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'm a front-end developer with 3+ years of experience building responsive, production-ready websites and web applications. My stack is Vue 3, Nuxt, React and Next, with TypeScript and REST API integrations. I've shipped real projects, from animation-driven local business sites to a role-based enterprise SaaS platform used daily by hospitality operators across multiple locations. That SaaS project involved building complex UI systems with dynamic permission-based interfaces, batch actions, third-party API integrations, and working inside a long-lived production codebase alongside backend engineers. I also work with GoHighLevel, building pipelines, automations and funnel pages, though web development is my main focus here. I'm actively building my Upwork reputation.
