Über mich

I started my career in IP networks in 2004 and still proceed to work and develop myself in that area. My experience continue in contribution with providing service excellence working as third level network support engineer in data center, customer LAN support and Internet services delivery at HP. One of my roles is as high level point of escalation of incidents which need special deep technical knowledge attention and problem resolutions which helps me to perfect my troubleshooting skills and dealing with very complicated cases. Changing of the configurations within customer infrastructure are part of my duties as change supervising, preparation and implementation which includes as well risk assessment. I am also a single point of contact for customer network infrastructures which I am in charge of. This role includes monitoring of the infrastructure, reporting of the capacity utilization and proactive observation of any possible point of failure which has to be taken into account and improved. Problem management is also subject of my duties where reasonable solutions should be purposed as a result of performed root cause analysis.
My experience in enterprise services started at Interoute Bulgaria as IP design and provisioning engineer and one year later I had a chance to be nominated as Principal engineer at the same department. As principal engineer I had a difficult but very interesting task to be team lead dealing with prioritizing of the work load and technical supervisor within the team, central point of contact and escalations regarding trouble tickets and customer change requests. In the part of provisioning engineer I had a chance to participate in three projects which include WAN connectivity of customers’ sites spread around the world. For one of the projects I was lead and for others was backup engineer. These projects included provisioning and supporting during implementation phase of MPLS VPN, Internet and Multicast services.
All of the above mentioned requires continuously increase my qualification and experience and gradually contributes for improving of my professional, organizational and communicative skills. As for my interests I keep pace with Cisco and Juniper products and solutions. I’m following their certification program. I am also prepared with knowledge at cisco CCIP-CCNP service provider level.
I am enthusiastic to develop myself and to deal with work related to my qualification, professional purpose and interests. I would like to participate within teams, where with my contribution will extend my knowledge and skills.
About my English I would notice that type of my work insists to use it every day. My interests at the same time is to learn German and I already started to expand my knowledge.
About myself I would say that I prefer project organized work. I sympathize to the so called “Open enterprise” environment in which every employee should be aware of company needs and takes his own responsibility in teamwork. I am highly motivated for hard working and focusing at the same time into achieving best results in each case - which means striving for more satisfied customers, sustaining teamwork and good working environment as well as contribution for improving working process.
Along with abovementioned I believe that I will be able to contribute and helping within achieving of set targets.

I will be glad to have a chance to speak with you in more detailed manner and discuss the ways for successful collaboration.

Looking forward to hearing from you.
