About Me

About Me

Hi, my name is Simon. I'm mainly Javascript / Typescript (Node.js) Backend Developer and NestJS enthusiast, with some frontend and devops skills. I love creating solutions using these technologies.

I took part in a few hackathons. I created many commercial projects, for example P.A.B.L.O (solo on backend) and I'm Squad Leader for Fortune 500 company Data Analysis IaaS platform.

Experience

Node.js Developer & Squad Leader

Cloudfide | Full-time | January 2025 - now

As a squad leader and backend developer, I was responsible for delivering, architecting, and maintaining a microservice powering an Infrastructure-as-a-Service platform for Fortune 500 Company Data Analytics Platform. I built this service — and a new product within the platform — entirely from scratch, overseeing every stage from initial design to production deployment.

The system integrates with multiple cloud and enterprise providers, including Azure (resource discovery and management), ServiceNow, Databricks APIs, Microsoft Graph, as well as several internal microservices. I worked with Node.js, Express, RabbitMQ, MongoDB, Kubernetes, Azure, KrakenD API Gateway, and OpenAPI. For background workflows, I leveraged Temporal, designing reliable long-running processes and orchestrations that significantly improved robustness and operational visibility.

Beyond hands-on development, I owned the delivery pipeline and guided the team through the full engineering lifecycle. This included feature analysis and planning, architectural decision-making (independently and with solution architects), code reviews, and defining development standards. I collaborated directly with clients and stakeholders to refine requirements, ensured alignment across teams, and handled onboarding and mentorship of new developers. Additionally, I coordinated with other squads to achieve seamless cross-service integration and platform stability.

NestJS (Node.js) Developer

Dev And Deliver | Full-time | December 2023 - December 2024

As a core member of the backend team I contributed to every phase of development, from task planning and hands-on coding with NestJS to testing and code reviews. I implemented GraphQL for efficient data fetching, developed Retrieval-Augmented Generation (RAG) systems involving AI and vector stores, and created proof of concepts for innovative solutions. I worked closely with the frontend team and client directly to ensure seamless integration and maintained direct communication with the client to align project goals.

NestJS (Node.js) Developer

i3p Sp. z o.o. | Contract - Part-time | October 2020 - December 2023

As lead or solo developer (depends on project). I've gained extensive experience. I've builded applications from proof of concept like, via custom systems integrations to enterprise level systems. It extends from planning the application by client requirements, planning solution and architecture, development, tests, deploys and providing documentation. Specifically, I have leveraged technologies like Node.js, Express.js and NestJS during the development process.
