Hi, I am Sam.
I’m not just here to list buzzwords. This is the raw list of how cool I am (technically speaking). I’m a fast learner with a sharp eye for building real, scalable solutions, not just shipping code for the sake of it. I’ve co-founded and built a company from scratch, growing it to a team of 6, so I know what it means to work across roles, take ownership, and deliver in a team setting. Whether it’s product, code, or architecture, I focus on collaboration, clarity, and shipping.
Technical Stuff:
React & Vue.js
Advanced expertise in building responsive, high-performance interfaces with React and Vue.js, using modern state management tools such as Pinia, Zustand, and Jotai
TypeScript & JavaScript
Strong command of TypeScript and JavaScript for scalable frontend and full-stack application development
CSS, SASS & Design Systems
Extensive experience with CSS3 and SASS, specializing in large-scale design systems using SASS or native CSS features like custom properties, nesting, and modern functions for adaptive dark/light modes. Familiar with scalable CSS architecture patterns including BEM and utility-first methodologies
UI Development & Frontend Tooling
Skilled in component-driven UI development with tools like Storybook and seamless REST API integration. Experience with templating engines and frontend frameworks such as Liquid (Shopify), Mustache (legacy stacks), Gatsby, Next.js, and Nuxt
Mobile & Cross-Platform Development
Experience with React Native and Expo for building cross-platform mobile applications, as well as Electron for desktop environments
Node.js & Backend Services
Proficient in backend development with Node.js and Express.js, including RESTful API design and integration in full-stack applications
Cloud Infrastructure & Auth
Practical experience deploying with AWS (Lambda, Amplify) and implementing secure authentication using OAuth, JWT, and related protocols
Python and Automation
Basic experience using Python for scripting tasks such as data logging, web crawling, and automating workflows

Portfolio
isitfake.news
My team and I developed isitfake.news, a web platform that analyzes and rates the trustworthiness of online news articles. We built the frontend using Nuxt.js, incorporating responsive design and Lottie animations to create a seamless and engaging user experience. On the backend, we used AWS services including SageMaker to deploy machine learning models that automatically evaluate article credibility using natural language processing. The platform combines multiple data sources to generate transparent, explainable scores. You can learn more at isitfake.news or krekeny.com.

New Krekeny Header
corporate website with a focus on delivering a personalized and visually engaging first impression. We built a dynamic header section composed of multiple Lottie animations that seamlessly transition into each other, forming a fluid narrative. The animation sequence illustrates the idea that every user has a unique journey, with individual preferences, content needs, and interaction styles. The concept and execution combine storytelling, design, and code to reflect the platform's commitment to user-centric experiences.
