I'm a software engineer in Toronto. I lead teams at startups, mostly building secure distributed systems and infrastructure for user-owned data. I run a small studio on the side for ideas I can't let go of.
Hey, I'm Kahtaf
Some things I've shipped
-
Built an Android dashboard app that hit 1M+ downloads. Lifehacker picked it up
-
Led the design and implementation of the Vana Data Portability Protocol , a decentralized architecture for user-owned AI data
-
Led the team that built r/datadao , the first Data DAO. TechCrunch wrote about it
-
Hold a couple of patents on non-custodial data encryption
-
Run BitSpice , a small software studio where I build things I want to exist
Here's a bit more about me.

Work Experience
See all work- Head of Applications → Technical LeadSep 2024 - Current
Led a full-stack team shipping consumer apps on top of Vana’s protocol. I focused on translating Web3 primitives into UX that felt normal to Web2 users, without compromising on privacy or permissions. Owned the Vana App and staking products, scaled the applications layer to 100k+ users, and set up PostHog and Sentry so we caught issues before users did.
Later took over as technical lead and ran the overhaul of Vana’s Data Portability protocol: wrote the spec, got the team on the same page, and shipped the implementation. Owned delivery across TypeScript and Python services, Postgres, and the infra surface (GCP + Cloudflare). Sped up PR throughput and time-to-prototype by pushing clearer specs and tighter review loops. Wrote the kind of end-to-end tests and docs that engineers actually use.
- Senior Software Engineer → Technical Lead → Engineering ManagerMar 2022 - Sep 2024
Joined as an early engineering hire. Designed a patented method for encrypting large datasets using a Web3 wallet (non-custodial encryption and decryption), then built the data wallet and secure APIs around it. Also built a framework for offline, in-browser data processing so we didn’t have to route everything through centralized services. Audited cloud spend and cut the AWS bill by roughly 90%.
As technical lead, took an AI image generation app from idea to launch in two weeks, then kept it running as usage grew past 1M users. Rebuilt model-wrapping APIs as models improved, cutting waste in storage and compute. Wrote design docs that let frontend and backend work in parallel instead of handing off sequentially. Ran technical interviews and helped grow the engineering team.
Moved into engineering management, leading a team across backend, frontend, data, and ML. We built an API for third-party developers to deliver personalized AI experiences, with privacy and security as hard requirements. That included an OAuth-based permissioning system for sensitive user data. Wrote and maintained API docs so integration didn’t require tribal knowledge. Worked with leadership to keep platform work pointed at actual user problems.
