CASE STUDY 02 / ORBITAX
Engineering for complexity.
Reliable distributed workflows, faster data access, and enterprise tax tools built across six years of engineering contributions.
01 / CONTEXT
The challenge
Enterprise tax software combines complex calculations, data-heavy workflows, and distributed operations. My work at Orbitax addressed these challenges across multiple products and roles.
02 / OWNERSHIP
My responsibility
I progressed from Associate Software Engineer to Senior Software Engineer, contributing to backend and frontend development, workflow architecture, and mentoring.
03 / THE WORK
Engineering contributions
Remove a legacy data dependency
Migrated Forms Data from Microsoft SQL Server to MongoDB, eliminating calls to the legacy platform and improving API speed by 50%.
Coordinate distributed workflows
Implemented the SAGA pattern to improve distributed workflow reliability and reduce scenario duplication processing time by 20%.
Build enterprise product capabilities
Designed and developed Audit Tracker 2 with ASP.NET Core Web API and Angular. Delivered a SpreadsheetGear-based spreadsheet solution using Event Sourcing and contributed to tax-calculator scenario and document workflows.
04 / THE BIGGER PICTURE
Architecture perspective
Distributed workflows need explicit coordination and recovery behavior. The diagram shows that general concern; these results came from separate Orbitax contributions, not one unified project.
05 / IMPACT
What changed
- Improved Forms Data API speed by 50%.
- Reduced scenario duplication processing time by 20%.
- Improved entity import/export workflows by 20% through in-memory caching.
- Mentored junior engineers and interns, led technical sessions, and participated in code reviews.
Based on my professional experience as summarized in my resume. Figures are specific to the contributions described; underlying benchmarks and proprietary implementation details are not published here.
