Open to consulting and new roles

M. Enes Toy · Electrical & electronics engineer

I build systems that report back.

Industrial automation, elevator projects, then email infrastructure across 400+ domains. Now I’m building two products of my own: CherAmi and Muhento.

01Selected work

Two products I’m building now.

One moves the whole email engine onto your own server. The other keeps a group on one map after the signal is gone.

CherAmi

Self-hosted email platform

Own your email engine.

Cold outreach, newsletters and lifecycle automation from one platform on your own server: through your domains, your mailboxes and the sending providers you already use.

Muhento

Off-grid team map

No internet? Your team still sees each other.

An Android app for cycling and hiking groups. Small LoRa boards pass positions, quick messages and SOS from board to board without mobile data; anyone without a board joins the same map over the internet.

02About

“A system is only as good as what it reports back to you.”
Learned at Mikrodev in 2015, getting field data onto a SCADA screen. Still the habit I work by.

I’m an electrical and electronics engineer from Biga, Çanakkale. I started in industrial automation, getting field data onto SCADA screens, and later prepared and signed elevator installation projects as a licensed engineer.

From 2024 I worked on the email side of the internet for US companies, remotely: sending infrastructure for hundreds of domains, deliverability, and the monitoring that keeps it honest. Now I’m building two products of my own. Different worlds, same rule: a system that can’t tell you what’s happening isn’t finished.

  • In the field

    Field data on the headquarters screen

    Data from an off-grid system, read over Modbus and sent through a Wi-Fi-enabled PLC to the SCADA screen at headquarters.

    Modbus · PLC · SCADA

  • In the inbox

    400+ domains that report back

    SPF, DKIM and DMARC on every sending domain, reputation watched across Google Postmaster, Microsoft SNDS and seed tests, and an automated layer designed to pause a sender before its reputation drops.

    SPF · DKIM · DMARC

  • On the trail

    A group that still hears itself

    Positions, quick messages and SOS relayed from board to board over LoRa, so a cycling or hiking group stays on one map after the phones lose signal.
