Alexis's wealth of knowledge about computer infrastructure and systems architecture has allowed us to scale our business far past our competitors. Upon joining the team, we were all shocked by Alexis's work ethic and ability to plan and deliver on milestones well before the deadline. Not only does her work stand out on its own, the quality and efficiency by which she codes motivates the rest of the team to be better developers. Her team management and project management skills cannot be understated. Furthermore, she is a trustworthy and dependable manager of infrastructure, squashing issues before they surface and always quick to respond to messages. On this project, Alexis built out an entire data ingestion pipeline in Kotlin in just two weeks in order to address scaling issues. If you are looking for someone to transform your team and your product, I would full-heartedly recommend Alexis and I look forward to working more with her in the future.

Enterprise Systems Architect – API & Middleware Specification Blueprint
Extremely unprofessional experience. We had a structured, fixed-price contract, and all agreed-upon milestones were completed and fully paid. However, the freelancer chose to perform additional hours of unauthorized work completely outside of a funded milestone, and then demanded retroactive payment.
When I declined to pay for unauthorized hours—per standard Upwork protocol—the freelancer crossed a severe professional boundary. She bypassed me entirely and contacted my third-party corporate legal counsel directly in an attempt to disrupt my patent application filing and hold my company's intellectual property hostage.
This is a massive breach of contract protocols, client confidentiality, and basic business ethics. I highly caution any future clients against hiring this freelancer if your project involves sensitive data, intellectual property, or legal filings. She does not respect standard fixed-price boundaries or professional protocols.
