One of my key responsibilities is to deliver insightful leadership to a technical core team for steering overall IT projects from inception to completion. My priority is to improve the current test, upgrade, backup, restore, documentation, monitor, and data analysis solutions by developing and executing new methods and tools. In addition to this, I create strategic plans and guide the team in overseeing end-to-end delivery of IT projects by launching new network and system scenarios. Following are highlights of the key achievements that I attained:► Created thousands of lines of Python scripts that fully automated the monitoring, volume/cost/revenue/margin analysis reporting, and rate uploading processes. - Saved 10 hours a week of manual reporting; decreased incident detection time from 2 hours to 10 minutes; prevented $20K yearly negative margin of manual rate uploading; obviated the need of paying about $100K for third-party applications and licensing. ► Dropped 500K unsolicited SIP invites to save 20% of unnecessary storage usage by redesigning the network (to find all security leaks) and deploying new security filters, firewalls, and IP-Tables.► Conducted performance appraisals to identify, evaluate, and develop employees' work performance for achieving the organisation's goals and objectives.

As a Chief Technology Officer, I was at the helm of the affairs for directing a global team of 20+ IT experts to oversee end-to-end delivery of project MM$ large-scale projects, such as Bistalk international calls and Bisphone international messaging application. Moreover, I spearheaded the implementation of IT solutions from inception to launch, including VoIP-related servers, routers, firewalls, session border controllers (SBCs), media gateway controllers (MGCs), and soft switches. Selected accomplishments include:► Ensured the sale of external call service with monthly revenue of $75K+ by translating the dedicated protocol to standard authentication, authorisation, and accounting (AAA, RADIUS) for connecting to the third-party billing system. ► Enhanced professional competencies of the IT staff members by implementing more than 30 training programs and workshops.► Oversaw successful integration of the Bisphone (the mobile messaging application) with internal and external VoIP calls. Compiled dedicated own protocols (based on Jason Web Token) to the SIP RFC-defined protocol.

In this role, I am responsible for implementing and configuring the Cisco firewall ASA series, FortiGate, IP-Tables, and PF to strengthen information security for the internet, extranet business partners, and vendors. I have been instrumental in ensuring the proper maintenance of enterprise network and security systems by executing standard troubleshooting and automation practices. Also, I honed expertise in leading end-to-end deployment of servers with various operating systems, including Linux, UNIX, FreeBSD, and Windows. Key achievements for this role: ► Improved network performance with zero minutes of downtimes by implementing dynamic routing protocols (BGP, EIGRP, OSPF, VRF, IP SLA tracking) and physical redundancy.► Enhanced security of enterprise multi-location network with 100's of end-users and more than 1 gigabit/second of bandwidth usage.- Centralised and unified access-level management and ensured remote authentication by deploying and clustering Lightweight Directory Access Protocol (LDAP) and TACACS+.- Provided a complete picture of network traffic flow and volume by implementing and running NetFlow. Prevented thousands of daily cyber-threats at the network edge firewalls based on the recorded dropped cyber-attacks.

During this tenure, I led a team of 15+ NOC staff to manage ticketing systems and enhance troubleshooting processes to swiftly resolve partner's and management's issues.My key achievements for this role: ► Increased the partner's satisfactory from 50% to 95% based on the polling of the ticketing system at the time of ticket closure by developing the troubleshooting processes.
