations, I share motion briefs or style frames. 3. Animation Production โ I animate in After Effects, Rive, or directly for Lottie export depending on the deliverable. You'll see progress at key checkpoints โ no surprises at the end. 4. Feedback & Revisions โ Structured revision rounds with clear communication. I respond to feedback within 0โ4 hours during working days. 5. Final Delivery โ Production-ready files delivered in the format your team needs: Lottie JSON, Rive files, After Effects projects, MP4, MOV, GIF, or WebM. All assets are optimized for fast loading, smooth playback, and easy integration. Tools & Technical Stack Adobe After Effects, Bodymovin/Lottie, Rive (with state machines), Adobe Illustrator, Spline, Photoshop, Audition. I'm comfortable working alongside developers using React, Flutter, Swift, and Kotlin โ and I ensure every animation file integrates cleanly into your existing tech stack. Why Clients Keep Coming Back โ I don't just animate โ I think about why something moves. Every animation serves a purpose: guiding attention, simplifying a concept, increasing engagement, or driving a specific user action. โ I communicate clearly and proactively. You'll never have to chase me for updates. โ I deliver on time, every time. Deadlines are non-negotiable for me. โ I optimize for the real world โ file size, load time, cross-platform compatibility, and developer handoff are part of my standard process, not afterthoughts. ๐ฉ Send me your project brief โ I'll respond with a clear plan, timeline, and estimate within 4 hours.

8 years. No shortcuts. No plugin-stacking. Most developers hand you a site that works until the next WordPress update breaks it. I build platforms that handle scale โ 10,000+ SKU integrations, zero-downtime migrations, custom backend logic that doesn't crumble when traffic spikes. I work with founders and agency directors who have outgrown generic solutions and need a technical partner who understands business logic, not just syntax. => Problems I Solve Your site is technically broken and it's actively costing you revenue You have a complex API or data sync requirement that other developers walked away from You need design-to-code execution โ Figma or XD files converted into lightweight, responsive templates that pass Core Web Vitals You're running multiple domains or platforms that need to be consolidated without losing SEO equity Your current WordPress setup breaks every time there's an update because it was built on duct-tape plugins If any of those hit close to home, keep reading. Core Technical Expertise ------------------------------- Backend & Custom Development ========================== PHP (Hooks, Filters, Custom Plugin Development) Shopify Liquid โ bespoke section logic, custom storefront features Python, SQL โ data pipelines, automation scripts REST API integration and custom API engineering WordPress Architecture ==================== Advanced Custom Fields (ACF), Custom Post Types, Custom Taxonomies WooCommerce โ complex B2B checkout flows, product filtering, bulk pricing Custom plugin development where off-the-shelf solutions fail Performance & SEO ================ Technical SEO auditing and architecture LCP, CLS, and Core Web Vitals optimization Clean-code builds that load fast without sacrificing functionality DevOps & Workflow ================= GitHub Actions, CI/CD pipeline setup Staging environments, version control, deployment automation Case Studies =========== Koplanda (Industrial E-Commerce) Engineered a scalable WooCommerce platform for a Dutch industrial equipment supplier. Built complex product filtering and a streamlined B2B checkout flow to handle high-value transactions across a 10,000+ SKU catalog integrated via API. Epilog Laser (Localized Enterprise) Built a high-authority localized site for a global laser systems brand. Focused on technical SEO architecture and lead generation funnels targeting high-intent enterprise traffic in the Dutch market. Spotwork (SaaS & Recruitment) Developed an API-driven recruitment platform with dynamic job filtering and a clean UX designed to convert. Integrated real-time data feeds to keep listings current without manual intervention. Deline Media (Agency Flagship) Delivered a performance-optimized agency website with pixel-accurate design execution and sub-2s load times. Built to reflect the agency's brand authority while maintaining technical rigor under the hood. Who This Is NOT For I maintain a 100% Job Success Score by turning down work that isn't the right fit. Skip the invite if: You need a "quick fix" done cheap and fast โ that's not how I work You're not open to technical communication about architecture decisions Your budget doesn't reflect the business impact you're expecting You want someone to install pre-built plugins and call it a solution Let's Talk ========= If you're ready to build something that scales, here's how to move forward: Click Invite or Message =================== Share a link to your current site โ or your Figma/XD files if you're starting fresh Tell me the one technical problem that's costing you the most right now I review every message personally and respond within 24 hours.

JSON FAQs
What is JSON?
JSON (JavaScript Object Notation) is a data interchange format that has vastly improved server-to-browser communicationsโespecially when it comes to AJAX. Itโs a language thatโs similar to XML, syntactically identical to JavaScript code, and the fastest data-interchange format to be used with AJAX (Asynchronous JavaScript + XML), making it not far behind HTML when it comes to skills no front-end developer should go without.
JSON is a syntax designed to store and move data thatโs sent between server and browser. Itโs similar to a markup language in its syntax and how itโs used, but itโs not a markup language at its core. If you think of how XML functions in the scheme of a siteโXML describes elements of data, while HTML displays that dataโJSON does the same thing, just in a more streamlined way, both for the developer and the browser.
Why hire a JSON specialist?
A front-end developer who specialists in JSON can help you to create interactive, high-performance sites and apps.
JSON was the first format that allowed servers and browsers to communicate without a browser plug-in like Flash or Java. But where JSON really shinesโand sets the standardโis how it functions within AJAX operations. AJAX essentially allows parts of a web page to be updated without requiring a full-page refresh, something that vastly changed the way users interact with web applications. It immediately solved problems that were caused by limited bandwidth, prevented server overload, and kept things from slowing down in the app.
AJAX was originally created in the mid-2000s with XML as its data interchange format. In that first model, after a page was loaded, new data could be called up from the server using XML as the data interchange format. JSON has improved the data retrieval process by being front-end compatible by nature with its JavaScript roots. With JSON and JSON Web Services, AJAX runs fasterโitโs instantaneous and highly efficient.
JSONโs core differentiator is that itโs written in JavaScript syntax, but itโs text-only. This allows it to logically skip a front-end step: Whereas XML requires a parser to be read by a JavaScript program, JSON doesnโt require any extra software. Itโs a subset of JavaScript, and so itโs compatible with the front end, right off the bat. A JavaScript program will convert JSON elements directly into JavaScript objects.
Like XML, JSON:
- Is โself-describing,โ meaning humans can read it
- Uses hierarchical values
- Can be read by many programming languages
- Is able to be โfetchedโ by an XMLHttpRequest
How JSON is different than XML:
- Doesnโt require an end tag and wonโt โbreakโ without one
- Is shorter to read and quicker to write
- Uses arrays, which are logical ways to bulk similar data formats in an element
