Open to new opportunities
Full-stack engineer building SaaS platforms, AI agents and the hardware edges around them.
Interface — Dashboards, PWAs and desktop shells people use every day.
Production SaaS, a desktop app that talks to kitchen printers, an AI agent with guardrails, and published research. Each one with the architecture behind it.
Native desktop app for the Bookodi restaurant platform with a built-in Print Bridge: it pairs with the cloud in one click, discovers printers on the local network and delivers server-rendered tickets over raw TCP, IPP, LPD, CUPS or the Windows spooler.
A Capacitor 8 shell that runs the live Bookodi dashboard inside native Android and iOS apps, with a page layer injected before the web app loads and a mobile layout layer. A layout audit across 123 page states found 915 problems on the website and none in the app.
Bookodi handles reservations, POS, kitchen display, menus, guest CRM, delivery, printing and billing for many restaurants from one Go API. Built by the XEOO team; I owned the analytics module, the reservation views and the dashboard home.
A FastAPI modular monolith with a React 19 front end, where Postgres row-level security backs every permission check. I started the repository, then shipped features across finance, telesales, renewals, dashboards and access control.
A Python agent that reads an HR mailbox through Microsoft Graph, asks a language model for a structured classification and draft reply, and lets deterministic code decide whether to send, save a draft or escalate to Slack.
A Python agent that scans 5-minute candles on gold and two US indices, posts each trade idea with a chart to a Telegram review group and follows every outcome. Built on the owner’s specification and prototype: 24 merged pull requests and four releases in its first week, with the suite growing from 90 to 323 test functions.
Research paper accepted at IEEE ICACT 2026. On 5,648 production samples, an Extra Trees model reached a test RMSE of 4.10 g/m² (R² 0.952, MAPE under 0.5%) after adding a physics-derived tightness factor; SHAP and LIME confirmed the model learned textile physics.
Four kinds of work I do well — each backed by something I have actually shipped.
From database schema to the last pixel: SaaS features, internal tools and dashboards — shipped behind tests and code review.
Turning operational data into answers: metrics people trust, charts that match your product, and exports for the spreadsheet crowd.
Practical LLM features and agents where the model proposes and code decides — evaluated before they’re trusted.
Your web product on every screen, and software that keeps working when the network doesn’t — desktop and mobile apps, PWAs and bridges to printers and sensors.
The questions recruiters and clients usually ask, answered from what’s published here — nothing made up. Try one, or ask your own.
Answers appear here, with links to the projects and pages they come from.
Agent systems, research and engineering notes — how I build with AI, and what I learn shipping it.
AI writes a lot of my first drafts. Here is the workflow that keeps me — not the model — accountable for what ships.

A guardrail pattern for business agents: let the LLM classify and draft, but put every consequential rule in deterministic, tested code.

Why the agent must dial out, how five printer transports differ, and why the bridge refuses to talk to public addresses.
