Engineering Toolkit

Where every CryptoPrism backend runs. Zero ops, scales to zero, $0 when idle.

The Python web framework that doesn't get in your way. Pydantic types + async = joy.

Why I built a 72 PB pipeline instead of buying Glassnode — $36/mo after materialised views.

The default database. We run it on AWS RDS with 16 GB RAM and it's been boring for 2 years.

Cache layer for the pipeline. Memorystore $1,000 GCP credits carried us 18 months.

Every CI/CD pipeline. Watch out for the 60-day auto-disable — the keep-alive YAML is in the vault.

PDF generation for invoices. --no-sandbox + --disable-setuid-sandbox for Cloud Run.

Transactional + campaign email API. Webhook-based delivery tracking, 3K emails/mo free.

The default design tool. Auto-layout + variables changed the game for me in 2023.

For architecture diagrams that don't need to be perfect. Whiteboard feel, faster than Figma for thinking.

Photography when I need a hero image and can't justify a paid stock library.

Where the second-brain KB lives. Templates for SOPs, CRMs, project plans.

Personal knowledge base. Local Markdown files, Graph view, free forever. I sync via Git.

The only project management tool I don't resent. Fast, opinionated, keyboard-first.

Replaced Spotlight on macOS. Window management, snippets, scripts, AI — one launcher.

Invoicing + accounting for Indian SMEs. GST-ready, integrates with bank feeds, way better than Tally's UX.

Why we never use floats for money. One import line, zero 0.1+0.2 !== 0.3 bugs.

My primary dev tool. 80% of architecture decisions, 50% of code in any given week.

Local model runner for single-user dev workloads. vLLM when you need production multi-user.

Gateway proxy with fallback chain. Routes each request to the cheapest tier that can handle it.

Agent orchestration. Trinetry ERP uses 3 agents: invoice processing, smart reorder, client follow-up.
