Things I've built

Systems, interfaces, and experiments. The ones I keep coming back to live at the top.

Flagship

The Second Brain

A self-rewriting knowledge base Claude operates as a living second brain — sources rewrite existing pages, contradictions reconcile themselves, and scheduled agents maintain the vault while I sleep.

AX Platform

Frontend lead for Mevrik's AI-agent CX platform. I build the surfaces operators live in — inbox, CRM, embeddable widget, workflow canvas, agent studio, dashboards — wired to a live backend.

What I build at Mevrik

One omni-channel CX platform at Mevrik, many surfaces — plus the internal tools behind them. I can't show the product, so here's what I build, by type.

Omni-channel inbox

Chat, email and social in one triage-and-reply workspace.

AI voice call center

An AI-driven call center on Voximplant — voicebots, campaigns, live transcription, recording and call summaries.

In-app video calling

Embedded video calls with screen share and device control, via a third-party SDK.

Embeddable chat widget

A themeable widget that drops into any site via a one-line install script.

CRM & segment builder

Customer profiles, activity timelines and segments over server-paginated data.

Workflow canvas

An n8n-style node canvas for routing, auto-replies and automation rules.

AI agent studio

Where operators build, equip and deploy AI agents — identity, skills, knowledge, memory.

Analytics dashboards

Deflection, volume and CSAT — conversations turned into numbers.

Internal devtools

Utilities and internal apps that speed the team up — plus the deploy pipeline (Cloudflare, CI/CD, Docker) into devops.
