What shipped
- Led a latency optimization initiative that reduced end-to-end response time from roughly 900ms to roughly 320ms through pipeline and infrastructure tuning.
- That's the difference between a call that feels robotic and one that feels human, and it's the same discipline applied to every client build.

These pages describe systems KeenCraft has actually built or is still building. They do not borrow metrics from other products. Where a number is named, such as a latency change or a milestone count, it is from that engagement. Where a number is not named, it is because it was not measured for publication. Use the bullets as the scope that shipped. If you want something in this shape, the comparison that matters is the role, the industry, and whether the system is live, still in a milestone plan, or already delivered.
Rawk.ai is listed because the work is real and the role is specific: Lead Developer, live, Voice AI Infrastructure.
KeenCraft prices this work as a fixed Statement of Work. The scope, the milestones, and the total are written down before build starts. A stage is tested before that milestone is treated as done. Work that shows up later is scoped and priced on its own, not folded into the original invoice. A written proposal usually lands in 2 to 5 business days after a strategy call, and the timeline is agreed before any code is written.
Questions about this work
What is Rawk.ai?+
A live platform for creating and deploying custom conversational voice agents. KeenCraft was lead developer.
What was the latency result?+
End-to-end response time dropped from about 900ms to about 320ms through pipeline and infrastructure tuning.
Why does that latency number matter?+
Sub-400ms responses are what make a voice agent feel like a conversation instead of a delay. The same discipline is applied to client voice builds. How that latency sits in the build fee is in what an AI voice agent actually costs in 2026.
