SignNow API dashboard on MacBook
SignNow API-first experience2023 - PRESENTE-SIGNATURE

SignNow is a e-signature platform with 20 million users worldwide that lets individuals and teams securely sign, send, and manage documents online from any device.

As a product designer on API, I redesigned the onboarding flow so developers can move from first request to a successful embedded signing session in minutes, guided by clear examples. The result is an e-signature API that feels intuitive for the people use it everyday to optimise their workflows.

SignNow Integrations preview
SignNow Integrations2023 - PRESENTE-SIGNATUREINTEGRATIONS

SignNow provides many native integrations. As a Product Designer, I led the end‑to‑end redesign of SignNow’s integrations experience, aligning it with the core product and modernizing the visual and interaction patterns.

I focused on making complex integrations easy to understand and configure for both technical and non‑technical users, covering platforms like Salesforce, HubSpot, Google Workspace, Microsoft 365. After shipping the new experience, I created an improvement concept that is planned for a future product release.

ABOUT ME

I'm Anastasia, product designer with marketing background

I've started my career in marketing and user acquisition before moving to design. That means I think about funnels, conversion, and business metrics in addition to user flows and interaction patterns.

I've worked across the full product lifecycle — from early discovery, user interviews, and competitive analysis to wireframes, prototypes, design systems, and post-launch optimization. I've designed for both B2B platforms (API developer onboarding, CRM integrations, SaaS dashboards) and B2C products (health & wellness apps, e-commerce).
