Talks & content
Topics I carry.
I love speaking to tech folks — meetups, companies and events.
Careers without a map
Growing in tech when nobody hands you a plan — decisions, company changes, and what I'd do differently.
Engineering that becomes revenue
Lessons from e-commerce, fintech, logistics — and Singularity — on software that moves the top line, not just the backlog.
Mentorship at scale
What I learned mentoring developers — and how teams can build a mentorship culture without bureaucracy.
Real traceability: designing a hash that proves something
How to design a system that issues a unique, verifiable identifier for every event, and what changes when you have to prove later that the data was never altered.
Core ledger: the heart of anything that touches money
Double-entry, immutability and reconciliation explained for people who write code. Why a spreadsheet and a balance column always end badly.
Secure applications without a security team
The architecture decisions that prevent most incidents, for teams with no dedicated specialist. Threat modeling in an hour, with sticky notes.
Idempotency, retries and the art of not charging twice
The set of patterns that separates a system surviving partial failure from one that multiplies its own mistake. With cases from payments and logistics.
Architecture for a small team
Modular monolith, queues and observability at the right size. What's worth copying from big tech and what will only slow you down.
