• Frontend Technologies: Experience with modern JavaScript frameworks (e.g., React, Angular, or Vue.js) and standard HTML/CSS.
• SMPP Libraries: Familiarity with SMPP libraries such as Cloudhopper (Java), jSMPP, node-smpp, or Python's smpplib is highly advantageous.
• Databases: Solid understanding of relational (MySQL, PostgreSQL) and/or NoSQL (MongoDB, Redis) databases.
