Full-Stack Developer at Sure Response Technologies securing a healthcare location system and building an internal sales calling platform.

United States

Message

At Sure Response Technologies, I develop Swift plugins for a Flutter-based healthcare location system, integrating BLE beacon scanning, MQTT messaging, and iOS background processing. I also hardened the system against SQL injection and implemented row-level security for sensitive customer data.

I designed, built, and deployed an internal sales calling platform on a self-managed Linux VPS, integrating Zoho CRM and Dialpad REST APIs. I secure and administer the production Linux servers, audit application code, and build endpoint monitoring.

At Washington University, I automated FASTQ file organization with Bash and Python and analyzed AI-generated output. I also built CipherLab, a browser-based tool that detects and decrypts 44 cipher types, and developed PhishGuard, a platform for authorized internal phishing simulations.
