ABOUTME
I am a Senior Full-Stack Software Engineer with a focus on AI, bringing over five years of experience across frontend (React, TypeScript) and backend (Python, Node.js, Fastify, MongoDB and PostgreSQL), with an emphasis on AI-powered applications leveraging LLM APIs. I adapt quickly to new technologies and tools, believing that mindset is what truly matters. With a proactive "get it done" approach, I solve challenges with persistence and a willing to learn.
In my free time, I build AI-driven personal projects, including Comprehend AI, an LLM-based language learning app. Alongside career related activities, I try to live an active lifestyle by lifting weights and climbing.

WORKEXPERIENCE
Founding Engineer
Part of a small early stage team developing Clair's v1 product from the ground up, delivering the core experience that enabled us to sign and service our first customers. I own end-to-end frontend development and UI/UX, taking the product from initial Figma wire-frames to a live, production-grade platform built with React. Additionally, I contribute to our backend services, implementing FastAPI endpoints and developing ML pipelines using Python.

Senior Software Engineer
As part of a newly formed team, I helped build and launch Wolt’s self-service merchant onboarding platform, enabling merchants to sign up, verify, upload menus, set commission rates, and sign contracts without manual support. Took ownership of the frontend development and UI/UX, collaborating closely with backend engineers, designers, and product leads. Our solution integrated third-party services like Signicat and Juro, supported multiple locales, and scaled to several countries.
Full Stack Developer
As part of a cross-functional team, I developed core, platform-agnostic features for Smartly.io’s main application, including a notification system, user access controls, and SSO authentication. My work improved scalability and user experience, enabling seamless access and collaboration across the platform.
Software Engineer Intern
My role involved helping with designing and developing web mockups, using the Typescript framework Angular 7 and the Angular material component library.
PEERFEEDBACK
Youssef was my direct report in one of my teams at Wolt, and I had the pleasure of working with him for about two years. He's a quick, solid executor—give him a task, and you can trust that he'll get it done efficiently and with high quality. His React and TypeScript skills are strong, and he takes a methodical approach to his work, making sure things are built to last. Youssef's presence stands out. He's extroverted, always up for a good conversation, and if you ever need someone to put together a demo or a product announcement, he's your guy. He knows ...
Diego Casillas
Engineering Team Lead at Wolt
Youssef joined Clair to help take our product from 0 to 1. He contributed significantly to the early shape and form of our product, handling not only most of the front-end development work but also the design of our early UI. Youssef is a great communicator who is eager to learn new skills and adopt the latest tools to accelerate his work. I warmly recommend Youssef as a valuable member of any strong product team.
Eerika Savolainen
Co-founder & CEO at Clair
We worked together for over a year on a high-visibility project. Despite the high pressure and challenges of the project, Youssef always showed a strong willingness to take feedback from the product manager and designer, and his ability to adapt to changes ensured the team stayed aligned and focused. His dedication to executing work effectively contributed to the team’s ability to launch the product successfully and achieve meaningful outcomes.
Xiaoyu Ji
Senior Product Designer at Wolt
I've been a team lead for Youssef at Smartly for about a year. During this time Youssef has proved to be an extremely fast learner and quickly became an important part of the team. Youssef was able to deep dive into the assigned context, independently figure out the amount of work and carry it out. Great level of participation in team's process, always ready to discuss how to improve it. Youssef is also keen on both giving and receiving feedback. I can recommend him joining any team to further elevate the team's culture and as an individual contributor ...
Ilia Bazanov
Senior Software Engineer
During my initial learning phase of my software engineering career, Youssef was my mentor as he gave me pointers on what to learn and helped me with any blockers that I might have faced. Youssef has demonstrated his ability to teach what he himself has learned in a clear and understandable way. The knowledge gained was successfully applied into my job search and eventually helped me find my first engineering job in Finland as a frontend developer at Wolt.
