    Hello! My name is Meinte and for the past decade I have been Leading, Developing and Conceptualizing solutions for a wide variety of Clients. I have a strong technical background with over 15 years of experience. - Strong foundation in an object orientated approach - Combined with years of experience using functional languages - NodeJS, Express, NestJS, Mongo, Redis, RabbitMQ, Kafka as backend technologies - ReactJS, VueJS and some Svelte as frontend. - But happy not using frameworks too. Hire me to think critically about: - Architecture - Sustainable Code - Long term technical strategy - Application Performance - Well Documented code - Well Tested code My role in projects is usually one which fits my highly technical background. I have specialised myself in comprehensive front-end solutions. But I do enjoy switching it up, and have worked on various backend systems in the past. In fact, I started out as a backend Java developer and have also been involved building scalable solutions using various technologies(elastic beanstalk, rabbitmq, redis, etc.). However, the past two years my main focus has been on building platforms using React on the frontend, and NodeJS on the backend. Often enough, I am not only brought into projects to deal purely with coding, but to get better insight in the nature of the problem and what the right solution would be. Not being tied into a specific technology or platform helps in deciding the correct tool for the job. With years of experience comes an understanding not only from a technical perspective, but from a user experience point of view as well, besides this there's a better understanding for requirements from the client and a good feel for what works in terms of processes and tooling used during the lifecycle of a project. The best use of my time is recognising this experience and working together with me during multiple phases of the project, not in one specific role, but having a wide perspective of the requirements of the project and knowing what it is that is exactly being solved.

    I am a software engineer and I specialize in AI agents, helping businesses implement AI and providing consultancy. I ensure seamless integration with existing systems or I gladly build one from scratch. - Custom AI solutions tailored to your needs - Full end-to-end service, requiring no technical expertise on your part - Custom operating systems for individuals and businesses I also built my own company offering the above mentioned services. I will add a link to my website in the portfolio section. ------------------------------------------------------- Some of the automated solutions I've built: - Automated onboarding and interviewing process – Helped filter the right prospects, streamline hiring, and increase the number of interviews, ensuring a better fit for each role. Also improved the onboarding experience, making the starting phase smoother for new hires. - Automated price reports and proposal generation for real estate – Saved time and improved pricing accuracy by factoring in multiple variables dynamically, leading to more reliable outcomes. - Automated maintenance task scheduler – Users can report issues via text, WhatsApp, email, phone, or other channels. The system automatically categorizes them by urgency, organizes them in a clear overview, and schedules them appropriately. The responsible parties are then notified with all relevant details. This automation eliminates the entire back-office process, removing the need for endless back-and-forth messaging.

    I have more than 10 years of experience in Full Stack Engineering and DevOps Engineering, encompassing projects in cloud systems, web applications, and automation. My current main area of interest is within large data-driven applications in a distributed, scalable, cloud environment. I have many years of experience in writing data scrapers for online data mining applications (with experience automating scraping data from thousands of sites). While my preferred technologies include Python, Django, Flask, Go, Gin-gonic, AWS, Elasticsearch, and Terraform, I am also experienced in Javascript, Google Cloud Platform, React, Vue, CloudFormation, and many more technology options. DEVOPS / AUTOMATION With most of my projects, I am responsible for everything from ground up. This, of course, includes the code of the application, but also the automated pipelines, automated deployments, version control, and Infrastructure-as-Code. I have vast experience with designing and developing system architectures in Google Cloud and Amazon Web Services. I have used many available DevOps tools in these projects, with my favorites consisting of Terraform, CloudFormation, Gitlab, Github, Jenkins, Ansible, Docker, Packer, AWS Code Services, TravisCI, and CircleCI. Whether you need to migrate data, design infrastructure, or automate pipelines and deployments, I have the experience and expertise to help. WEB BACKGROUND I have wide knowledge of many modern technologies in the web development stack -- from low-level networking protocols and system tweaking (debian, nginx) to server-side programming (Python) to client-side programming (HTML5 APIs, Javascript, React.js, Vue) to many NoSQL and SQL data providers (Elasticsearch, RDBMS, MongoDB, Redis, DynamoDB, etc). I could solve the programming task of any complexity for you. I prefer developing complex and unique web services and/or user interfaces rather than creating simple websites which are similar to each other.
