Welcome to Dannenhauer Labs! Full Stack Developer | DevOps | Selenium Programming Languages: Java, Python, TypeScript, C#, PHP, GO, SQL Github Achievements: - Arctic Code Vault Contributor - Pair Extraordinaire - Pull Shark - Yolo Github Username: crypto-hippo Hi, I'm Dylan, a highly experienced Full Stack Developer with 6+ years of hands-on experience building scalable, maintainable web applications for clients across a wide range of industries. I specialize in crafting seamless user experiences on the frontend using React, Vue, Next.js, Nuxt.js and developing robust, secure backends with Java (Spring Boot), Python (Flask & FastAPI), and Node.js/Express. Currently diving into the Astro framework. I’ve helped businesses launch MVPs that generate revenue, revamp legacy systems, integrate third-party APIs, and build complex dashboards and SaaS platforms from the ground up. My work consistently emphasizes performance, clean code, and maintainability. Core Skills: Frontend: React, Vue, Next.js, Nuxt.js, TypeScript, Tailwind, Material UI, HTML5, SCSS Backend: Java (Spring Boot), Python (Flask, FastAPI), Node.js/Express, Astro, Next/Nuxt SSR DevOps: Docker, Kubernetes, Nginx, Apache, Linux System Admin Databases: PostgreSQL, MySQL, SQLServer, MongoDB, Firestore, Supabase, Firebase I'm Top Rated Plus on UpWork, with a track record of clear communication, on-time delivery, and client satisfaction. Whether you need a full-stack partner for a long-term project or a specialist to knock out specific features, I'm ready to help. My self-driven and self-taught approach to studying computer science is what made this dream possible. Web Scraping & Web Automation. In addition to full stack development, I have extensive experience in web scraping and web automation with Selenium. I’ve built dozens of high-performance tools for tasks like product monitoring, data extraction, and browser automation. One of my standout projects was a Windows application built in C#, Winforms, and Bunifu that launched parallel headless Chrome browsers to automate checkouts on Supreme New York, enabling users to secure limited-edition drops with speed and precision. My automation work spans a wide range of use cases, including crawling Amazon product listings, finding vehicles to flip on Craigslist, gathering market data on boats and funeral homes, as well as tracking competitor pricing in real time. Whether it’s navigating complex DOM structures, avoiding detection mechanisms, or designing tools for non-technical end users, my ability to automate the web efficiently and reliably is unmatched. Let’s build something great together! I am just getting warmed up so take advantage. Cheers, Dylan

15+ years building production-grade mobile applications that scale, perform, and ship reliably in real-world environments. I work as a Senior iOS Engineer, partnering with startups, scale-ups, and enterprise teams — from greenfield development and architecture through to modernising legacy codebases. My focus is on clean architecture, performance, and long-term maintainability. Native iOS is my core expertise (Swift, SwiftUI, UIKit), complemented by 3+ years of hands-on Android development in Kotlin. Since 2020, I've been applying Kotlin Multiplatform (KMP) to share business logic across iOS and Android while keeping fully native UIs — improving delivery speed without sacrificing platform quality. I've built mobile systems end-to-end across the SDLC, including: - Architecture & system design - Native iOS & Android development - API integration & backend collaboration - Legacy codebase refactoring & migration - Performance optimisation & production stability Beyond mobile, I've worked across backend APIs, web frontends, and Bluetooth / IoT integrations — giving me a strong product-level engineering perspective. I integrate quickly into teams, communicate clearly across product, design, and engineering, and focus on predictable delivery and maintainable outcomes.

The last five years I spent working for Upwork itself as Sr. iOS Developer, developing its iOS app. I’ve been writing iOS applications for more than 10 years. I enjoy creating great software with user friendly UI. At every project I pay special attention on design, architecture, code support. I have professional knowledge of development in most of iOS Frameworks in all iOS layers. I’m responsible and focused on goals. Always trying to finish every project I work on. I graduated from Moscow State University of Economics Statistics and Informatics in 2009 as a mathematician and programmer. Several years I spent working in J2EE field, after that I started working as iOS developer. Several finished projects on the AppStore: Upwork, BoardMaps, Plain flashcards, Avtodor, QTickets. The first three are written in swift. I always try to find time to learn something new, I follow several projects on Github (my github profile - sidslog). Sometimes I participate in discussion on StackOverflow. I try to visit as many conference as I can or watch videos from this conference (WWDC is my favorite).
