I've been categorizing every transaction for over five years — from a 2 euro coffee to rent payments. At the end of each month I close the books and look at a 12-month forecast of where my money is going.

It started when I was 19 and ran my first company. I had no idea what I was doing with money, so I found an experienced financial advisor who sat me down and showed me how companies actually do budgeting. Where money goes, how much you're spending, what income to expect. Basic stuff, but nobody had explained it to me before. I just started applying the same approach to my personal finances and never stopped.

Once a week I sit down, drop my bank statements into an AI agent, and it parses everything — categorizes transactions, inserts them into the database, checks that balances match across accounts. If something doesn't add up, it asks me before fixing it.

I tried a bunch of apps over the years — CoinKeeper, ZenMoney, spreadsheets. They all worked to some degree. But the one thing I couldn't find anywhere was the ability to just hand an API key to an AI agent and let it read, write, and modify my financial data however it wants. Every app wants you to click through its UI and use its import flow. I wanted SELECT, INSERT, UPDATE, DELETE through a simple HTTP API that any LLM can call.

So I built it. During a vacation. Was supposed to rest, but I couldn't stop once I started. Migrated all my data from ZenMoney and never looked back.

The main view is a budget table. Past months show actual numbers — what I really spent and earned. The current month has both actuals and the plan side by side, so I can see how I'm tracking. Future months are pure plan — expected income, expected expenses, projected balances. Everything sums up across categories and months, so I can see at a glance whether I can afford a big purchase three months from now or if I need to cut something. It's basically how companies do financial planning, but for one person.

Under the hood it's Next.js 16 with TypeScript on top of Postgres 18. Row Level Security enforced at the database layer — not in the app code. API keys are SHA-256 hashed, plaintext is never stored. Exchange rates fetched daily from five sources (ECB, CBR, NBS, NBU, plus a USDT peg). Locally everything runs in Docker Compose — Postgres, migrations, web app, FX worker. For production there's a full AWS CDK stack with ECS Fargate, RDS, ALB + Cognito auth, and WAF. The whole thing is about 9 tables and a view — kept it flat on purpose so LLMs don't get confused.

If you're into security — please try to break it. My real financial data is in there. I can't do a formal bug bounty, I'm one person. But if you get my data, I'll buy you a pizza and a beer.

Happy to answer questions about the architecture. Feature requests welcome too.

We built a multi-port USB-C PD3.1 system that treats power delivery as a software-defined problem rather than fixed-function silicon.

This started as our internal R&D platform while developing a consumer charger. We were uncomfortable with the typical “the FAE handles the firmware, you just build the hardware” model that dominates the PD ecosystem. In that model, key behavior lives in vendor-controlled binaries, arbitration rules are opaque, and meaningful customization is either discouraged or impossible.

We wanted full ownership of the system — from power stage to protocol logic — and we wanted the ability to inspect, version, test, and evolve the charging algorithms ourselves. Instead of treating firmware as a thin configuration layer on top of fixed-function silicon, we designed the charger as a programmable system from the beginning.

Furthermore, we want to empower everyone.

So we redesigned the stack with a clean separation of concerns:

* ESP32-C3 (Wi-Fi + BLE) running open firmware * FPGA handling safety features and control plane management * 5× PD3.2 controllers (up to 140W per port capability)

The ESP32 chip offers:

* Local HTTP/JSON API * MQTT client * Prometheus exporter * OTA updates * Telemetry aggregation

Everything works locally; no cloud required (although cloud is available).

We approached this using software engineering discipline instead of traditional embedded shortcuts:

* Software defined, and software as an asset not a liability * Open Source firmware * Reviewable, testable modules * Exposed APIs instead of hidden vendor blobs

The idea is simple: if modern infrastructure is observable and programmable, power delivery should be too.

It’s fully solid-state, built with industrial components (Coilcraft inductors, Murata/Samsung MLCCs), and powered by an off-the-shelf Mean Well PSU for reliability and traceability.
