Profile
I work where application code meets production reality.
I’m a software engineer focused on backend systems, distributed architectures, and AI-powered applications. At Alphatec Spine, I design and operate production microservices and APIs for a HIPAA-compliant medical cloud platform.
My day-to-day work includes eliminating race conditions, designing idempotent workflows, investigating failures across service boundaries, and improving API and database performance.
Outside of work, I ship SaaS products and real-time applications to explore agent workflows, RAG, MCP, computer vision, WebSockets, and systems programming.
Technical capabilities
Tools organized by the problems they solve.
Production experience across the application lifecycle, from API contracts and data models to deployment, observability, and incident response.
Cloud & Distributed Systems
Reliable asynchronous workflows that tolerate retries, partial failures, and concurrency.
AI & Machine Learning
Source-aware agents, tool-calling systems, and applied computer vision pipelines.
Data, Quality & Observability
Measurable software with fast feedback loops in development and production.
Selected work
Systems I’ve designed and shipped.
Each project explores a different systems problem: grounding AI in context, turning conversations into structured data, and synchronizing real-time state.
01
Live product
AI-assisted SaaS · Three-service architecture
Backlogr
Helps developers, QA engineers, and product owners refine software tickets before implementation by analyzing issues, comments, screenshots, and indexed source code.
- Challenge
- Surface missing requirements, ambiguous behavior, edge cases, and relevant implementation files before work begins.
- Architecture
- LLM agent workflows grounded by RAG across a Quarkus API, FastAPI AI service, Angular client, and Redis-backed coordination.
- My role
- Product design, distributed architecture, agent behavior, retrieval pipeline, full-stack implementation, and deployment.
02
Customer-facing SaaS
AI agent · Tool calling · MCP
NexMenus
Turns conversational business input into structured menu and storefront data, giving food businesses a faster path from an idea to a customer-ready digital presence.
- Challenge
- Convert incomplete, conversational input into a dependable structured menu without hiding important decisions from the user.
- Architecture
- A Java 21/Quarkus agent orchestrates menu-creation tools, exposes them through MCP, and powers an Angular and TypeScript experience.
- My role
- Designed and built the product end to end, then worked directly with users to troubleshoot issues and refine the workflows.
03
Live multiplayer game
Real-time systems · 3D physics
Sumo Car
A multiplayer 3D driving game with physical steering, collisions, and a shared world synchronized in real time through a Rust backend.
- Challenge
- Keep independent browser clients synchronized while preserving responsive physics-based vehicle control.
- Architecture
- Three.js and Rapier run the 3D simulation while a Tokio-based Rust service manages sessions and broadcasts player state over WebSockets.
- My role
- Built the physics model, multiplayer protocol, concurrent server, shared-world state, and browser experience.
Additional work
Applied machine learning
Computer vision · Quality inspection
Surgical Screw Detection
Production object-detection pipeline using YOLOv8, PyTorch, Python, and OpenCV, with targeted retraining workflows for new failure cases.
Computer vision · Subject selection
FoodPhotoEnhancer
AI pipeline combining Grounding DINO and SAM to identify a dish, build a detailed mask, and select the most likely main subject for enhancement.
Experience
Building reliability into every layer.
Alphatec Spine
