Writing technical specifications, architecting, implementing, and testing. Delivering value to customers while monitoring and evaluating KPIs.

Created "Document Signer Multifactor Authentication" enabling our customers to identify via their Mobile devices in the electronic signing process. This feature increased the security and validity of our electronic signatures, generated trust among our customers, and helped sales to onboard enterprise customers.

Created "Automated Bulk Sending", providing our customers means to send large numbers of documents, automate their business processes, reduce repetitive work, and save time. This feature was a high-level sales request, resulting in a fantastic early adoption rate, onboarding of large customers, and side income enough to finance a new team member.

Migrated complete eversign user-base to our new email delivery servers. Along the way, we resolved legacy issues and introduced missing technical processes for handling bounced emails and fraud complaints. The result was optimal email delivery with 30-40% reduced cost as a bonus delivery.

Together with CFO designed and introduced a minimalistic in-house BI system. Desired and accomplished result was to measure various KPIs such as MRR, YRR, signup sources, daily sales statistics, integrations consumption sources, customer lifetime values, customer subscriptions lifetimes, etc. KPIs were then incorporated into daily processes, and adopted by sales and customer success teams; this resulted in cross-team knowledge share and increased general awareness of the possibilities we have for data-driven decisions.
