With experience across full-stack development, backend systems, AI integrations, automation, trading platforms, APIs, SaaS products, eCommerce, and complex problem-solving, I help businesses turn ideas into stable, scalable, and production-ready applications. My clients often describe me as someone who does more than just write code. I analyze the real problem, suggest better approaches, improve architecture, and deliver solutions that are easier to maintain and grow. Recent client feedback highlights my strengths: ✓ Built automated trading strategies and indicators that exceeded the initial scope and performed reliably in live environments. ✓ Developed and fixed complex C#/.NET, API, and financial integrations with careful testing and troubleshooting. ✓ Created AI-powered systems, CRM workflows, automation solutions, and backend platforms. ✓ Delivered Shopify, WordPress, and custom web applications with strong attention to UX, performance, and business goals. ✓ Improved existing projects by identifying hidden issues and implementing cleaner, more efficient solutions. My technical expertise includes: • Full-Stack Web Development • PHP, Laravel, Node.js, Python, C#, .NET • React, JavaScript, HTML, CSS • AI Integration & Automation Workflows • API Development & Third-Party Integrations • SaaS Architecture & Database Design • Shopify & eCommerce Solutions • Trading Systems, Indicators & Algorithmic Strategies • Debugging, Optimization & Code Improvement • Cloud, Server, and Deployment Support My working approach: 1. Understand your business goal, not only the technical request. 2. Design a practical solution with long-term scalability in mind. 3. Communicate clearly throughout development. 4. Test carefully and deliver stable results. Whether you need a complete application built from scratch, improvements to an existing system, automation of manual processes, or help solving a difficult technical challenge, I focus on delivering measurable value. I believe great development is not just about completing tasks. It is about creating solutions that help your business move forward. Looking forward to work with you. less -

My approach is simple: understand the real problem first, scope honestly, then build something clean enough to still make sense a year from now. Experience 8+ years across SaaS platforms, e-commerce systems, and AI-integrated web applications. I've built custom CRMs, marketplace platforms, booking and payment systems, and automation pipelines connecting LLMs to real business workflows. Core Stack Frontend: React, Next.js, Vue.js Backend: Node.js, Laravel, Express, Django/Flask where the project calls for it E-commerce/CMS: WordPress, WooCommerce, Shopify, PrestaShop Databases: MySQL, PostgreSQL, MongoDB, Supabase AI/Automation: OpenAI and Anthropic API integration, n8n, LangChain-based agent workflows Payments/Integrations: Stripe, PayPal, Twilio, REST/GraphQL APIs, headless CMS Background Bachelor of Commerce (Marketing) and a BSc in Psychology, which shapes how I think about the projects I build, not just the code, but the user behavior and business logic behind it. Certified in Google Ads Search, Google Analytics, and Microsoft 365 SMB Sales. How I Work Every project starts with real scoping, not a generic quote. If something sits outside my direct experience, I say so upfront and propose a way to bridge it responsibly, whether that's a smaller first milestone to prove capability or an honest caveat before we commit. I'd rather lose a bid on transparency than win one on an inflated claim and disappoint a client six weeks in. What You Get Clean, maintainable code. Realistic timelines. Direct communication throughout, no disappearing between milestones. And a developer who treats "I don't know that platform yet, but here's how I'd approach learning it responsibly" as a legitimate answer, not something to hide. If it's technically achievable, I can build it, and I'll tell you plainly if it isn't. less -

Most of my work lands in one of these: - Scraping and data extraction: pulling data from websites or PDFs, cleaning it up, and handing it back as CSV, Excel, Google Sheets or straight into your database. - Automations and API integrations: connecting the tools you already use (Sheets, Airtable, Notion, CRMs, webhooks, n8n) so the repetitive steps stop eating your day. - Small web apps and internal tools: dashboards, admin panels, calculators, browser games. React/TypeScript on the front, Python or Node on the back. less -
