David L. Bowman
Hands-on engineering leader — Austin, TX.
Fifteen years of building production systems and the teams around them, from a single-engineer telehealth platform to a 55-person engineering organization. The work has been mostly TypeScript and functional architecture — schema-driven codebases with typed boundaries, Effect-TS at the core, and enough operational depth to carry a system from an empty repository through deploy, incident, and audit. Domains have run through telehealth, payments, e-commerce, real estate, and compliance-heavy platforms.
Where the work happened
OpenRouter
Software Engineer, Special Projects
- Building AI agent infrastructure on OpenRouter's Special Projects team. TypeScript, Effect, and a fair amount I can't talk about yet.
- Built and shipped the engineering behind Ori Eval. It scans a codebase for every model call site, generates evals against your own prompts, asserts on the tools the agent called and avoided, and ranks candidate models on cost, latency, and answer quality.
Oasys Therapeutics
Technical Advisor
- Set the technical direction for an early-stage therapeutics platform — Astro and React 19 on Cloudflare Workers, with the design system and component library established up front.
- Shaped the integration architecture: external provider network, pharmacy fulfillment, and Stripe payments.
Vitaal
Technical Advisor
- Set the technical direction for a telehealth prescription-fulfillment platform — Cloudflare Workers, D1, and Drizzle with an Effect-TS functional core.
- Shaped the patient-lifecycle orchestration across four Cloudflare Workflows.
- Guided the integration architecture across 8+ third-party systems: MDI clinical, Epiq pharmacy, NMI payments, Vouched identity, FedEx, Zoho CRM, Resend, and Better Auth.
The Innovation Lab (DLB Technologies, LLC)
Founder & Managing Partner — independent engineering practice
- Shipped 50+ startups end-to-end, architecture through deploy.
- Built schema-driven monorepos with end-to-end encode/decode boundaries.
- Remediated inherited production-database failures affecting tens of thousands of users without data loss.
- Closed data-leak vulnerabilities ahead of HIPAA-adjacent and LegitScript audits.
- Selected engagements: CarTalk, Ocean Block Capital, and a confidential healthcare platform.
Bright Development
Co-Founder & Managing Partner

Outside the codebase
Rabbinics and teaching
Ordained Orthodox rabbi (Machon Shlomo, Yeshiva University). Taught Jewish law and philosophy at universities, synagogues, and community programs, and published with Emory Law School on Jewish legal and ethical questions. This ran concurrent with the 2011–2018 consulting practice, which funded seven years of graduate study debt-free.
Education
- Rabbinical Ordination — Yeshiva University
- BBA — Kennesaw State University
