• Designed and built an internal AI sales assistant using a FastAPI (Python) backend and provider-agnostic LLM orchestration, enabling sales teams to match products with potential clients and query customer data, credit limits, and purchase history in natural language with real-time SSE streaming. Currently in production and under active monitoring ahead of a formal impact review.
• Built bank file-based integrations for electronic payments, eliminating duplicate data entry in the banking portal and manual status updates, significantly reducing operational errors.
• Architected and shipped a full-stack field operations platform with .NET Web API, Flutter Web, and an offline-capable Flutter mobile app, replacing manual paper-form registration. Scaled the system from a pilot project to manage 74% of total operations (processing over 900 livestock cataloging sessions, 3,000 lots, and 191,000 animals year-to-date in 2026). Achieved 79% team adoption, drastically reducing manual form transcription and unlocking geographic tracking and operational data analytics.
• Delivered an integration layer around the core business system using .NET Web API, creating a stable boundary for external consumers and enabling integration across multiple internal and third-party applications while isolating them from the underlying legacy platform.

• Developed a .NET automation tool for mass video overlay generation, reducing production processing time by 87.5% during peak digital catalog periods.
• Built secure data-extraction integrations between the auction management system and downstream production systems, eliminating manual data entry.

A database-free system that composites custom image overlays onto videos using FFmpeg, with direct S3 uploads and fully asynchronous processing.

• Architecture: Event-driven pipeline using S3 → SQS → AWS Fargate, with job state inferred from object storage. The .NET 10 Minimal API runs on AWS Lambda for upload/status operations, while a containerized worker handles rendering.
• Frontend & Infrastructure: Astro + React frontend with an interactive canvas designer; Pulumi IaC with isolated development and production stacks.
• Engineering: Implemented idempotency, distributed locking, and failure handling using S3/SQS, with Outside-in TDD using WebApplicationFactory and LocalStack. Documented key architectural decisions with ADRs.
