I'm not really interested in talking to people about sports, politics or anything. When I talk to people I just ask them about their personal life. Most people are happy to discuss it. They don't get asked that question much. I just keep asking questions. and then the conversation ends and I leave
Ken Griffin on how markets have evolved and become more efficient over his career
Back in the day, you could just pick up the phone and call up executives at companies to discuss their stock. No longer exists today
Worth a listen
These 4 moves solved 95% of my lower back problems.
1) Bird dogs teach your spine to stay stable as your limbs move.
2) McGill crunches teach your abs to brace without spinal flexion.
3) Side planks strengthen the obliques needed for lateral stress.
4) Hip thrusts wake up and strengthen the glutes.
Do 10-15 reps every day for 21 days and thank me later.
Senior Backend Engineer (AI + Payments)
We’re building a global, API-first payments platform. The core is already live — payments API, ledger, commerce, checkout, dashboards, infrastructure. Much of the codebase has been generated by AI.
💰 $30k–$40k/month · Remote · Contractor
We need someone who can look at all of this and say: “this will break in production” — before it actually does.
What already exists
- Full payments API (PaymentIntents, Refunds, Customers, Charges)
- Double-entry ledger with atomic entries
- Native commerce engine (Products, Orders, Fulfillment, Inventory)
- Hosted checkout, Merchant Dashboard, Admin Portal — all deployed
- API Gateway in Go (auth, rate limiting, circuit breaking)
- 60+ PostgreSQL tables, strict TypeScript, versioned migrations
- Async workflows for webhook delivery and settlement
- Terraform managing 183+ AWS resources
- CI/CD with smoke tests and automated deploys
Your mission
Be the last line of defense between code and real money. Concretely:
1. “This will break in production”
Identify failure points before they cause downtime — silent crashes, missing restart policies, monitoring gaps, non-recovering processes
2. “This code will cost us money”
Double charges, race conditions in the ledger, lack of idempotency, unsafe refund/dispute flows, incomplete reconciliation
3. “This is a security risk”
Exposed secrets, missing encryption at rest, misconfigured VPCs, unauthenticated endpoints, injection vectors in AI-generated code
4. “This database will fail”
Unsafe migrations, lack of backup/disaster recovery, unindexed queries, broken transactions, schema changes causing downtime
Day-to-day
- Deep audit of AI-generated backend code (TypeScript + Go)
- Review financial flows to identify edge cases that could cause losses
- Validate infrastructure decisions and highlight reliability risks
- Build integration tests proving critical flows work end-to-end
- Ensure observability is strong enough to detect issues in minutes, not hours
Stack
TypeScript · Hono.js · Drizzle ORM · Go · PostgreSQL (Aurora Serverless) · Redis · Temporal · Docker · AWS ECS Fargate · Terraform · Cloudflare
We’re looking for someone who
- Has 5+ years in backend engineering, preferably in fintech/payments
- Has operated production systems handling real money — incidents, postmortems, on-call
- Can audit AI-generated code and spot what AI misses
- Has strong intuition for “this will break” before it does
- Knows PostgreSQL deeply (transactions, locking, migration safety, disaster recovery)
- Has experience with observability (tracing, alerting, runbooks)
- Values accuracy over speed — a ledger bug in production is worse than a week of delay
Nice to have
- Experience with PCI DSS compliance
- Familiarity with double-entry ledger systems
- Experience with Temporal or distributed workflows
- Go for high-performance services
- Experience finding (and fixing) financial bugs in production

This is one reason why it's easy for Americans to move around to different areas in the country. And why they are ideal expats. They keep to themselves.
Other foreigners have a hard time dealing with new places because they aren't used to atomism
Operating in stealth mode is almost always a mistake.
Talk publicly about what you're building. You’ll build momentum, get real feedback, and someone will reach out with the other half of your idea you didn’t realize you were missing.
6 billion people around the world would trade places with you for an American corporate job. That is the golden ticket for many foreigners.
It lets you leave at 5pm, makes you a millionaire at the end of your life with your 401k, you sit in an office all day
There are stuff in real life that cannot be transmitted in books and stuff in books you can never pick up in real life.
The disease is the inclination to learn from books what you must learn in real life and attempts to reinvent from experience what can only be found in books.
