Who I Work With
Series A–C fintech founders, payment and lending platforms, and VC/PE investors who need executive-level technical judgment before the stakes get higher.
What I Offer
Downtime costs revenue, ledger integrity is non-negotiable, and legacy tech debt slows every release. GrassSeed brings pragmatic, executive-level architecture to solve exactly these problems.
Platform Resilience
Eliminate single points of failure across payment engines, ledgers, and servicing workflows before they become outages.
Scalable Architecture
Cloud-native system design that sustains transaction throughput as volume grows and avoids costly rewrites.
Legacy Modernization
Incremental migration paths off aging servicing stacks that protect uptime, data integrity, and compliance.
Executive Technical Leadership
Board-ready guidance on roadmaps, hiring, and vendor decisions, with senior CTO judgment at a fraction of the full-time cost.

No pitch decks, no boilerplate proposals. Every engagement starts with a diagnostic session to surface risk, quantify technical debt, and clarify what’s actually blocking scale. From there:
We align on a context brief covering platform constraints, compliance obligations, and success metrics.
You receive a scoped proposal with tiered pricing that reflects the level of risk and urgency.
A short questionnaire is built into the booking flow, so the first session goes straight to substance.
Let’s Talk
Book a 45-minute strategy session. We’ll map your platform risks, scaling constraints, and what technical success looks like.
A few targeted questions are built into the booking flow so we can skip the introductions.
If we work together, the session fee is credited to your engagement.
