SoftServe (outsourcing company) / Lviv, Ukraine / May 2020 – July 2020

Client: FORTUNE 100 US COMPANY
Project description: Intelligent Proxy is an inline system that inspects web and DNS traffic to support
its acceptable use and threat mitigation use cases. The system identifies the web applications and
content to classify the traffic to determine if the transactions should be allowed or blocked based on
the policy configurations.

Responsibilities/contributions:

• Enhanced deployment pipelines to production/stage/dogfood/early in various locations (15
datacenters worldwide)
• Improvement of existing monitoring and creation of the new ones
• Developed the rollback system with the support of canary deployment (based on the internal
containers orchestration tool).
• Developed the reference framework for microservices smoke tests (initialization, readiness, liveness
checks) for easier troubleshooting and on which stage service failed.
• Client incidents resolution

Tools & Technologies: Python 3, Bash, Grafana, Graphite, Prometheus, DataDog, Terraform, Debian,
AWS, Docker, Jenkins, Quadra (internal containers orchestration tool), nginx, Computer networks,

PYTHON/GO ENGINEER
SoftServe (outsourcing company) / Lviv, Ukraine / December 2019 – May 2020

Client: FORTUNE 100 US COMPANY
Project description: Intelligent Proxy is an inline system that inspects web traffic to support its
acceptable use and threat mitigation use cases. The system identifies the web applications and content
to classify the traffic to determine if the transactions should be allowed or blocked based on the policy
configurations. The first tool (debug-check) is used by the customers and support team that they can
use this tool as the first step in troubleshooting to verify whether the traffic is protected by Intelligent
Proxy and to collect debug info at the browser level. The main purpose of the second one (policy
simulator) is the simulation of the request from a customer (using his real IP, policies, organization ID,
etc.) to a specific domain/URL and receive a detailed response from all services with various
information.

Responsibilities/contributions:

• Implemented all major features of both tools in Golang without prior experience in this language
• Transformed the PoC into a ready-to-use tool
• Created integrations with a dozen of other Intelligent Proxy services that are written in multiple
languages (Python, Golang, C++, Node.js).
