Yassir O. T.
Full Stack Dev | Cybersecurity SaaS & AWS Infrastructure
I build and maintain complex SaaS platforms for the cybersecurity industry — from API architecture and backend systems to frontend interfaces, containerized infrastructure, and cloud deployments on AWS. For the past 6 years, I have been the lead developer of a security awareness training platform used by organizations across multiple industries to defend against phishing, social engineering, and AI-generated threats. My core responsibilities include: • Designing and building RESTful API using PHP and the Laminas framework • Developing Vue.js 3 frontend integrated with PHP legacy systems • Managing asynchronous workloads through RabbitMQ message queues • Operating dual database architecture: MySQL for transactional data, DuckDB for analytical reporting • Deploying and maintaining all services in Docker containers across a shared network • Managing cloud infrastructure on AWS: EC2, S3, and Route 53 I also work with SciRev, an academic platform for the scientific community, expanding my experience beyond security into data-driven web applications. I work best on long-term engagements where I can develop a deep understanding of the product and contribute beyond just writing code — helping shape technical decisions, architecture, and roadmap priorities. If you are building or scaling a SaaS platform in cybersecurity, compliance, or enterprise software, I'd like to understand your project.
