Our Team
Engineering Depth,
Not Headcount.
Our team has built carrier-grade telecom systems, 50K-line Rust codebases, and sovereign payment infrastructure. We solve hard problems because we have done it before.
Founder & Leadership
Lutfar Rahman (Nirjhar)
CEO & Managing Director
A 26-year journey from founding SNIPro in 2000 to directing 31+ production products across KaritKarma and LoneSock Consultancy. Nirjhar is the architect behind the entire KaritKarma ecosystem — from identity infrastructure (Wenme) and authorization (Darwan) to carrier-grade voice systems (BitsPath Voice) and sovereign payment networks (IntraPay).
As an APNIC member operating ASN 64005 with BGP peering and own IP blocks, Nirjhar brings infrastructure-level thinking to every project. This is not theoretical — it is the operational backbone serving production traffic today.
His expertise spans systems architecture, platform design, and telecom infrastructure. Every client engagement at LoneSock draws on patterns validated across this portfolio.
