A Shopify store can have a great product and still lose customers when the website is difficult to use, slow, poorly structured, or limited by its theme. That’s where I come in. I’m a Shopify developer focused on building and customizing stores that look good, work properly, and are easy for clients to manage after the project is finished. WHAT I BUILD Shopify Development I work with Shopify 2.0, Liquid, HTML, CSS, and JavaScript to customize themes and build functionality around your specific requirements. * Custom Shopify theme development and customization * Shopify 2.0 sections and templates * Custom product and collection pages * Custom sections with editable theme settings * Liquid development * Metafields and dynamic content * Shopify app integrations * Custom JavaScript functionality * Shopify store redesigns * Responsive desktop and mobile development Figma to Shopify If you already have a Figma design, I can turn it into a responsive Shopify experience while keeping the layout, spacing, typography, interactions, and overall design consistent with the original design. My UI/UX background also helps me understand how the design should work - not just how it should look. Store Improvements & Maintenance I can also help with existing Shopify stores that need: * Theme updates and customization * Product and collection page improvements * Front-end fixes * Responsive layout fixes * Performance improvements * Theme and functionality troubleshooting * Ongoing Shopify maintenance HOW I WORK For custom Shopify work, I prefer building reusable sections and templates with proper theme settings rather than hardcoding everything. This gives you more control over the store and makes it easier to update content later without needing a developer for every small change. Before starting development, I look at the existing theme, understand what you need to achieve, and determine the most practical way to implement it within your Shopify setup. WHO I WORK BEST WITH I’m a good fit for businesses that: * Need a Shopify store built or redesigned * Want custom product or collection templates * Have a Figma design that needs to be developed in Shopify * Need functionality beyond standard theme options * Want a more responsive and user-friendly storefront * Need help maintaining or improving an existing Shopify store LET'S TALK If you already have a Shopify store, send me the URL and tell me what you want to change. I can review the current setup, understand the requirements, and let you know how I would approach the work.

Do you suspect assets are being hidden? Has your organization been digitally compromised? I am a specialized forensic analyst located in Dallas, Texas, focusing on Blockchain Tracing and Open Source Intelligence (OSINT). Unlike generalist investigators who rely on public databases, I utilize custom Python-based reconnaissance tools to uncover the "Digital Footprint" that suspects think they deleted. My Core Capabilities: * Cryptocurrency Tracing: Tracking Bitcoin, Ethereum, and Stablecoin movements across exchanges (Binance, Coinbase) and "Mixers." * Deep OSINT & Social Engineering: Locating hidden social media accounts (Sherlock), burner emails (Holehe), and leaked credentials on the Dark Web. * Corporate Due Diligence: Auditing companies for "Red Flags," shell entities, and executive vulnerabilities. * Cyber-Security Consulting: Preventing SIM-Swaps, securing 2FA protocols, and hardening corporate infrastructure. Who I Work With: * Private Investigators needing a "Cyber Arm" for complex fraud cases. * Legal Counsel requiring technical evidence for litigation. * Corporate Executives needing discretion and high-level asset protection. Why Hire Me: I combine "Street Smarts" (Language & Intelligence background) with "Code Smarts" (Python Automations). I don't just give you a list of links; I give you a verifiable Intelligence Dossier ready for your client or court. Languages: English, Russian, Uzbek (CIS Region Specialist). Let's find the truth.

Since 2020, I've been building software and writing about it. I've written technical content and thought leadership for an audience of millions. I also maintain small publications covering tech, software development, AI, philosophy and faith. I give projects a distinct voice while building SEO authority. I am not a maintenance programmer. I build framework agnostic systems. I turn ideas into tangible products. I specialize in web data extraction and agentic AI. While I have a strong background in cryptocurrency, I do not take on hype projects and token launches. I build things with meaning. I help teams establish brand authority and I can harvest data from nearly any source on the web. I am deeply interested in how technology has reshaped the human experience. I've witnessed a lot of these changes from a place that many people never get to see and I love to write about it. Take a look at what some of my other clients have said. If you need meaningful insight, feel free to book a consultation.

I am a Computer Scientist & Quant Developer (6+ years) specializing in AI-powered applications, intelligent agents, and algorithmic trading systems. I help traders, businesses, and startups turn ideas into profitable, automated, and scalable solutions. Since 2017, I’ve traded stocks, crypto, forex, and options—using both manual analysis and the custom bots & AI models I build. This blend of trading expertise and AI engineering means I don’t just deliver code—I build systems that solve real-world problems and perform in live environments. 💡 What I deliver: Algorithmic Trading & Quant Systems → Forex, Stocks, Crypto, Futures, Options AI-Powered Agents & Chatbots → Custom GPT-powered assistants, automation tools, RAG pipelines Backtesting & Strategy Optimization → Walk-forward testing, feature engineering, performance tuning Machine Learning & Predictive Models → Forecasting, risk modeling, anomaly detection Full-Stack Development → Django/FastAPI apps, APIs, dashboards, data pipelines 🛠 Tech Stack & Tools: Python, Pandas, NumPy, Scikit-learn, PyTorch, LangChain, OpenAI API, Llama 3, Backtrader, Vectorbt, MT4/MT5, FastAPI, Django If you need someone who can bridge the gap between advanced AI and practical deployment—whether that’s a chatbot, AI agent, or trading bot—I can help you build it.

I left Upwork in 2019 to build products full-time. Four and a half years as a senior engineer at Fitted, then Lead Software Engineer at Hashbranch, where I led marketplace builds for a Bitcoin mining investment platform. I'm back — and the work history below undersells what I do now. What I build: platforms where money and trust are on the line. At Hashbranch that meant the marketplace connecting investors to mining hardware and hosting capacity, including the Buy & Host package flow. When the numbers are someone's investment return, "mostly working" isn't a state you get to ship. At Fitted, I cut average response time from 200ms to 120ms, took 30% off legacy infrastructure costs, and architected the microservices that let the product scale. Those systems ran for years with real users on them. Before that, three of my Upwork contracts ran five years each. One client reviewed my code and then extended it himself. That's the bar — if you can't maintain what I hand you, I didn't finish the job. On AI: my CS degree from UC Irvine specialized in AI and ML, and I build LLM automation now — agentic pipelines that score and filter real data, with a human in the loop wherever the model shouldn't be trusted alone. If you have an AI prototype that demos beautifully and falls over the moment it meets production traffic, that's the work I want most. How I work: I'll tell you if your project is infeasible, or if you're overbuilding, before you pay me to find out. One client hired me purely to assess whether an API integration was viable — the honest assessment was the deliverable. Stack: React, Next.js, TypeScript, Node/NestJS, Python, PostgreSQL, MongoDB, Redis, AWS/GCP, Terraform. Comfortable taking ownership of a codebase someone else wrote. Tell me what's broken or what you're trying to ship, and I'll give you a straight answer on whether I'm the right person for it.
