    💡 Rising ad costs are reshaping eCommerce. To stay profitable, it's crucial your website does two things: 1️⃣ Maximises how many people become customers (CVR) 2️⃣ Maximises the amount they spend with you (AOV) So not only do you need a quality technical team on hand, but also one that understands what makes people buy. Here’s what clients had to say about working with us: “"Working with you is like a breath of fresh air"” “I have been in eCommerce for a long time so know when people actually know what they are talking about rather than just trying to 'sell' their services, and these guys actually know what they are talking about.” 📤 Here to chat if you have questions about your Shopify site, or anything else related to scaling your ecomm business. 📞 Let me know if you’d like to schedule a call to discuss your situation in more detail to see if we can help in any way.

    Hi, I am Martin! I am a passionate software engineer with a laser focus on pushing technological boundaries. I specialise in computer vision, 3D graphics and practical AI applications. Whether it’s gathering insights from images and videos through advanced computer vision, deploying intelligent solutions with large language models, or creating breath taking 3D web experiences, I bring creativity and precision to every project. With my experience from Silicon Valley startups, I can jump into a large code base as well as start a green field project with the best practices in mind. I offer both software engineering work on larger projects as well as a simple consultation. Reach out to me about anything related to: - computer vision - machine learning and AI - gaussian splatting or neural radiance fields - large language models - 3D computer graphics, understanding of 3D world - 3D experiences on the web (e.g. with three.js) - general full stack engineering How I work on larger projects: 1. Project request To kick off our collaboration, simply reach out to me with your project request. This gives me a better idea of what you’d like to get done and assess whether I am the right fit. If so, we’ll schedule a call to delve further into details. 2. First Meeting During our first call, we’ll get to know each other and see if we are a good fit together. We’ll talk about your goals and requirements and make sure we are on the same page. We’ll also go through all the clarifying questions and define the next steps for our collaboration. 3. Proposal After I have learned and understood as much as possible about your proposal, I’ll create a custom proposal of our collaboration. In the proposal I will clearly outline the goals, key deliverables, time and cost estimates, all split into incremental milestones. We’ll also have a chance to go back, discuss, and update any part of the proposal. 4. Implementation Once we are on the same page about the milestones and deliverables of the project, I have everything I need to start with the implementation. In this step, communication is the key to success. You can expect clear and timely updates about the progress from me. This way we ensure the project is on the right track. 5. Launch As the last thing, I will hand over all the code I have produced, help you integrate the solution into your existing tech stack, and give you all the necessary instructions and documentation.
