What I do
Design and build full product flows from interface to backend and deployment-ready structure.
About Me
Software engineer building and operating multi-tenant SaaS platforms for healthcare and logistics — schema design, async backends, mobile, security, and deployment, with a focus on compliance-aware architecture and correctness under concurrency. Built a HIPAA-aligned medication platform integrated with Epic's FHIR sandbox; hardened three production sites to A+ on securityheaders.com.
What I optimize
Performance, maintainability, and user clarity so software remains dependable as it grows.
What I am targeting
Systems engineering, platform engineering, and software roles with strong ownership scope.

Technical Projects
Patient Triage API
Spring Boot REST API · Solo Project
A REST API for patient intake and urgency-based retrieval, built with Spring Boot 3 and Java 17. Includes Jakarta Validation, a priority queue for triage ordering, and a full JUnit 5 test suite.
- Java 17, Spring Boot 3, Spring Web, Jakarta Validation
- Maven, JUnit 5, multi-stage Dockerfile
- GitHub Actions CI passing on every push
Dispatch Assignment Patterns
Java 17 · SOLID & Concurrency Patterns
A small Java module demonstrating SOLID principles, pluggable selection strategies, tunable retry policy, and safe concurrency in a dispatch assignment service.
- Java 17, no external dependencies
- Strategy pattern with four interchangeable rider-selection strategies
- Idempotent job claiming via AtomicBoolean and Future timeouts
- Pluggable audit logs (in-memory or file-backed)
Load Balancer Patterns
Java 17 · Producer-Consumer & Concurrency
A worker-pool implementation with pluggable distribution strategies for routing incoming jobs across a fixed set of consumers.
- Java 17, no external dependencies
- Pluggable strategies: round-robin and least-loaded
- BlockingQueue per worker with poison-pill shutdown
- AtomicInteger pointer and LongAdder completion counts
Drone Telemetry Platform
Java 25 · Spring Boot 4 · PostGIS · Grafana · Leaflet
An end-to-end telemetry platform for drone flights. Ingests DJI flight CSVs into PostgreSQL/PostGIS with spatial indexes, auto-detects low battery, weak signal, and geofence breaches, serves the data as GeoJSON via REST, and visualizes it in Grafana and an interactive satellite map with flight replay.
- Java 25, Spring Boot 4.1, PostgreSQL 16 + PostGIS 3.4
- Flyway migrations, GIST spatial indexes, JdbcTemplate batch inserts
- GeoJSON API, Leaflet map with live HUD and playback controls
- Grafana dashboards provisioned as code, Docker Compose
- 8 tests — 4 unit, 4 Testcontainers integration with real PostGIS
Clinical RAG Platform
Java 25 · Spring Boot 4 · pgvector · HNSW · RAG
A retrieval-augmented generation platform for clinical documents. Ingests free-text notes, chunks them with overlap, embeds chunks into PostgreSQL with pgvector, retrieves the most relevant context for a query, and generates citation-grounded answers through a pluggable LLM provider.
- Java 25, Spring Boot 4.1, PostgreSQL 16 + pgvector 0.8
- HNSW cosine index, top-K retrieval, source metadata
- Pluggable embedding + LLM providers with deterministic mocks
- Citation-grounded prompt construction, per-query metrics
- 15 unit + 10 integration tests with Testcontainers
Clinical Triage + RAG Integration
Java · Spring Boot · Multi-service · RAG · OpenAI · PostgreSQL + pgvector
Two Spring Boot services talking over HTTP. The Triage API scores patients on eight clinical factors and ranks them by severity tier, then calls the RAG platform with the top-ranked patient's full clinical picture. The RAG platform embeds the question, retrieves the most relevant clinical note from pgvector (HNSW cosine index), builds a citation-grounded prompt, and returns a cited clinical recommendation. Combined response includes ranked patients plus an answer sourced from the trauma note.
- Triage API — rule-based multi-factor scoring, PriorityQueue, RestClient
- RAG platform — pgvector + HNSW, OpenAI embeddings, GPT-4o-mini
- End-to-end response: ranked patients + cited clinical guidance
- Retrieval distance 0.28 (trauma query) — tight semantic match
- 42 tests across both services — JUnit 5, Testcontainers
