• Built the product solo end to end: architecture, dashboard, API, infrastructure, billing, docs, pricing, and the customer conversations. Empty repository to a live multi-tenant SaaS with organizations, paid plans, a public API, and a GitHub Action other people install.
• Architected the runtime as isolated parallel workers behind a Fastify orchestrator, with per-agent timeouts, shared Zod contracts across every service boundary, and a retry policy that retries only infrastructure faults, so one agent failing never fails a run.
• Built the billing and entitlements stack behind a provider-agnostic payment seam: signature-verified webhooks deduped by event id and applied idempotently, multi-currency plans, and usage meters computed from the source of truth so they cannot drift.
• Designed a 23-component shared UI package consumed by every surface in the monorepo, so a verdict, a status, or a metric renders identically in the dashboard, the pull-request comment, and the public report.
• Built a precision/recall/F1 evaluation harness over fixture cases that regression-guards agent quality as models and prompts change.

React, Angular, TypeScript, Node.js, Python, REST/GraphQL, PostgreSQL, Redis, NX, Jest, Cypress, Playwright, Docker, AWS, CI/CD

• Own developer-facing analytics and AI features end to end for a multi-tenant platform serving thousands of embedded-analytics requests daily: React and Angular interfaces, typed REST and GraphQL contracts that customers build against, Node.js and Python services, and the tenant-isolated data layer beneath them.
• Shipped a production GPT-4 assistant that turns natural-language questions into interactive charts, then cut latency 40% by reading production traces and fixing what they pointed at: tokenization, Redis caching, and query optimization.
• Led the system design for an NX micro-frontend migration that cut build time 60% and made a large codebase safely divisible across teams.
• Raised automated coverage from 65% to 92% with layered Jest, Cypress, and Playwright suites in CI/CD. Partner with Product and Design on scope and API shape, and mentor 5+ engineers.

Node.js, Express, TypeScript, REST APIs, Microservices, MongoDB, PostgreSQL, Docker, GitHub Actions, AWS Lambda

• Built the REST APIs and Node.js microservices behind the platform, handling thousands of requests daily at 99.9% uptime across MongoDB, PostgreSQL, Docker, and AWS.
• Engineered ingestion pipelines and connectors for 5+ external data platforms including BigQuery, Snowflake, and PostgreSQL, each with its own auth model, rate limits, and failure modes.

Python, Django, OCR/Tesseract, Java, Windows/.NET

• Delivered security-reviewed applications for government clients and designed an OCR translation pipeline on Tesseract that eliminated manual data errors across thousands of documents monthly.
• Built a cross-platform deployment tool that took enterprise installation from days to minutes, saving 120+ IT staff hours per deployment cycle.
