I design and build iOS apps and websites, handling both the design and the code so your project stays in one pair of hands from the first sketch to launch. Most freelancers do one or the other. I do both, which means no messy handoffs and a product that looks great and actually works the way it should. I care about the small details that make an app or site feel premium: clean layouts, smooth interactions, and interfaces that are genuinely easy to use. What I can help you with: iOS apps Native app design and development in Swift and SwiftUI App interfaces, onboarding flows, and App Store submission Firebase integration for login and data UI and UX design App and product design, from wireframes to polished high-fidelity screens Interactive prototypes in Figma Web Responsive websites and landing pages built in React Design and development, from concept to a live site I communicate clearly, hit deadlines, and treat your project like it is my own. If you want one person who can take your idea from concept to a finished, polished product, send me a message and tell me what you are building.

I build tools that actually get used. Most of the apps in my portfolio started because I needed them myself. A gym tracker built around my own training split. A stock dashboard for managing physical product inventory. A focus timer that works in the background without breaking. I build these things because I hate bloated solutions that solve 80% of the problem. That same approach is what I bring to client work. I've built a real estate showcase site for a luxury property brand in Turkey, a stock management system for a supermarket in Denmark, and a full AI-powered SMS platform handling automated lead conversations with Twilio and OpenAI. The stack I work in is React, Node.js, vanilla JS, and I deploy on Railway or Vercel. I connect AI APIs when the project needs it and skip them when it doesn't. What I'm good at: scoping fast, building clean, and not disappearing mid-project. I work with founders and small business owners who need a specific tool built, not a generic template with their logo slapped on it. If you know what you need built, message me and we'll figure out in 10 minutes whether I'm the right fit.

I build AI systems that actually work in production. As co-founder and CTO of a SaaS company, I designed and shipped a multi-agent platform that runs live customer interactions every day: 20+ AI agents on LangGraph/LangChain and the OpenAI Responses API, with an eval framework, prompt-injection safeguards, RAG (pgvector), and MCP integrations. I built it from scratch and run it end-to-end, from architecture to deployment. What I do best: - AI agents & LLM applications: multi-agent systems, chatbots, RAG pipelines, tool calling, MCP - Evaluation & reliability: eval frameworks, guardrails, automated testing — making AI dependable - Full-stack delivery: Python/Django, TypeScript/React, C#/.NET, PostgreSQL, Azure, everything-as-code I bring 15+ years of software engineering experience, including years in a security- and compliance-heavy enterprise environment (pensions/finance). So you get someone who moves fast AND builds solid foundations: clean architecture first, one feature done well over five half-finished. I work end-to-end. I can scope your idea, architect it, build it, ship it, and explain it in plain language along the way. Clear communication, no surprises, and I finish what I start. Fluent in English, based in the Netherlands, available ~32 hours/week.

Hi, I’m Dima, a web and software developer passionate about building functional backend-driven applications like admin dashboards and web apps. Though skilled in both frontend and backend, I prefer projects with real logic—not just landing pages. I studied software development and started coding out of curiosity for the digital world. I blend code and no-code tools to work faster and smarter, integrating AI and strong marketing design to boost results.

I help Shopify store owners find and fix the hidden issues killing their conversions. Before I quote you a price, I audit your store and show you exactly what's broken — most stores I look at have 5-10 critical problems that are invisible to the owner but obvious to a developer. What I do: - Shopify store optimization (speed, SEO, mobile, checkout flow) - Full Shopify store builds and migrations - Custom Shopify app development (Liquid, React, Node.js) - Conversion rate optimization and A/B testing - Ongoing store management and monthly audits My stack: Shopify Liquid, Next.js, TypeScript, Tailwind CSS, Supabase, Vercel. Registered Shopify Partner. I also built and run a 15,000+ product discovery platform from scratch, so I understand ecommerce from both the dev and the merchant side. Based in the Netherlands. I work fast, communicate clearly, and deliver on time. Happy to do a free 15-minute intro call before any project to make sure we're a good fit.
