👋 Hey, I'm Trevor, a webapp and automation developer based in the Netherlands. I build the backend systems that run your business while you focus on growth: lead pipelines, AI agents, SaaS integrations, and operational workflows that actually hold up. Here's what I've shipped for clients: → For a B2B company in the wifi/networking space, I built and managed a 45-inbox cold outreach system that sent 44,000 emails, generated 429 real replies, and created 126 sales opportunities worth $126K+ in pipeline value. → For a Dutch e-commerce brand, I built a Google Maps scraping pipeline using n8n and Apify that delivered 2,000+ verified, enriched leads, fully automated from search to CRM. ⚙️ What I build: → AI agents and chatbots that handle customer support, lead qualification, and outreach automatically → Lead generation pipelines that find, enrich, and contact your ideal clients without manual work → SaaS integrations that connect your tools and keep data flowing across your entire stack → Operational workflows that replace the repetitive tasks eating up your team's time 🛠️ What I work with: n8n · Make · Claude API · OpenAI · Apify · Airtable · Instantly · Google Sheets · Supabase · Pinecone · Webhooks · REST APIs If it has an API, I can connect it. If you need clean logic, reliable builds, and someone who treats your systems like they matter, let's talk.

Senior front-end and mobile developer with 10+ years of experience building high-performance React, React Native, and Flutter apps across industries such as fintech and medical. I’ve been extensively working with Flutter since 2020, and have deep experience with its surrounding ecosystem, such as BloC, Riverpod and Flutterfire. I also have experience in backend development, using Node.js and Firebase to build performant and scalable APIs and cloud-based backend systems. Additionally, I've been working with AI and Machine Learning since early 2018, and have expertise in training and deploying TensorFlow models on mobile devices. Finally, I'm a passionate advocate for Scrum and Agile, and have successfully coached teams to leverage these methodologies to achieve remarkable results. I'm fluent in Dutch, English, and Russian.

Introducing a Passionate Developer: I love developing and solving problems, if you're looking for a reliable programmer that won't give up on solving issue's I'm the one you're looking for. Experienced in many programming languages and expert with Python, Javascript, C#. Knowledgeable with frameworks like React.js, Node.js, .Net, .Net core, Django, Flask.

I help integrate AI capabilities into real web applications and product workflows. I work with React, Next.js and FastAPI to connect modern interfaces with AI services such as OpenAI and external systems through APIs and automation workflows. My work typically focuses on building applications where user input, AI processing and automated actions are part of the same system. This can include qualification systems, product discovery interfaces, AI-assisted content workflows, or integrations with external platforms such as CRM systems and other APIs. I enjoy working on projects where frontend interfaces, backend logic and AI capabilities come together in a coherent and practical application.

I am a Fullstack Developer with a deep backend foundation and a Product Owner mindset. I don't just close tickets, I build systems that bridge the gap between complex business logic and scalable, production-ready infrastructure. I thrive in environments where I can take full ownership of a product, from the database schema to the final pixel. Why I Bring Value to Your Team: Engineering 2.0 & AI-First: I specialize in modern development workflows, leveraging AI tools to orchestrate agents and automate development cycles. This allows me to build with significantly higher architectural precision and speed. Business-to-Product Logic: I excel at translating vision into technical reality. My recent success involved architecting a complete B2B/B2C ecosystem for a Dutch rental vendor, where I identified user pain points and stakeholder interaction schemes before they could become bottlenecks. Robust Technical Stack: Backend: Java (Spring), Node.js (TypeScript). Frontend: React.js. Data & Infrastructure: PostgreSQL, MongoDB, Prisma, Supabase, Redis. Scalable Architecture: Expert in SOLID principles and clean architecture. Currently focused on implementing reactive patterns and high-concurrency solutions using Kafka to ensure systems are ready for rapid growth. DevOps & Observability: Proven experience in managing cloud-ready deployments via Docker, K8s, and GitHub Actions, with a focus on full-stack monitoring using Grafana. Beyond the Code: I am an entrepreneur at heart, currently developing my own product. This gives me a unique perspective on ownership and responsibility - I identify "leaks" in business processes and use technology to plug them. I am ready to bring this blend of high-level architecture and AI-driven efficiency to your project. Let’s discuss how I can help you scale.

I’m a full-stack .NET developer with over 10 years of experience building web, desktop, and cloud applications. I work mostly with C#, ASP.NET Core, Web APIs, and Azure services. Over the years, I’ve developed systems ranging from microservice-based blockchain platforms to CRM desktop apps and high-performance web solutions. I care about writing clean, maintainable code and using solid architecture to make projects reliable, scalable, and easy to extend. If you need someone who can take a project from idea to a finished product with attention to detail and a practical approach, I’d be glad to help.

I build premium responsive websites and e-commerce experiences for brands that want to look modern, trustworthy and memorable. I am based in the Netherlands and currently developing my own fashion e-commerce business project called NO TIME — a premium brand concept with product sections, cart, checkout flow, size selection, image preview, smooth animations, Instagram integration and strong visual identity. My focus is not just writing code. I help turn an idea into a complete digital product with clean design, strong brand presentation and a smooth user experience. I can help with: • premium business websites • fashion and lifestyle e-commerce websites • landing pages for brands and startups • responsive frontend development • cart and checkout UI • website redesign and visual upgrade • product pages and product cards • modern HTML, CSS, JavaScript and React interfaces I work carefully, communicate clearly, and focus on making websites that look professional on both desktop and mobile. If you need a website that feels modern, clean and ready for real customers, I can help build it.

I build the layer between your systems and your insight. Most technical environments are messier than they need to be — sensors that log to nowhere, systems that can't talk to each other, data that exists but doesn't inform anything. I untangle that. My work combines systems integration, IoT and digital twins, and end-to-end development. I design and build integration layers, real-time data flows, and digital twins — and when there's a product idea worth pursuing, I take it from concept to working system. That includes LLM-powered agents: I've built a real-time AI commentary agent on live sensor data and an automated job-scoring pipeline that evaluates and routes opportunities via Telegram — both running on my own infrastructure. Stack includes Python, FastAPI, Node.js, React, Next.js, PostgreSQL, InfluxDB, DuckDB, Node-RED, LoRaWAN, ChirpStack, Grafana, and REST APIs. Available for projects, consultancy and partnerships.
