CURRICULUM VITAE (CV)

TECHNICAL COMPETENCE

My experience in technology ranges the depths of low level programming to system administration in servers and architectural design for service delivery.

With a background deriving from Turbo Pascal as a first experience to the ISO of C and progressively moving forward to the JIT / AOT compiled high end languages following the ECMAScript specification.

—

There is a very obvious pattern shown over the years of adventures as an engineer in the UNIX and Linux particular namespace, carrying a genuine interest and love for the principles behind the Operating Systems and their relevant ecosystems. Alongside the interest of these UNIX particular ecosystems, the security fundamentals and stability guidelines act a building block in the knowledge I’ve gathered throughout the years.

This has lead to extensive assertions and optimizations implemented in large scale projects. As a first hand choice in the personal workspace I dedicate my time inside the Debian GNU Linux environment, tiling windows and constantly progressing my routines in an effort to improve my development workflow. Over recent years I’ve spent my time exploring the dynamics of ECMAScript and the Node.js universe, being an early adopter of the ideology of asynchronous IO and event driven programming paradigms. I’ve always paid a special attention and interested payed to scaling dynamics, data normalization and performance of services, I approach software development and architectures with an experience coming from conventional patterns, ranging from climates of enterprise to startups.

Challenges are something I strive to participate, and I enjoy the nature of cutting edge technology in an effort to learn and discover better ways of achieving the goals I need to.

—

In my role as a Technology Officer, my work has consisted of a diverse field of areas, listed below


TECHNOLOGY

  1. Bridge business product and delivery model to infrastructural engagement and technological solutions that needs to meet high demand in growth, acceleration and market acquisition targets with geographically distributed deployments. Implementing service accessibility using virtualization technology, from bare-metal data center and continental peer point provider in network backbone.

—

  1. Design and implement a hybrid service oriented architecture (SOA) in a private cloud, compliant of SLA quality service composition following the industry standards of 6-dimension scaling axis with linear and horizontal growth of services on software and hardware layers.

—

  1. Implement capacity for replicated environments to meet High Availability SLA (Service Level Agreement)-levels in fault tolerance on hardware and service levels to meet service delivery requirements from customers.

—

  1. Plan and route capacity exercises in data center to acquire optimal data transfer rates in isolated environments using hardened security protocols on secure private networks bonded to utilize private corporate cloud technology.

—

  1. Utilize isolated execution of services, kernel specific optimizations for performance and load aggregation with LXC technology on virtualization layers of Proxmox PVE utilizing dedicated bonded networks to reduce surface exposure from public and private facing services.

—

  1. (High Availability) implementation of GlusterFS as a distributed file system between LXC services to increase performance between LXC to hypervisor I/O exchange, highly optimized on a multi cast network layer. Providing snapshot backup and recovery capacity to hypervisor nodes with automated channels to external storage and improved performance on replication between services.

—

  1. (High Availability) implementation of BIND9 DNS - domain management using custom security hardening configurations and added query caching for acceleration of DNS resolution internally and externally of the service platform using master - slave syndicates.
