What I'm looking for

I’m looking to build secure, telecom-grade web platforms—integrating RADIUS/AAA and network gateways—while owning APIs, RBAC, and subscriber lifecycle logic. I want an Agile team that values QA discipline, performance, and maintainable architecture.

I’m a Full Stack Web Developer with 3+ years of experience specializing in ISP backend systems and web application development. I build telecom portals that connect smoothly with Free RADIUS AAA and deliver reliable subscriber experiences end to end.

In telecom-focused work, I integrated 2G/3G packet core components into centralized Free RADIUS for unified subscriber tracking, and built backend middleware to sync user profiles and quotas between billing portals and legacy HLR/HSS systems. I also developed and deployed ISP BNG management portals to manage the full subscriber lifecycle from activation through expiry.

I bring practical expertise in PPPoE/DHCP provisioning, RADIUS attribute configuration (including VSAs), session accounting, and NAS-level policy enforcement. I’ve also implemented RBAC across admin dashboards and reporting modules for NOC teams, enforcing OWASP security practices like parameterized queries, CSRF protection, and role-gated access control.

Beyond development, I have SQA experience—designing test cases and regression suites, logging and tracking defects, and supporting root-cause analysis with clear QA documentation. My goal is to keep building secure, scalable systems that telecom teams can operate confidently, using Agile delivery and clean API-driven architecture.
