I am a seasoned Healthcare IT Implementer (HL7 and IHE implementer) working knowledge and experience with Mirth Connect, Qvera, Infor Cloverleaf, InterSystems Ensemble integration engines and HealthShare HIE platform in developing and providing healthcare IT interoperability solutions. In the last 10+yrs I have implemented over 200+ HL7 v2-v3 /IHE interfaces (from ADT, ITI-8, ITI-22, ITI-18, ITI-41, CCD/CCDA, ORM, ORU, MDM, etc.) across various integration engines.
In the recent past I worked part-time on an integration project for a healthcare organization to gather content from various sources of clinical content (i.e. MS SQL Server, flat files and HL7 msgs) to drive creation of HAI reports published to the CDC NHSN following Clinical Document Architecture (CDA) standard.
For my projects I commit to providing a functional design and maintenance documents as deliverable's for my design and implementation efforts. The design document would detail the functional specifications of the design & architecture and the maintenance document would detail how to continue to support the solution. In addition, I would be willing to mentor or assist in transitioning materials and knowledge for the solution. Thank you for your time for considering me for your project opportunity.
I am responsible, available and punctual to project deadlines. My goal is to satisfy every client on every project I am involved in. Thank you!

I build HIPAA-compliant healthcare software: telehealth, RPM, and EHR/FHIR integration that passes audits and holds up under real clinical load. I also bring hard fintech compliance depth (ACH, payments, audit logging) for products where correctness isn't optional. Most engagements start with a fixed-price design phase that defines architecture, scope, and roadmap, then convert into fixed milestones, so delivery stays structured and budget predictable.
🏗️ THE PROBLEM I SOLVE
Most healthcare and fintech software fails because compliance, security, and messy real-world data are treated as afterthoughts. A failed EHR integration stalls a launch. A data breach costs millions. A system that buckles under load costs you users.
I design systems that survive the real world. With 8+ years across telehealth, RPM, EHR integration, and regulated fintech, I turn complex ideas into secure, high-performance products that pass HIPAA, SOC 2, and GDPR audits.
📊 PROVEN TRACK RECORD
✅ SUNNY TELEHEALTH: HIPAA-COMPLIANT RPM PLATFORM
Remote patient monitoring with automated device sync (wearables, Apple Health, Garmin), compliance dashboards with risk stratification, and EHR integration over HL7/FHIR. Built an AI early-warning model (0.96 AUC) that flags adherence failure weeks ahead, plus automated billing under CMS codes.
✅ DAMEN CAPITAL: HIGH-ASSURANCE FINTECH PORTAL
Loan-servicing and payments portal with full ACH lifecycle, tokenization, idempotent payment webhooks (HMAC-verified), and an immutable audit log. Passed financial compliance audits and supported the client's multi-million-dollar raise. Node.js, Fastify, Supabase.
(More work, including an AI multi-tenant assistant and a document-automation engine, in my portfolio below.)
🧠 CORE TECHNICAL EXPERTISE
⚕️ HEALTHCARE
HIPAA/PIPEDA/GDPR • HL7, FHIR, CCDA, X12 EDI (270/271/835/837) • EHR/EMR (Epic, Cerner, Athenahealth, eClinicalWorks, NextGen) • Telehealth, RPM, ePrescribing, RCM, patient portals
💳 FINTECH
ACH (NACHA), Stripe Connect, tokenization, idempotent payments, immutable audit logging, fraud detection, multi-currency ledgers
⚙️ ENGINEERING
Node.js, NestJS, Python (FastAPI/Django), PostgreSQL, React/Next.js, TypeScript, AWS/Azure, Docker/Kubernetes • Clean Architecture, DDD, RBAC, multi-tenancy (RLS), idempotent webhooks, CI/CD
🤖 AI WHERE IT HELPS
RAG pipelines, LLM integration (OpenAI, Claude, Gemini), vector search (Pinecone, pgvector), eval harnesses in CI, applied to real clinical and financial workflows, not bolted on
🤝 HOW I WORK
✓ Architecture-first: Fixed-price discovery (1-2 weeks) → clear milestones
✓ Transparent: Regular updates and Loom walkthroughs, no silence
✓ Available: 30-50 hrs/week, on-time delivery
✓ Quality: Clean, documented, tested code. No corners cut.
📩 LET'S BUILD SOMETHING THAT SCALES
If you're building in healthcare or fintech where compliance and reliability actually matter, I take full ownership, bridging business needs and technical execution, from architecture to live deployment.
Send me a message or invite me to your job. I typically respond within an hour, and I'm happy to hop on a quick 15-minute scoping call to see if we're a fit.

I build AI systems that reason, not just match vectors, From RAG-based chatbots to AI agents powered by Neo4j and OWL-based ontologies. Worked with Mercedes Benz, Philips and QpiAI before to make smart RAG and semantic knowledge systems.
Hi, I'm a Ontologist + Graph Engineer with 2+ years of production experience helping startups and enterprises turn complex knowledge into smart, conversational systems
Here are some of the things I know how to do:
⦁ LLMs & NLP: Raptor, GraphRAG, prompt engineering, semantic search, vector databases.
⦁ MLOps & Deployment: MLflow, DVC, CI/CD (Jenkins, CircleCI), model ensembling.
⦁ Ontology Engineering (OWL, SWRL, SKOS, Turtle): Crafting rich knowledge graphs with logical reasoning in Protégé.
⦁ RDF & Data Transformation: Structuring raw data into interconnected RDF triples. (JSON-LD, XML)
⦁ Semantic-AI Fusion: Blending symbolic reasoning with neural retrieval strategies like Raptor, Fusion, Query Expansion, Contextual Retrieval, and Re-ranking
⦁ Structured LLM Responses: Ensuring reliable, schema-aligned outputs using Pydantic for validation and API interaction
⦁ Model Integration: Leveraging OpenAI, open Source Models -LLaMA, Gemini and vector databases for efficient hybrid search.
If you're building AI that needs to truly understand — not just retrieve — I’d be excited to collaborate.
