I am an experienced Software Engineer and Infrastructure Manager with technical expertise in building and supporting complex and legacy software systems using a mix of technologies such as JavaScript, Java, Python, and Linux for diverse clients. I have extensive team lead and independent work experience in the delivery of innovative solutions for clients.
Creating and developing innovative software solutions for clients across a broad range of industries.
Participate in scrums consisting of cross-functional teams, both software and hardware.
Ensure that features are being delivered efficiently and on-time.
Built and deployed a new ETL framework for data lakes with a volume of 10+PB.
Refactored and migrated the platform to a microservices-based architecture.
Established dev standards and best practices in transitioning several Python legacy systems to Golang.
Deployed and executed processes and standards to support in-house enterprise app instances on AWS.
Implemented new automation and optimization solutions to reduce costs and simplify deployment processes for Juul Labs.
Handled infrastructure verification tasks and provided provisioning tooling support for solutions on the project.
Designed, implemented and maintained a real-time traffic visualization solution for the client.
Reduced map-reduction costs by half using optimized algorithms and a changed storage scheme for the client.
Rewrote the C++ logging pipeline solutions on GoLang which also eliminated data losses on the platform for the client.
Architected, designed and worked efficiently on scheduling data processing for the client's systems.
Implemented an accurate real-time train positional algorithm based on several data feeds in the UK for the client.
Introduce an authentication proxy to reduce the visible failure rate of the third-party authentication providers.
Built and deployed a token-based authentication solution for video streaming on the project.
Worked on a new failover solution for video streaming over the HTTP protocols for the Swift Serve.
Developed and implemented a DNS load balancing solution for the client.
Designed and implemented new features and architecture working on projects for CNN, Nokia and Thomson Reuters.
Implemented new solutions for the client's product prototype - winning an award for EPAM.
Played a key role in the design and deployment of a new advertising solution for OviStore.
Wrote 3/4 of the new codes that served the internal EDI service for the client.
Implemented new solutions to decrease the time for resolving common technical issues to 1 hour.
Rewrote and refactored a legacy codebase with 1 million lines of code for the client.
Developed a billing and logging solution for distributed data analysis.
Replaces Hadoop-based systems with a real-time data calculation model.
Backend processing is executed on 6 CPU units serving hundreds of nodes.
Successfully migrated the analytics system to AWS.
A live-migration of an existing internal Hadoop cluster into AWS resulted in increased costs.
The move to AWS was achieved through a double drop in map-reduce costs.
Implemented a public train positioning algorithm.
Utilizes data feeds from UK transportation companies for precise train location.
Reduced API response times through significant database optimizations.
