Application Security Engineer - Contract
Strike 7
Overview
As an Application Security Engineer at Strike 7, I collaborated with a cross-functional development team to build a full-stack SaaS platform powering an AI-driven hacking engine. The platform enables Managed Service Providers (MSPs) to assign security testing packages to clients, while also allowing clients to directly purchase packages and execute automated penetration tests. I contributed to both frontend and backend development using Nest.js and TypeScript, designing scalable RESTful APIs, implementing business logic, and building responsive user interfaces. PostgreSQL was used for structured data management with optimized schemas and query performance considerations. Cloud infrastructure such as AWS and DigitalOcean supported deployment and hosting. Secure coding practices, input validation, authentication and authorization controls, and application security testing were integrated throughout the development lifecycle. The platform also integrates AI-related services including mem0, Browserbase, and Langfuse to support intelligent automation and observability, all developed using AI-assisted workflows to accelerate delivery while maintaining code quality.
