2020 - 2024 • CEO & Founder

Founded and launched a B2B contract management platform in just 5 months

B2B contracting is painful. Companies are using more than five tools to create, negotiate, and sign just one contract. This costs companies valuable time and is highly inefficient, leading to long sales cycles, lost revenue, increased costs, and no scalability.

Using Swiftsign, every team manages contracts faster, more simply, and all in one place.

Series A
2022 - Today • Founding Product Designer

Building a bot detection and analytics software to reduce your ad spent

Nearly half of online traffic originates from bots, and since AI, these numbers have risen unpredictably. This is costing companies and marketers data accessibility, leading to highly ineffective decisions, lost revenue, and increased costs.

Using fraud0, fraudulent traffic can be identified and blocked from all channels to help marketers make clear decisions again.

Tucan Ai
2019-2020 • Founding Product Designer

Led the design of three product pivots based on intensive research in the audio transcription field

Professionals spend on average 6-8 hours in total preparing and correcting a transcript of a one hour interview. This manual process is highly inefficient, costing companies valuable time, leading to high costs and lost revenue.

2018 • Founding Product Designer

Built my first end-to-end MVP within 4 months for a current industry leader
