Work Experience

Technical Lead, Cloud Engineer

Scopic Software

August 2021 - August 2022

I was a Technical Lead and an architect in two projects, overseeing two teams of approximately five developers each, along with a project manager and a QA. My responsibilities include communicating with the client, making technical decisions, and adapting the development process to meet business requirements. My key contributions were: Designed an environment for the devs and QA, which would facilitate a Kanban style of development, where a certain feature can be implemented and then tested in isolation, and then deployed to production when ready. The team moved to daily deployments with smaller incremental changes, which were easier to rollback in case of issues. And the client could see and validate his ideas in production with minimum delay.

Security auditor

AWS DevOps

July 2020 - August 2021

I served as an AWS DevOps engineer and security specialist, assisting a team of developers in building a Big Data project in healthcare. My responsibilities included maintaining approximately 25 different AWS services using CloudFormation templates, contributing to a custom-made framework for deploying CloudFormation templates, and creating infrastructure in line with best security practices. My key contributions were: Auditing the infrastructure for HIPAA and GDPR compliance and creating remedial tasks for developers.; The infrastructure successfully passed security audits and penetration testing conducted by a third-party company.

Senior Software Engineer, Lead Cloud Engineer

TripShock

June 2018 - July 2020

I held the roles of tecnical lead and DevOps engineer at an American online travel agency. I managed a team of developers responsible for the serverless architecture in AWS, extensively utilizing Node.js and other cutting-edge technologies. My key contributions were: Implemented CI/CD pipelines with automatic unit and functional testing for Lambda functions and Docker containers in AWS; Managed the integration project with the Reserve with Google service, which, upon launch, resulted in a significant increase in new trip bookings; Managed other integrations with online travel agencies; For integrations, designed a microservice system built on AWS Lambda and DynamoDB, which, leveraging the free tier, incurred minimal costs for the business.

Senior Backend Developer

StartSightings.com

June 2012 - July 2018

I served as the lead PHP developer at an American startup, where I held responsibility for all key decisions related to project architecture, implementation of new features, refactoring of legacy code, database schemas, and distributed computations. My key contributions: Led the rewriting of legacy code to the Symfony framework, implementing the transition incrementally without disrupting existing functionality. This resulted in a shorter development cycle, enhancing overall code quality and reducing the barrier to entry for new team members; Reduced the number of queries to the database by an order of magnitude through the incorporation of an ORM; Optimized a range of complex SQL queries, with a specific focus on enhancing the efficiency of geospatial queries among other intricacies; Implemented integration of a NoSQL database to optimize user notification processes, reducing latency and enhancing the suppression mechanism for similar notifications; Implemented a distributed notification system using the Pub-Sub model and message queues. I played a pivotal role in the project's growth, contributing to a 4x increase in page views and a 6x expansion in the user base. At its peak, the project achieved 1 million page views and attracted 150,000 unique users.
