Building production-grade systems for Healthcare, Legal Tech, and Video Streaming platforms — where correctness, compliance, and performance are non-negotiable.

I'm a senior full stack engineer with deep experience designing and shipping mission-critical software across regulated and high-throughput industries. I work across the stack — from low-level service design and database modeling to API contracts, frontend architecture, and cloud infrastructure — but my center of gravity is backend systems engineering: designing services that stay correct under load, integrate with messy real-world systems, and meet the compliance bar their industry demands.

I'm language-agnostic by design. I pick the right tool for the problem: Java/Spring for enterprise backbones, .NET for regulated enterprise platforms, Python/FastAPI for data-heavy and AI-integrated services, and Go for performance-critical concurrent workloads.

Working with PHI demands a different discipline. My healthcare work has covered:

• Standards & Interoperability — HL7 v2.x, FHIR R4 (resources, profiles, SMART-on-FHIR), DICOM, CDA, X12 (270/271/837/835)
• Compliance Engineering — HIPAA-aligned architectures, audit logging, field-level encryption, BAA-bound infrastructure, access control modeling, PHI de-identification pipelines
• Clinical Integrations — EHR integrations (Epic, Cerner/Oracle Health, Athenahealth), Mirth Connect / NextGen Connect interface engines, lab and pharmacy gateways
• Telehealth & RPM — Low-latency video consultation platforms, remote patient monitoring ingestion, device data normalization

Legal software lives or dies by document fidelity, citation accuracy, and matter-level security:

• Document Systems — Contract lifecycle management, clause libraries, redlining engines, OCR + structured extraction pipelines, e-signature workflows (DocuSign, Adobe Sign)
• eDiscovery & Review — Document review platforms, predictive coding, privilege detection, Bates numbering, production sets
• Case & Matter Management — Multi-tenant matter security models, conflict-of-interest checks, time tracking and billing, court e-filing integrations
• AI for Legal — RAG over case law and contracts, citation extraction (Bluebook-aware), clause classification, contract Q&A with provenance

Streaming is unforgiving — every millisecond and every megabit shows up in the user experience:

• Protocols — HLS, MPEG-DASH, WebRTC, RTMP, SRT, low-latency CMAF (LL-HLS / LL-DASH)
• Pipelines — FFmpeg-based transcoding farms, ABR ladder design, packaging (Shaka Packager, Bento4), DRM (Widevine, FairPlay, PlayReady)
• Real-Time Media — SFU architectures (Mediasoup, Janus, LiveKit), simulcast/SVC, signaling at scale
• Delivery & Observability — Multi-CDN strategies, origin shielding, edge caching, QoE telemetry, rebuffer/startup analytics

✓  Correctness before cleverness — especially in regulated domains
✓  Boring technology where it matters; novel technology where it earns its place
✓  Strong types, clear contracts, explicit boundaries
✓  Tests that describe behavior, not implementation
✓  Observability is a feature, not an afterthought
✓  Documentation is part of "done"
✓  Postmortems are blameless; processes are not

Specific clients are kept confidential. The shapes below describe representative work.

Architected a multi-tenant SMART-on-FHIR application bridging multiple EHRs (Epic, Cerner). Implemented field-level PHI encryption, HIPAA-compliant audit pipelines, and a HL7 v2 → FHIR translation layer processing millions of clinical messages weekly. Stack: Java / Spring Boot · PostgreSQL · Kafka · HAPI FHIR · AWS · Terraform

Built an AI-assisted contract review system with clause-level extraction, risk scoring, and provenance-backed Q&A. Designed the ingestion pipeline (OCR → segmentation → embeddings → vector search) and the matter-level security model with strict tenant isolation. Stack: Python / FastAPI · .NET (legacy integration) · PostgreSQL · OpenSearch · Kafka · React / TypeScript · Azure

Designed and shipped a hybrid live/VOD platform supporting LL-HLS playback under 3s glass-to-glass. Built the transcoding orchestrator, DRM packaging service, and a QoE telemetry pipeline driving adaptive CDN routing across providers. Stack: Go · Java · FFmpeg · Shaka Packager · Widevine / FairPlay · Kafka · ClickHouse · Kubernetes · Multi-CDN

A reusable ingestion + classification pipeline serving both legal eDiscovery and healthcare documentation workflows. Supports OCR, layout extraction, PII/PHI detection, redaction, and policy-driven routing — with full audit trails. Stack: Python · Go · .NET · Apache Tika · Tesseract · S3 · Kafka · Elasticsearch

• System design under real constraints — regulatory, latency, cost, team size — not just on a whiteboard
• Owning the full lifecycle — discovery → design → implementation → rollout → on-call → iteration
• Bridging domains and engineering — translating between clinicians, attorneys, broadcast ops, and engineers
• Stabilizing legacy systems — pulling distressed codebases back to production health without rewrites
• Mentoring — leveling up mid-level engineers and improving review culture, not just shipping code

• Senior / Staff / Principal full stack or backend roles
• Architecture consulting in healthcare, legal tech, or streaming media
• Long-term contracts where I can own a meaningful slice of the system
