Hey! 👋 I’m Georgy, a Founding Creative Developer at nklnk.com. I develop, design, and optimize bespoke websites, e-commerce stores, and web apps that are clean, modern, and easy to scale and maintain. I combine my experience in design and coding with platforms like Webflow, Wized, and Shopify and cutting edge AI, to prototype > design > develop > test > deliver projects of all styles and complexities. Have something in mind? Get in touch! 🕊️ I’ve worked with both new and established businesses, helping startups get discovered and assisting existing brands in revamping their online presence for better performance and engagement. My past work includes launching e-commerce stores, developing marketing websites to drive traffic, and building complex platforms like property booking, membership, and video hosting sites to streamline operations and enhance user experience. My key strength? Attention to detail and the understanding that “low code” doesn’t mean “no code.” I have a deep technical knowledge of web development, including how each low-code tool works, what its limitations are, and how to push beyond them with custom code and best practices. Here’s how my typical project goes: ❇️ Briefing & Research – We discuss the brief, find references, and pick the tech stack. ❇️ Design (Figma) – For simple projects, this step can be done directly in Webflow. ❇️ M̶a̶g̶i̶c̶ Development ❇️ Revisions - async & collaborative communication via Markup, Slack, Loom ❇️ QA - testing on Windows, macOS, Android and iOS. ❇️ Final Steps – Google Console, domain setup, analytics, etc. ❇️ Delivery – Project handover, training calls and teaching materials. Please check out my past projects and glowing client testimonials below and if you have a project in mind, please get in touch (by clicking on the "..." and then selecting "Send a message"). Cheers, Georgy

I specialize in bridging the gap between education and technology as an AI & Programming Trainer with over six years of experience in software development and AI systems. My expertise includes C and Java programming, coupled with a solid foundation in web technologies and databases. I have successfully developed impactful applications, including a facial recognition system for real-time attendance tracking and a comprehensive healthcare integration platform that streamlines patient data across facilities. My ability to mentor students and deliver high-quality solutions has been recognized throughout my career. If you seek a skilled developer who can think creatively, execute effectively, and foster learning, let's connect to explore how I can contribute to your project or team.

I build AI-powered automations and data pipelines that do the repetitive work, then I personally verify every deliverable before it reaches you. AI does the heavy lifting on my side. I stay accountable for accuracy, structure, and fitness for purpose. What I build: - RAG systems and Claude/GPT integrations (chat over your documents, knowledge bases, Q&A tools) - Data extraction and ETL pipelines (pull data from websites, APIs, PDFs, or government sources into clean, structured output) - Workflow automation (Python scripts, API integrations, Airtable systems, scheduled jobs) - Document and report generation pipelines (turn raw data into formatted deliverables automatically) Proof I ship: I built ReadbackAI, an FAA test prep app running retrieval augmented generation on Claude with a Flask backend and iOS client, and SamBOT, an automated pipeline that extracts and analyzes federal contract data from SAM.gov daily. Why the QA promise is credible: I spent 20 years in Navy Medicine, retiring as a Commander. I directed IT and operations across 50+ facilities in 12 countries and led a regional deployment of a $4.3B electronic health record program with zero downtime. I know what accountable delivery looks like when errors are not an option. How I like to work: fixed-price, clearly scoped deliverables. You describe the outcome, I define the scope and price, you get a working result with documentation. If your project prohibits AI-assisted work, I am not the right fit and will tell you so upfront.

Fractional CTO and software architect with 25+ years of hands-on engineering experience. I help founders, startups, and growing companies make better technical decisions, build stronger engineering systems, and scale products with less risk. For the last 5 years, I have been building Growity Systems as CTO and co-founder, leading architecture, product development, and engineering execution end-to-end. This experience strengthened not only my technical depth, but also my ability to make pragmatic decisions about scalability, delivery, product trade-offs, team structure, and business impact. I work with companies that need senior technical leadership without hiring a full-time CTO. My role typically includes defining architecture, improving delivery discipline, raising engineering quality and technical standards, and helping teams execute with more clarity and consistency. My background combines executive-level technical leadership with deep hands-on development. I am most useful when a company needs someone who can move between business goals, product priorities, system architecture, and implementation details without losing speed or quality. I can help with: • technical strategy and architecture • product-to-engineering translation • system design for scalable and high-load platforms • team leadership and engineering process improvement • codebase review, refactoring, and modernization • hiring, team structuring, and technical due diligence • stabilizing and restructuring troubled projects My strongest domains include fintech, trading infrastructure, digital asset systems, and high-performance backend platforms. I have worked on low-latency systems, exchange integrations, market-data processing, trading platforms, distributed services, and complex backend architectures. I am also actively integrating AI into engineering and business workflows, including autonomous AI agents for code review, research, internal automation, and decision support. I approach AI pragmatically: as a tool for improving delivery speed, engineering quality, and operational efficiency. Clients typically bring me in when they need a fractional CTO to lead the technical side of the business, a senior architect to design or stabilize a critical system, or a hands-on technical leader to bring structure, direction, and execution to a growing team. If you need a senior technical leader who can combine strategy, architecture, delivery, and hands-on execution, I can help as a fractional CTO or software architect.
