Backend developer at AppsGem building AI-assisted property scraping workflows on AWS serverless architecture.

Cuba
Message

At AppsGem, I implemented web scraping across multiple sites in an event-driven serverless architecture, routing each property address to a county-specific Step Function. This reduced manual processes from hours to minutes.

I also developed components of a visual, low-code scraping engine and integrated AI-assisted flow generation from natural language, helping nontechnical users create extractions without HTML or programming knowledge. I built a Claude diagnostic skill to identify failed order actions.

At Datamart, I implemented services for a card-issuance lendbot that collects applicant data, evaluates business rules, and notifies the bank, automating approvals that previously required manual review. Earlier, I adapted a data-mining algorithm using Apache Spark and MapReduce and configured a distributed processing cluster.
