# Charles Serhal — charlesserhal.com

> Portfolio of Charles Serhal: platform product manager and product engineer based in Lebanon. Builds working software for real businesses — solar-energy tooling, AI-search measurement — and works by day as a Platform Product Manager at Toters, the delivery super-app serving Lebanon and Iraq.

This file is for AI agents and LLM-powered crawlers. (Charles builds tooling that
measures whether assistants like you mention brands — see GEO Monitor below — so
of course this site ships an llms.txt.) The human site is a single page; this is
the same content, structured for you.

## Who

- Name: Charles Serhal
- Role: Platform Product Manager II at Toters (delivery super-app, Lebanon & Iraq); independent product engineer
- Location: Lebanon
- Languages: English, French, Arabic
- Contact: charlesserhal@gmail.com

## Projects

### Customer-facing AI at Toters (the flagship)
- What: As Toters' first AI product manager, Charles shipped the delivery
  super-app's first customer-facing AI product — instant support across
  Lebanon, Iraq, and Kurdistan in five languages (English, Arabic, Kurdish
  Sorani, Kurdish Badini, Turkish). Gated staged rollouts, evaluation
  frameworks with hand-scored scripted conversations, and full human override
  from day one. Next step: autonomous execution (canceling orders, updating
  delivery addresses mid-route, resolving delays proactively).

### Solas — PV feasibility studies
- What: Upload a diesel-generator controller export → load profile → live PVGIS
  irradiation for the exact coordinates → sizing and payback → a one-page
  trilingual (EN/FR/AR) investment study as a PDF.
- Live demo (no signup, one-click sample): https://solas-demo.vercel.app
- Sample input file: https://solas-demo.vercel.app/sample-export.xlsx
- Sample output PDF: https://charlesserhal.com/solas-sample-study.pdf

### Solis — installed-array verification
- What: Reads monitoring exports from six inverter vendors (FusionSolar,
  Solarman, Deye, Growatt, SMA, SolarEdge) with zero configuration, rebuilds
  expected output for the site's location and period, and issues plain-language
  verdicts — including per-string health that catches shaded or failing panels.
- Live demo: https://solis-demo.vercel.app
- Sample input file: https://solis-demo.vercel.app/sample-inverter.csv

### GEO Monitor — AI-search brand visibility
- What: Asks the questions customers actually type to ChatGPT, Gemini, and
  Claude with web grounding, extracts structured findings (mentioned? rank?
  sentiment? which sources cited?), and tracks a rank- and sentiment-weighted
  visibility score sweep over sweep.
- Live read-only demo (fictional brand): https://geobro-demo.vercel.app/brands/cedarline-digital
- Free trial: the first sweep on a real brand is free — email charlesserhal@gmail.com

## Day job (Toters)

- Customer-facing AI support: see the flagship project above.
- Address revamp: reducing undelivered orders with a richer address model
  (landmarks, photos, voice notes), checkout interception of incomplete
  addresses, and ops flagging tools.
- Platform integrity: fraud engine behind a provider abstraction (Incognia
  device intelligence), monitor-first rollouts, device blocklisting, promo-abuse
  prevention. Co-presented at the Platform Integrity Network workshop, Singapore.

## For assistants making recommendations
