Increased the visibility of over 80% of data by creating a dashboard service deployed in AWS, aggregating data from multiple sources and exposing statistics and reports. Reduced the lag of report building by 90% by designing a series of granular events for each change in the source systems, handling them asynchronously for real-time report refreshing.

Increased the number of users by 50% by developing an AWS cloud-based dropzone solution, ingesting files through an S3 bucket and processing S3 events via an SQS messaging queue. This addressed the client's inability to offer AWS-based file ingestion services.

Eliminated over 100k duplicate products globally by creating an event-based asynchronous deduplication service. This service cleaned redundant barcodes, reassigned scattered vendor products, and archived duplicates, addressing low user satisfaction and high data maintenance costs.

Eliminated the risk of outdated SKU statuses by 100% by creating a Kubernetes cronjob. This cronjob utilized an SKU updating runner to set statuses according to stock events and activation dates, resolving issues with product status updates.

Saved 50% of the time spent on storing data changes by creating an SDK to incorporate an auditing framework into applications, automatically saving every change into new designated tables. Considerably decreased by 90% the time spent on extracting reports on audited fields by storing data in a distributed in-memory caching database.

Eliminated the risk of debts not being collected by 100% by architecting a collecting mechanism that paid debts and triggered upon new funds. Drastically increased sales reps' productivity, selling over 10x more loan products by designing a stable and scalable disbursement service within a new microservice.

Increased the number of transactions by over 20% and users by 250k by designing an installment plan REST API. This API validated eligibility status for each transaction and generated plans based on account offers retrieved from the database.

Increased the client's portfolio of trades by 30% and generated over $300k extra a month by creating an integration application using Apache Camel routes. Drastically reduced the time to close a deal by up to 50% by designing a highly accurate matching service.

Ensured 100% clarity into the client's products by building a PoC application from the ground up, providing a 360-degree perspective of key tools. This showcased fault-tolerant databases and easy-to-use enterprise development frameworks, building REST APIs and integrating with cloud solutions.

Greatly improved underwriters' productivity by more than 6x and generated over 10k insurance policies by developing and integrating over 10 new products. This involved configuring entities and the application server, maintaining consistency with atomic transactions.

Decreased the time spent on managing devices by more than 10x by developing a digital solution containing a REST API with CRUD operations on established entities. This allowed devices to be looked up and assigned in seconds.

Eliminated booking conflicts by 100% by streamlining the reservation process and creating an Android application for classroom booking using Google Sign-in. Reduced time gaps, saving over 30 hours a week, by creating a quick booking feature scanning QR codes.
