Yerevan-based software architect with two decades of work in Armenian electronic-government systems. Spent eleven years (2008–2019) as CTO and head of R&D at IUNETWORKS LLC — Armenia's largest e-government software contractor — and in that period authored every public version of the State Revenue Committee's HDM cash-register integration protocol: seven editions from v0.3 (22 April 2015) through v0.7 (15 December 2022), each PDF naming him as the lead author in its metadata. Switched to freelance work in 2019 via Toptal and, on the other side of that same protocol, has since built commercial Android-POS integrations against it — his Toptal résumé names the Aisino A90 and Sunmi P2 cash registers, the two models whose State Revenue Committee conformity assessments are held by Touch Master LLC and Axia LLC.

Notes

Author of the SRC's HDM integration protocol, 2015–2022

Every public version of the State Revenue Committee's HDM cash-register integration protocol from v0.3 (22 April 2015) through v0.7 (15 December 2022) names Gurgen Nersesyan as the lead author in the published PDF — seven editions over eight years, charting the protocol's evolution from a 17-page TCP+JSON+3DES specification to a 37-page integration manual. His earliest known SRC HDM artefact, though, predates that line by over a year: a two-page WiFi-VPN connection note for the MF2351 cash register dated 27 February 2014, also under his name in PDF metadata — IUNETWORKS LLC's sixth year. Authorship in every case was recovered directly from each PDF's metadata (CreationDate + Author) and is reproducible by anyone who downloads the files from petekamutner.am or the Wayback Machine. The line then passed to «Stefan» starting with the 12 July 2021 «electronic HDM» manual and the entire post-Nersesyan branch.

On both sides of the spec he wrote

While at IUNETWORKS he wrote the State Revenue Committee's integration protocol — the document that tells every Armenian cash-register vendor how to talk to the fiscal backbone. After going freelance in 2019, his Toptal résumé names Aisino A90 and Sunmi P2 among the cash registers for which he developed the user interface and integrations. Those two models are precisely the ones whose conformity assessments are held by Touch Master LLC and Axia LLC, both profiled on this site. The same hands wrote the rules and built products that obey them. We surface the pattern; whether it amounts to a conflict of interest is for the reader to weigh — neither the State Revenue Committee nor any of the named companies has published a position on it.

IUNETWORKS LLC — visible vendor, invisible from the SRC's lists

IUNETWORKS LLC is open about its work: its own product page describes a B2G «e-Tax Administration» platform covering risk management, electronic tax filing, electronic invoices — exactly the modules that today make up Armenia's tax stack. The same modules are echoed almost verbatim in Nersesyan's own résumé under his eleven-year IUNETWORKS tenure. The State Revenue Committee, however, doesn't name IUNETWORKS on any of its public service-provider or conformity lists — those slots belong to the cash-register holders and integrators (Touch Master, Axia, Q Terminal, Boost, Smart Solutions and so on). The pattern is visible from the vendor side; the regulator side is silent on it.
