    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.

    I'm a Software QA Tester! I solve problems you don't know you have. I would like to consider myself a perfectionist - someone that likes to look at the nitty-gritty details which most people would tend to avoid and question, which may perhaps be seen as both a pro and a con; because being able to balance creating a great software with delivering it on time takes a lot of understanding. So I believe having a perspective of not just a tester but as well as a developer gives me that extra edge in breaking the system and avoid having any defects or bugs down the line. In addition to that having an end user perspective is equally important to ensure all the requirements are met and 100% acceptance testing is in place! I believe to save precious time and resources it’s also important to test early as much as you can as opposed to building the whole system or feature and then testing it. To sum it all up communication is critical and paramount in executing accurate requirements and getting the job done free of any bugs – this is where I and my team come in! • Proficient in both manual and automated testing • Day to day communication at every step of the way • Full transparency between the stakeholders, PM, developers, QA and the rest of the involved component team members • Expertise in Regression, Functional, System, Integration, Web Services, and Web & Desktop applications. • Ability to manage and perform QA/QC process. • Ability to meet strict deadlines while retaining quality standards • Strong analytical skills to handle multiple tasks. • Excellent at quickly identifying high-level test strategies and problems • Collaborative but decisive personal style, effective communicator, and problem solver • Ability to quickly master new software and apply its full range of Capabilities. • Proven ability to set priorities, identify issues, and drive issues to acceptable resolution in a timely manner. Technical Skills: • TDD, BDD, Gherkin, Acceptance testing, Integration testing, Functional testing, and others • Project management, bug tracking and other issues with Jira • QA Automation with cucumber framework • Programming languages with Ruby, Python, Java, JavaScript • Web application automation with Selenium Webdriver

    Profile I am a solution-focused software test engineer with over 10 years of commercial experience, looking for a reputed company which will help me further develop my abilities and skills in the field of testing. Some of my recent achievements are: Being involved in end-to-end testing of most of the projects that included over 50 different client specific software structures. Some of the more complex ones would include testing from the frontend to the backend, including the database and a third-party data structure migration/integration. Experience with recruiting and embedding new people into the team, training and onboarding them into my testing team. Being responsible for creating an automated test case suite for all API based projects using Postman. Also created a fully automated suite that would test all data migration software. A simple mistake in data mapping would ruin the end result, and with this automated tool, we removed all development issues.
