01 About

I'm a full-⁠stack developer with 3 years of commercial experience in TypeScript. I work mainly on backends and cloud infrastructure with Node.js, NestJS, PostgreSQL and AWS, and I build frontends in React and Next.js.

I've built SaaS products for international clients, from IoT and cybersecurity platforms to migrations of large systems to a new architecture without interrupting their users.

Since 2026 I've been building Reduko as a co-⁠founder: a platform for private tutors, where I'm responsible for the architecture, backend and infrastructure.

Reduko

A platform for private tutors to run lessons, homework, materials and payments in one place: single and recurring lessons written to Google Calendar with Meet links, a shared whiteboard that teacher and student draw on live, a file library, announcements and chat.

03 Experience

    Node.js Developer · The Software House

    I work on the backend of a platform used by brokers, which we are moving from a legacy system to a new set of services without interrupting the people who rely on it every day.

    • NestJS services for the new platform and the migration path that keeps the legacy system in sync while brokers move over.
    • Before the broker platform: the company's internal app for managing projects and people, across the React frontend and the Express backend.

    Fullstack Software Engineer · Devopsbay

    Worked with one of the largest headless CMS platforms on moving a service out of a Ruby monolith into an event-⁠driven architecture on AWS Lambda.

    • New APIs and SNS consumers that connect the service with the rest of the platform.
    • Old and new implementations running side by side, so traffic could move over gradually and safely.

    Software Developer · Gorrion

    Started as a frontend intern and grew into a full-⁠stack role, building SaaS products for international clients from the first features through to production.

    • IoT water-⁠monitoring platform: features delivered end to end across NestJS, GraphQL and Next.js, including usage analytics and PDF and Excel reports.
    • Generative AI R&D on Amazon SageMaker and Bedrock, including moving the company's internal Slack chatbot to Bedrock, shared with the team through internal workshops.
    • Cybersecurity platform for small businesses: integrations with backup, endpoint protection and monitoring tools on AWS Lambda and SQS, and a multi-⁠region setup that keeps customer data in its region.
    • Online memorial service: React and TypeScript frontend work inside the client's own English-⁠speaking team.
    • College planning platform for students in the US: frontend features in Next.js with tRPC and Prisma.

    IT support · Fizjofit

    Math tutor · Self-⁠employed

    Taught math one on one to about 36 primary and secondary school students over almost seven years and prepared them for the eighth-⁠grade exam and the matura.

    • Seeing how much of a tutor's week goes into scheduling, homework and payments is what led to Reduko.
