Fintech & payments
Ledgers that balance to the penny, idempotent payment flows, reconciliation, and payout state machines built for real money and audits.
I don't just build apps. I build the systems apps are built on — payment rails and ledgers, AI agent platforms, and full-stack product that ships. This whole page is a single hand-written file: no frameworks, no images, no shortcuts — every pixel, chart, and animation drawn in code.
01 — Live product · not a mockup
A pocket AI that knows me, rendered on a phone modeled in pure CSS 3D — no image files, no WebGL crutch. Drag it to spin it. The conversation on screen is running live, right now, in your browser.
02 — Systems, live
Three product surfaces I design and build — payments infrastructure, an algorithmic trading engine, and an AI-agent control plane. Every number carries context; every scale is honest. Telemetry below is simulated for the demo — the engineering is real.

Mark price with the engine's conviction band. Entries flagged where score > threshold.
Classifier output, updated each bar.
Live message flow between agents. Pulse = active hop.
Tasks/min with model-detected anomaly band.
Throughput dipped 14% at 14:20 — correlates with a tool-timeout spike on agent‑07. Suggested next step: raise its retry budget and re-route to the warm pool.
03 — What I build
From the database schema to the last easing curve — I own the whole stack and obsess over the seams between the layers.
Ledgers that balance to the penny, idempotent payment flows, reconciliation, and payout state machines built for real money and audits.
Multi-agent orchestration, RAG pipelines, tool-use, and guardrailed control planes — AI systems that are observable, explainable, and safe.
React/TypeScript front ends, Node & Rust services, and the interaction craft that makes a product feel inevitable — like this page.
