About
One engineer.
Full accountability.
CrovnCRM is led by Arsalan Sunehri —founder & lead ai/full-stack engineer based in Ras Al Khaimah, United Arab Emirates. No account managers, no hand-offs, no juniors on your project: the person you talk to is the person who designs the schema, writes the code, and deploys it.
Enterprise finance & audit
Domain software where correctness is non-negotiable: double-entry ledgers, approval workflows, append-only audit trails, and tamper-evident reporting.

AI & automation engineering
Workflow automation, document pipelines and LLM-powered tooling that removes the manual work between your systems.

DevOps & delivery
Your own infrastructure, not ours. CI/CD pipelines, VPS deployments, and documented handover — you own the code and the keys.
