Work History
MID DATA ENGINEER
Bogart Associates
01.2025 - Current
- Collaborated daily with database administrators to understand legacy data structures and map out how that information would transition into a modernized system.
- Led working sessions to plan how data should be normalized, standardized, or aggregated so developers could reliably access it through new APIs.
- Used Databricks and PySpark to parse, clean, and integrate large datasets into AWS, ensuring data quality and consistency throughout the migration.
- Stored and indexed integrated data in OpenSearch (OSS), tuning structures so the development team could query it efficiently.
- Worked closely with application developers to reconstruct JSON schemas that matched their needs, iterating with them to design objects that were intuitive to consume and easy to render on the web.
- Documented data flows, transformation logic, and integration decisions so future teams could understand how and why the new system was built.
- Designed and refactored poorly performing legacy code resulting in 82% cost reduction on processing and storage.
FULL STACK DEVELOPER
Novetta/Accenture
04.2021 - 08.2024
- Maintained and extended a Go‑based API while building new React interfaces for a military application, translating complex requirements into reliable, production‑ready features.
- Partnered with UI/UX designers to evaluate design feasibility, shape technical constraints, and plan component architecture before development began.
- Analyzed designs to identify reusable components, define custom UI needs, and sequence work for efficient delivery.
- Collaborated with database administrators and used Swagger to map backend data structures, understand API contracts, and plan how frontend components would consume and transform JSON responses.
- Utilizing AWS S3 SDK I was able to develop APIs (in Go) to List, Copy, and Move object data within our S3 bucket namespace. Maintained clear documentation of testing workflows, and coding standards for reference by other team members.
- Led backend architecture for a C# application, designing data models, service layers, and APIs that cleanly parsed incoming data, queried the database, and returned structured JSON to the frontend.
- Implemented backend logic for data retrieval, transformation, and persistence, ensuring accuracy, performance, and maintainability.
- Worked closely with UI/UX teams to align design ambitions with technical realities and guide decisions based on system constraints and timelines.
- Supported frontend development by writing C# client‑side code to consume the APIs I built and integrate data into the application’s UI.
- Acted as a technical point of contact across teams, ensuring backend, frontend, and design efforts stayed aligned and delivered cohesive functionality.
SOFTWARE ENGINEER
IBM
01.2019 - 03.2021
- Researched, designed and implemented scalable applications for data extraction, analysis, retrieval and indexing.
- Collaborated with senior software staff to produce new cloud capacity storage software solutions.
- Performed software testing to uncover bugs and troubleshoot issues prior to application launch.
- Developed Middleware applications by applying experience in Python, Go and Java programming languages.
- Analyzed code defects and failures and presented code refactors and design fixes.
- Worked with front end developers to write Go APIs to send and receive data for the application.
SOFTWARE ENGINEER
NantHealth
08.2016 - 01.2019
- My primary role as a software engineer, is to maintain Java based Device Driver SDK, and implement automation processes for verification and validation.
