Full Stack & DevOps Engineer | Expert in React, Node.js, Spring Boot, AWS, Docker, Kubernetes | Scalable Solutions for Web & Cloud

Hi there! I’m Jefferson Clinton Youashi, a passionate and results-driven Full Stack Developer and DevOps Engineer with over 4 years of professional experience architecting, building, and scaling software applications.

With a strong academic foundation in Software Engineering and industry exposure through remote and on-site roles, I bring the best of both worlds: hands-on coding skills and systems-level thinking. I’ve had the opportunity to work on high-impact projects across diverse environments—from startups to open-source communities—delivering robust solutions that serve real-world needs.

What I Bring to the Table:

Backend Development: Mastery of Node.js, Express.js, Java (Spring Boot), NestJS, and PHP. Designed and maintained RESTful APIs, microservices, and high-performance backend systems.

Frontend Development: Expert with React.js, Next.js, Tailwind CSS, TypeScript, and SASS to deliver stunning and responsive UIs with a strong focus on usability.

DevOps & Cloud Engineering: Proficient in setting up CI/CD pipelines (Jenkins, GitHub Actions), containerizing apps with Docker, and orchestrating them via Kubernetes. I also manage infrastructure with Terraform, Ansible, and AWS (EC2, S3, VPC, IAM, ELB).

Database Mastery: Comfortable working with both SQL (MySQL, PostgreSQL) and NoSQL (MongoDB, Redis) technologies, with deep attention to optimization and scalability.

Monitoring & Performance: Experienced with Prometheus, Grafana, and ELK Stack to monitor systems, log data effectively, and ensure uptime.

Soft Skills & Team Collaboration: Adept at mentoring interns, collaborating with cross-functional teams, and communicating technical ideas to non-technical stakeholders.

I’m also multilingual (fluent in English and French) and have worked on global open-source projects through platforms like OnlyDust, where I contributed to both frontend and backend layers for better user experience and scalability.

🏆 Awards and Recognition:

Work Terms

Availability: I am available for both short-term contracts and long-term engagements. My time zone is GMT+1 (Cameroon), but I’m flexible and have worked with clients across multiple time zones.

Communication: I maintain active communication and prefer to stay transparent throughout the development cycle. I’m available via Guru messages, email, and video conferencing tools like Zoom or Google Meet.

Project Management & Tools: I am comfortable using Agile methodologies and tools like Jira, Trello, GitHub Projects, and GitLab. I prioritize regular updates, version-controlled code, and milestone tracking to ensure progress and quality.

Deliverables & Quality: I ensure that all deliverables are:

Fully tested

Well documented

Secure and scalable

Aligned with client requirements

Payment Terms: I typically work on a per-project or hourly basis, with milestones for larger contracts. I prefer payments through the SafePay system to ensure security and satisfaction for both parties.
