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

The longer sit-down version:
Nice to meet you! I'm Jake. People love working with me because of my collaborative spirit, open communication, and efficiency. Some of the work I've done includes:
Revenue Growth: Directly recovered $38,000 in revenue for a recruiting organization by building a service that identified back door hires.
AI & Automation: Architected an AI-powered voice agent for behavioral health clinicians that reduced their data collection process from 2 hours to 2 minutes.
Scalable Systems: Engineered an appointment reminder service that scaled to over 100,000 daily messages for hospitals while cutting latency by 40% and reducing database load by 80,000 queries using Kafka.
High-Impact Engineering: Reduced a legacy codebase by 90% while improving performance, testing, and maintainability.
Reliability at Scale: Designed a Redis caching and queuing systems that improved performance, lowered costs, and kept systems running smoothly under high load.
I specialize in taking complex technical challenges, breaking them down into simple solutions, and delivering fast, reliable results. Whether it’s scaling infrastructure, integrating AI, or building automation that saves time and money, my goal is to help your business run smarter and more efficiently.

I am a seasoned Java Architect with over 25 years of experience in designing, developing, and maintaining scalable applications. My primary focus is on Liferay Digital Experience Platform (DXP), where I have over 9 years of hands-on experience, leading complex upgrades, customizations, and deployments for high-traffic portals.
In my most recent role, I was the Subject Matter Expert for the modernization of three major Liferay portals, ensuring seamless transitions across multiple versions (6.2 to 7.4), implementing custom SAML solutions, optimizing performance, and enhancing security. I specialize in upgrading legacy systems, integrating APIs (SpringBoot, Oracle Health), and delivering user-friendly, accessible solutions.
Beyond technical skills, I excel at mentoring teams, promoting best practices, and communicating complex ideas clearly to both technical and non-technical stakeholders. Whether you need someone to modernize an outdated codebase, build scalable microservices, or lead a team through a complex migration, I bring the experience and leadership to make it happen.
I would love to discuss how I can help you achieve your project goals.
