Founder-led SaaS delivery
Short, bounded engagements where UX, implementation, and product judgment all need to happen at once.
Matthew Hendricks · Westmark.dev · @watthem
Clear product thinking. Calm technical delivery.
I help small teams turn messy software work into clear systems, working MVPs, and documentation people can actually use.
Westmark is the client-facing consulting shop. Support handles one-off jobs. @watthem is where I publish tools, docs, and experiments.

Product and delivery work across trading infrastructure, developer documentation, internal tools, and founder-led software bets.
Where I’m focused right now
Replay and queue systems
I am consolidating internal tooling around IQue: a queue-first runtime for agent-assisted delivery, replay, and time-travel debugging.
Documentation as proof
Live docs, architecture notes, and working software are part of the portfolio, not an afterthought.
