OpenAshram is an online Yoga courses platform, leading the old tradition of yoga into the modern age of a sustainable, mindful and attentive
attitude towards life. We can meet at any time and from anywhere in our limitless, virtual yoga room.

As a software architect and full stack developer in OpenAshram my primary objective was to renew its product architecture from a Javascript
based API to a modern, TypeScript and NestJS based one, backed with a complete atomic and isolated testing environment. I’ve also developed
OAuth/OIDC authentication and authorization features based on Keycloak, integrated payment flows with PayPal and Stripe, implemented
frontend user access and checkout flows in React, enhanced CI/CD processes based on Docker and Gitlab and designed product specs, user
journeys and test plans. As with other projects, I have also provided mentoring and consultancy in and beyond the tech scope and helped the team and stakeholders reach sound strategic product decisions.

DasLab is making patients healthier by providing universal access to high quality diagnostics. Daslab’s interoperability platform removes these
obstacles enabling healthcare professionals, patients, and laboratories to connect easily and consistently. Its platform - built on the FHIR data
standard - makes it simple for providers and laboratories to offer at-home or professionally sampled medical diagnostics.

My main role in DasLab was a technical product owner and senior backend engineer, owning, architecting and implementing the authorization and
authentication solutions of the DasLab services ecosystem, building a complete OAuth integration with the popular Auth0 provider as a part of an MVP launch of two B2B and B2C products, serving both users and machine clients. I took part and led important tech decisions, provided
management and teams with valuable feedback and pushed processes further to achieve a deliverable MVP against a tight deadline. Alongside
that, I consulted, architected and implemented on various other backend tasks.

I’ve tightly worked with the product manager and other product owners, the backend and frontend teams, consulted management and
stakeholders, created and managed auth product backlog, researched on authentication and authorization solutions, gained a broad experience
with Auth0 services and in product ownership. The solution has been going through penetration testing by external security experts and received high grades.

Cambrium is an innovation leading platform of vegan protein materials. We are leveraging the power of biotechnology to design and develop
cutting-edge materials for a greener tomorrow. We enable new biomaterials in cosmetics, fashion and plastics by harnessing nature's building blocks. We have built a platform based on an automated laboratory, machine learning and synthetic biology to design and develop novel protein materials with enhanced chemical and physical properties.

As a software consultant at Cambrium I have engineered a React based IDE (Single-Page Application) that enables the coding, compilation and
rendering of bio materials. I have worked closely with the product owner who provided the domain expertise. As a developer I provided efficient
frontend solutions and implementation of the app’s spec, for instance code syntax highlighting, material generation from backend and 3D NGL
model rendering.

Remi makes remote work more human and connected. Remi was founded on the realization that culture is an unsolved problem in remote and distributed teams. It's also the key reason many companies don't agree to a remote setup, even if their employees demand it. Remi believes that remote teams should feel confident about building culture remotely.

As a software consultant at Remi I have been involved in designing, architecting and implementing a new serverless backend API from the ground up. I have consulted and mentored a remote distributed Scrumban team, led features development and maintenance, promoted good engineering practices and gained further experience with serverless architecture in AWS Lambda and Auth0 SSO.

TeachSurfing is a nonprofit social enterprise with a social mission to enable people to share their knowledge and culture with local communities. TS’s global platform is connecting individuals who would like to share their knowledge voluntarily with not-for-profit organizations, schools and communities with learning needs. The platform is serving over 2800 users and 240 host organizations from 131 countries.

As a consultant to the company I was primarily architecting and implementing further services of the platform as well as whitelabel migrations for 3rd party organizations and Single-Sign On solutions. While the work focused on the technical backend implementations, decisions scope was wide and included product and project levels as well as close work with frontend development, DevOp tools and various Java based frameworks. Another part of the work was to craft and maintain a roadmap to gradually shift to newer technologies and tools based on a microservice architecture, while maintaining legacy codebase and current functionality.
