The written story behind each project: the problem, the approach, the stack and the measured results. Project pictures stay on the home portfolio.

Enterprise Cloud & HealthTech

Health Management System

Healthcare admin platform where each role sees only what it should, and records open in under 85ms.

Healthcare organizations handled patient appointments, medical records, and billing with fragmented databases, leading to query lag over 900ms and compliance risks.

  • Query Latency: <85ms
  • Uptime Reliability: 99.95%
  • Compliance Grade: HIPAAverified

Client Hiring Portal

This site: a portfolio where a company can read the work, pick how to engage, and send a brief.

Hiring managers were reading a flat résumé and still could not tell which systems were production, which stack sat behind them, or how to start a conversation.

Health AI

Clinical Notes AI API

AI that turns a doctor’s free-text note into structured problems, medications and follow-ups.

Clinicians typed the same history twice: once in the note, again into discrete fields the billing and follow-up screens required.

  • Schema reject: closedkeys
  • Invented dose: 0stored
  • Extract path: 1API

Health APIs

Lab Orders & Results API

A secure connection between clinics and the lab: orders go in, results come back fast, and each clinic sees only its own.

Orders lived in email and shared spreadsheets. Results arrived late, and one clinic could see another clinic’s panel if the query was loose.

  • Result read: <90ms
  • Duplicate posts: 0applied
  • Tenant leak: 0in review

Health AI

Patient Message Triage API

AI that reads patient messages and sends each request to the right team, in under 2 seconds.

One message often held a refill and a new symptom. A single label sent the whole thread to the wrong desk, and urgent swelling waited behind billing.

  • Route time: <2sec
  • Label set: closedenum
  • Inbox sort: autofirst pass

Health Data & Cloud

Vitals Ingestion Pipeline

Device readings like heart rate and blood pressure, cleaned up and shown live in under 100ms.

Device vendors posted bursts of vitals. Bad samples (a heart rate of 0, a duplicated timestamp) landed in the chart next to real ones.

  • Latest read: <100ms
  • Rejected samples: rulespython
  • Ingest: Kinesisburst

API Platform

Clinic Partner API

One documented, secure API so outside systems can book appointments and get updates without custom builds.

Each new clinic integration was a private endpoint and a Slack thread. Partners could not book or read a schedule without a custom build.

  • Contract: v2stable
  • Booking replay: 1appointment
  • Partner docs: Postmancollection

Applied Machine Learning

Appointment No-Show Risk Model

Machine learning that predicts which appointments are likely to be missed, so staff confirm those first.

Reminder calls went out in schedule order. Staff spent the morning on patients who always attend, and the slots that went empty were the ones nobody had time to confirm.

  • Model: Logisticregression
  • Evaluation: Held-outtime split
  • Output: 3risk bands

Recommender Systems

Rental Recommendation Engine

Personal suggestions for the next vehicle or property a renter is likely to book, including brand-new listings.

The listing page showed the same popular assets to everyone. New listings never surfaced, and repeat renters had to search from scratch each time.

  • Models: 2blended
  • Cold start: contentfallback

Billing Anomaly Detection

Machine learning that spots unusual invoices for review before they go out, without needing past examples of errors.

There were no labeled examples of bad invoices. Reviewers either checked everything by hand or relied on fixed rules that missed new kinds of mistakes.

  • Labels needed: Noneto train
  • Method: k-means+ Gaussian
  • Review: Humanin the loop

Support Ticket Routing Classifier

Machine learning that sends each support ticket to the right team, and leaves unsure ones for a person.

Tickets landed in one shared inbox and were sorted by whoever picked them up. Misrouted tickets bounced between teams before anyone started on them.

  • Models compared: 2NN vs trees
  • Low confidence: Abstainto shared queue
  • Output: Softmaxmulticlass

Engagement

Choose how we work together

01

Join your team

A senior engineer inside your team. I work in your codebase, standups and code reviews, and stay long enough to own a real part of the product. Under the hood: Laravel, Node.js, Python or AWS.

Full-time or long contract
02

Work solely for your company

A dedicated engineer for one company. I take the product from planning to the live version: backend, data, hosting and screens, with your product as my focus.

Dedicated contract
03

One project

A clearly defined build, then a clean handover: an MVP, taking an AI-built prototype (Lovable, Bolt, Cursor) to production, a migration, or an AI feature. Get in touch to discuss scope and pricing.
