As a software developer at America's #1 Telehealth Company, as ranked in 2022, I had the chance to be involved in a variety of projects.

In this role, my security background led me to lead our in-house security guild for three months, focusing on fortifying the web app's defenses and best security practices.

Effective communication with senior engineers and stakeholders fostered a collaborative environment where seamless feature development occurred with security as a priority. Colleagues commended this skill.

Working closely with junior engineers was rewarding. I provided guidance, helping them navigate technical challenges and understand ticket requirements.

As a team, we prioritized optimizing user experiences, introducing compelling features, and conducting meticulous A/B testing. This focus resulted in heightened engagement and positive feedback from users.

Noteworthy projects included:
• improving overall SEO ranking of the website.
• enabling data-driven decisions through tools like Grafana and Prometheus.
• obtaining valuable KPIs for evaluating team performance.
• streamlining CI/CD pipelines, reducing deployment time.
• incorporating new infrastructure with Terraform and GCP, bolstering performance and scalability.

As a software engineer at Germany's #1 E2E encrypted Health Information, we delivered a secure and usable digital health platform with user security in mind.

I have been a front-end developer since the product's early days, which led me to hire and mentor new members. I was also an active contributor to the internal security team and assisted with implementing multiple features on the platform.

As a senior software developer at DHIS2, I have diligently crafted specifications for new projects in close collaboration with product designers and managers. Effective communication has been first in my mind, successfully communicating timelines and addressing issues with peers and stakeholders.

I take pride in guiding and supporting junior engineers, assisting in feature delivery, and offering valuable training on daily processes and systems. In this regard, a few of my contributions extend to pair programming with other engineers, engaging in detailed code reviews, and helping them navigate their role requirements.

I introduced E2E testing using Cypress, and we covered over 35% of the already introduced features. This has left developers and stakeholders with a more peaceful night's sleep.

Moreover, I have been instrumental in enhancing our CI/CD infrastructure and reducing Docker image sizes, leading to faster and more reliable deployment times. This optimization has resulted in a more efficient and robust development environment.

As a DevOps engineer at ReDi School, a nonprofit tech school, I took charge of vital infrastructure projects which impacted the platform's performance and scalability.

Noteworthy projects included migrating all existing infrastructure from AWS to Azure and improving performance.

I had the opportunity to lead the implementation of CI/CD pipelines for existing and greenfield projects, harnessing the power of GitHub Actions and Azure.

Lastly, we leveraged Terraform, which helped us manage the infrastructure of both back-end and front-end environments.

As part of my role at Vimcar, I had the chance to lead the implementation and relaunch of their new website branding.

I implemented a modern solution using Next.js and Contentful, which focused on the website's SEO ranking.

The Product Managers' Toolbox is a simple app where PMs can search for different techniques and methods they can use within their teams.

I developed this toolbox independently, implementing the web application and its continuous delivery.
