About

Matthew Pazaryna

Principal software engineer and hands-on technical leader with 40 years of experience delivering products from enterprise platforms to modern AI applications. I design agentic-first engineering systems that apply specialized AI agents across the classical software development lifecycle, from discovery and requirements through architecture, implementation, review, UAT, release, and operations. People remain accountable for business meaning, technical synthesis, security decisions, acceptance, and production. Agents expand execution capacity and preserve traceable evidence. My background spans full-stack product development, healthcare data integration, platform modernization, and privacy-first AI.

Experience

Principal Software Engineer & Consultant

Jul 2023 — Present

Independent · Remote

Designing and leading agentic-first software delivery: a practical implementation of specialized AI agents across the complete SDLC, proven through production healthcare platforms and AI-enabled products.

  • Designed and implemented an Agentic SDLC that coordinates specialized agents from discovery and requirements through architecture, implementation, independent review, testing, UAT, release work, and operational evidence.
  • Defined durable contracts between stages: source-backed requirements, PRDs, execution specifications, acceptance scenarios, bounded agent assignments, test evidence, UAT findings, and exact-release records.
  • Kept authority explicit throughout the system. Domain experts decide business meaning; the principal engineer owns architecture and synthesis; accountable people retain security and acceptance authority plus production control.
  • Proved the model as the senior builder for Proactive Logic's Agave platform, owning architecture, technical planning, implementation, verification, plus release preparation. The production pharmacy benefit management enrollment system transforms incoming correctional enrollment feeds into EDI 834 documents.
  • Built the modular .NET 10 and SQL Server pipeline for parsing, canonical persistence, day-over-day delta detection, exception controls, EDI generation, telemetry, plus operator-facing evidence, with React and TypeScript interfaces.
  • Delivered v2.7.1 with a release-era verification record of 2,611 passing .NET tests, 328 web unit tests, and 63 Playwright end-to-end checks.
  • Architected Chiro, a privacy-first clinical documentation application using SwiftUI and on-device Apple MLX inference so sensitive patient data remains on the device.
  • Led full-stack delivery of Resin, a nonprofit fundraising analytics platform, from data pipelines and agentic workflows through production deployment on Vercel.
  • Created Kairos, an open-source AI-augmented productivity system that combines agentic workflows with load-based self-regulation.
  • Established reusable engineering practices for AI-assisted teams, including specification-driven development, documentation hierarchies, and staged delivery workflows.
