Co-creator and Technical Director of a small Telecom Operator providing services in Europe and internationally, I actively participated in the development of a turnover of €37 million in 2015, a 400% increase since 2010 (Net profit multiplied by 13 in 5 years).

My recent missions can be summarized as follows:

o Design, configuration, installation, operation, security, maintenance, and optimization of the entire technical architecture and Voice network (VoIP & PSTN)

o Definition, configuration, operation, and improvements of management and supervision tools based on technical and commercial needs (OSS & BSS: QoS, pricing, billing, margins)

o Ensuring stable and continuous quality of service for all clients

o Implementation, coordination, and supervision of a support team (NOC) available 7 days a week

o Technical and pricing negotiations with more than ten technical partners: equipment manufacturers, datacenters, hosts, ISPs, software publishers and resellers, cable installers, brokers

My daily work environment is bilingual French/English

My expertise:

o VoIP: signaling protocols, media streams, codecs, and transcoding

o SBC and Media Gateways: IP architecture design, provisioning, trunk groups, IP peers, routing, numbering plan, access and traffic security, upgrades

o KPI Optimization: ASR, NER, ACD, PDD, MOS, latency, jitter, packet loss

o Troubleshooting: CDR & SIP trace analysis, audio problem resolution, fraud detection and blocking, billing discrepancy resolution

o Equipment installation and migration, cabling

o VoIP Codecs: g711, g729, g723, g722, g726, iLBC, amr…, topSkills=[], remainingSkills=[{"id": "Telecom", "type": "GLOBAL", "name": "Telecom"}, {"id": "Gestion de projet", "type": "GLOBAL", "name": "Project Management"}, {"id": "voip", "type": "GLOBAL", "name": "VoIP"}, {"id": "SIP", "type": "GLOBAL", "name": "SIP"}, {"id": "SBC", "type": "GLOBAL", "name": "SBC"}, {"id": "codec", "type": "GLOBAL", "name": "Codec"}, {"id": "QoS", "type": "GLOBAL", "name": "QoS"}, {"id": "Linux", "type": "GLOBAL", "name": "Linux"}, {"id": "troubleshooting", "type": "GLOBAL", "name": "Troubleshooting"}, {"id": "Documentation technique", "type": "GLOBAL", "name": "Technical Documentation"}, {"id": "Cahier des charges", "type": "GLOBAL", "name": "Specifications"}, {"id": "Gestion d'appel d'offres", "type": "GLOBAL", "name": "Tender Management"}, {"id": "Analyse fonctionnelle", "type": "GLOBAL", "name": "Functional Analysis"}, {"id": "Product Ownership", "type": "GLOBAL", "name": "Product Ownership"}, {"id": "Chef de projet informatique", "type": "GLOBAL", "name": "IT Project Manager"}, {"id": "ITSM", "type": "GLOBAL", "name": "ITSM"}, {"id": "Création d'entreprise", "type": "GLOBAL", "name": "Business Creation"}, {"id": "Conception rédaction", "type": "GLOBAL", "name": "Content Creation"}, {"id": "Gestion de projet technique", "type": "GLOBAL", "name": "Technical Project Management"}, {"id": "télécoms", "type": "GLOBAL", "name": "telecoms"}], experiences=[{"id": "59b5cf57db554c5e7af3bbce", "title": "Manager", "description": "+ Technical services in networks, telecoms & information systems for telecom players\n\n+ Design, implementation, and deployment of Voice services & architectures:\n o Telecom Expertise (VoIP & TDM): architecture design, installation, cabling, configuration, operation, maintenance, and migrations (router, VoIP gateway, and SBC)\n o Network Security: Network Access Control (firewall, Proxy, NAT, ACL) and Remote Access (IPsec, VPN, RDP) to ensure data/voice confidentiality, integrity, and availability\n o Information Systems: needs definition, solution design, and system configuration (OSS and BSS for telecom operators)\n o Independent Business Developer and trainer on Sonus Networks products (SBC5xxx and SWe)\n\n+ Creation and marketing of a consumer smartphone application:\n o Design, layout, and content creation (algorithms, data, graphic charter, visuals)\n o Management of development carried out by several service providers\n o Testing phase, bug reporting, and resolution in collaboration with developers\n o Market launch and sales management (eMarketing)\n o Available on iPhone, Android, Windows, and Mac OS\n\n+ Protection against electromagnetic waves and exposure reduction solutions:\n o High Frequencies: mobile telephony 2G/3G/4G, DECT, Wifi, Bluetooth, Microwaves\n o Low Frequencies: electrical equipment, radiators/convectors, cables/transformers\n\n+ Website design and development (flash, dreamweaver, photoshop, illustrator, wordpress)\n", "skills": [{"id": "Gestion de projet", "type": "GLOBAL", "name": "Project Management"}, {"id": "Création d'entreprise", "type": "GLOBAL", "name": "Business Creation"}, {"id": "Conception rédaction", "type": "GLOBAL", "name": "Content Creation"}, {"id": "Gestion de projet technique", "type": "GLOBAL", "name": "Technical Project Management"}, {"id": "télécoms", "type": "GLOBAL", "name": "telecoms"}]}, {"id": "59b5cef9db554c5e7af3a89d", "title": "Co-creator and Technical Director", "description": "+ Operation and Maintenance of the technical infrastructure and voice network:\n o Monitor the operation of information systems and equipment\n o Perform maintenance on information systems and equipment\n o Monitor and adjust the performance, capacity, and quality of routes\n o Monitor and analyze traffic to detect and limit fraud\n o Identify anomalies and apply corrective measures\n o Perform interconnection and quality tests for new routes\n\n+ Studies and Development:\n o Gather and define the needs of the company and clients, propose adapted solutions\n o Define, develop, and sustain the architecture of the network, tools, and information systems\n o Size and monitor the capacity of the network and its interconnections\n o Define and develop interconnections with new partners\n o Implement solutions for adjustment, evolution, and utilization of the network and tools\n o Conduct ongoing monitoring to improve company tools and architecture\n\n+ Engineering:\n o Increased automation of production, operation, and support\n o Concentration of operational actions for efficiency\n o Network migration and improvement, optimization and upgrade of equipment and tools\n o Ensure network reliability (hardware, electrical, and IP redundancy;
