Database: MySQL Others: TCP/IP, Ethereal/Wireshark ## Work Experience ### Staff Software Engineer @ Spirent Communications Jan 2015 – Present | San Francisco Bay Area Currently I am working as a software engineer for the Spirent Landslide IMS product. Landslide is a test tool used to validate the performance, scale, call quality, authentication and charging functions of the IMS network with real-world device emulation at the scale of millions of voice & video calls and IP messages. Worked on Gm, ISC, Mw, Mx, Ml interfaces Environment: C++ on LINUX Protocols: SIP, Diameter, TCP Tools: Jira, Perforce ### Software Engineer @ Cisco Jan 2014 – Jan 2015 | San Francisco Bay Area I worked in the Small Cell Solutions team as a software engineer. Our team created end to end small cell solutions; this involves integrating the access points, security gateway, femtocell gateway and the core network and then testing the overall solution. Recently we have been moving towards virtualization and automation of the virtualized solution deployment. Working on development of Click to deploy tool, which installs various 3G & 4G components on a UCS B & C series server. This is a GUI based application that enables all of the virtual machines, applications, and configurations to be set up and validated across the entire infrastructure on standard computing hardware. This reduces the deployment time from months to minutes. Worked on the virtualization of the CISCO Small Cell solution. Small Cell HetNet Virtualization involves putting the Small Cell HetNet Gateway and OAMP components into UCS hardware. Load testing for virtualized and conventional HNB-GW and Security Gateway using CISCO tools such as Syfer and fern. Involved in the deployment and testing of an alpha network (enterprise network) inside SJC16 Cisco building, where we test the handover of 3G calls between the various access points inside the Enterprise Grid. The output of the test was provided to the access point development team to improve the handover code to achieve less than 1% call failures during handover. Worked on deployment and testing of an in-house Android App called “Cisco SWAT”, this App can be downloaded from Google Play and can be installed on any Android phone. This App does CS (circuit switched) and PS (packet switched) calls at regular intervals based on a predefined configuration These phones can then be placed at stationary locations to run load/soak test or can be moved around in a cart to test handovers inside Enterprise Grid. ### Senior Software Engineer @ BTI Wireless Jan 2012 – Jan 2014 | Cypress CA I was handling Customer support for the HNB Gateway product. The product was deployed in various Chinese cities. Design BTI HeNB Gateway for the 4G network. • Develop S1AP Encoder/Decoder for HeNB Gateway per TS 36.413 • Extending the existing 3G Gateway design to suit the 4G gateway ### Senior Software Engineer @ Kineto Wireless Jan 2008 – Jan 2012 | Milpitas CA Design, develop and test modules and software stacks in Kineto’s INC product. Worked on various product lines at Kineto i.e. Iuh, IuGAN and Femto pre-standard version and the specialization area has been the Core Network interface (RANAP-SCCP-M3UA-SCTP) towards the MSC/SGSN, the Access Network interfaces(RANAP/RUA, HNBAP and UPP) towards the FAP/HNB, the RADIUS interface to the AAA server and the H.248 Interface to Media Gateway. ### Systems Engineer @ Veraz Networks Jan 2006 – Jan 2008 | San Jose, CA Worked on the testing of the Interconnect Border Connect Function (IBCF) in Veraz Softswitch. IBCF protects the carrier network against malicious attacks, and provides key security features including topology hiding, access control lists for “denial of service” attack prevention and Network Address Translation (NAT) - Performed Sanity testing of ISUP, SIP, H.323 calls for daily nightly builds - Wrote SI test plan and Perform SI Testing for the IBCF feature - Performed Load testing of the IBCF and the SIP Interface using third party tool called Mu dynamics - Wrote bugs and followed up with developers for their resolution ### Technical Leader @ Aricent Jan 2004 – Jan 2006 Worked on enhancement of the SIP interface (ICE) of Veraz Control Switch. SIP Interface acts as a Gateway and terminates incoming SIP calls. My work involves enhancement of existing state machines, call control and implementing new RFC such as Diversion Header, Reason Header, and OPTIONS etc. ### Senior Software Engineer @ Hughes Software Systems Jan 2002 – Jan 2004 SIGTRAN protocol suite has 5 Signaling Protocols (SUA, M3UA, M2UA, M2PA, and IUA) and a transport layer protocol (SCTP) and I was part of the support team handling about 10 active customers. ### Software Engineer @ Hughes Software Systems Jan 2000 – Jan 2002 Development if M3UA and SUA stack . M3UA is a protocol for supporting the transport of any SS7 MTP3-User signaling (e.g., ISUP and SCCP messages) over IP using the services of the Stream Control Transmission Protocol. SUA is a protocol for the transport of any Signaling Connection Control Part-User signaling (e.g., Transaction Capabilities Protocol (TCAP), Radio Access Network Application Protocol (RANAP), etc.) over IP using the Stream Control Transport Protocol. ## Education ### B.S. in Computers Aligarh Muslim University ## Contact & Social - LinkedIn: https://linkedin.com/in/akhtar-iqbal-2259867 --- Source: https://flows.cv/akhtar JSON Resume: https://flows.cv/akhtar/resume.json Last updated: 2026-04-12
