I’ve been writing code long enough to remember when BASIC felt like magic and when a “debugger” was mostly your own frustration. Across four decades, tech has changed faster than hairstyles, but I’ve happily kept both up to date. My coding journey, decade by decade: - 1980s: BASIC (my first love ❤️) and a bit of C - when computers were loud, slow, and beautiful - 1990s: Pascal, Cobol, C++ - the era of serious programming and questionable UI design - 2000s: PHP + MySQL - building the early web one spaghetti script at a time - 2010s: Java and JavaScript - enterprise on one side, wild west on the other - 2020s: Node.js, React, Solidity, Python — AI, blockchain, automations, and everything in between Along the way, I realized I don’t just like building software, I like building teams, systems, and processes that actually work. So I spent the last years mixing: - Project & Product Management across IT and SaaS - International Development projects (where "deadline flexibility" is a lifestyle) - Banking & fintech (where deadlines stop being flexible) - Academia, mentoring, research and development And yes… the real mining industry - not crypto mining, actual mining with rocks, helmets, and very serious engineers... Today I’m a hybrid: 🔧 Engineer by instinct 📊 Product/Project Lead by experience 🌍 International collaborator by habit 🤖 Automation & AI enthusiast by passion If it involves solving problems, building something new, or turning chaos into a process - I’m probably interested.

🚀 Senior Full-Stack Developer & Software Engineer with 9+ years of experience building, modernizing, debugging, and maintaining production software. I help businesses turn complex requirements and problematic codebases into reliable, maintainable software — from architecture and development to testing, deployment, debugging, and long-term support. I also work AI-native. I use Claude Code and OpenAI Codex extensively in my daily development workflow to investigate codebases, plan implementations, accelerate development, write and run tests, review changes, debug complex issues, and work effectively across unfamiliar technologies. AI makes development faster. Engineering experience is what makes the result reliable. 💻 WHAT I CAN HELP YOU WITH • Full-stack web application development • JavaScript & TypeScript development • Node.js back-end development and APIs • React / React Native applications • PHP & Python development • AWS and cloud-hosted applications • Docker / Docker Compose environments • SQL & database development • REST APIs and third-party integrations • Electron & cross-platform desktop applications • Legacy application modernization • Complex debugging and bug fixing • Performance and security improvements • Automated testing and production QA • Technical SEO and web performance 🛠️ TECHNOLOGIES JavaScript • TypeScript • Node.js • React • React Native • Electron • PHP • Python • C# • SQL • MySQL • MariaDB • PostgreSQL • MongoDB • AWS • Lambda • S3 • CloudFront • EC2 • Docker • Nginx • Git • GitHub • Jest • PHPUnit • REST APIs • HTML • CSS 🤖 AI-NATIVE DEVELOPMENT Claude Code and Codex are part of my normal engineering workflow — not replacements for engineering judgment. I use agents to move faster across large codebases, investigate problems, prototype solutions, implement features, generate tests, review code, and learn unfamiliar libraries or APIs quickly. Every result still gets the same thing I would expect from manually written production code: review, testing, validation, security awareness, and maintainability. 🏗️ MORE THAN JUST CODING I've worked across the complete software lifecycle. As the founder and developer of my own software business, I've handled product development, architecture, desktop applications, websites, APIs, licensing systems, infrastructure, payments, security, analytics, customer support, and ongoing maintenance. For client projects, I'm comfortable entering an existing or legacy codebase, understanding how it works, identifying the real problem, proposing a solution, implementing it safely, and documenting what changed. I've worked remotely with clients and companies in the USA, Germany, and Austria since 2017. ⭐ WHY CLIENTS HIRE ME • 9+ years of professional development experience • 100% Upwork Job Success • 5.0 Upwork rating • Strong problem-solving and debugging skills • Comfortable with both modern and legacy systems • AI-accelerated development with human engineering oversight • Clear communication and documentation • Production-focused rather than "it works on my machine" • Long-term ownership mentality If you need someone who can understand the problem, work independently, use modern AI tools intelligently, and take responsibility for actually getting the software working in production, let's talk.

I build the email and CRM systems that ecommerce brands run on. Klaviyo, HubSpot, Shopify Plus. Flows that recover revenue, deliverability that keeps you out of spam, and automation that takes manual work off your team. Ten years in CRM, lifecycle marketing and product. I ran email and growth for a DTC brand from launch to multi-million revenue, led CRM at Split Dragon, and managed product teams at Bayt and BRANDED across the Dubai and Paris markets. What I take on: - Klaviyo and HubSpot builds: welcome, abandoned cart, browse abandonment, post-purchase, winback, replenishment - Deliverability repair: SPF, DKIM, DMARC, domain warmup, list hygiene, inbox placement recovery - Shopify Plus integrations: subscriptions, loyalty, reviews, helpdesk, checkout logic - ESP and CRM migrations without losing segmentation or history - HTML email templates that render correctly in Outlook - Automation and AI layers: n8n, API integrations, agent workflows for repetitive marketing operations How I work: I start with the goal and the numbers, not the tool. You get documented systems your team can run without me. No vanity metrics and no dependency. Available for projects and retainers. Based in Belgrade, so I overlap with both US and EU working hours.
