À propos de Thaïs

Hi, I'm Thaïs 👋

I am a 𝗦𝗲𝗻𝗶𝗼𝗿 𝗣𝗿𝗼𝗱𝘂𝗰𝘁 𝗠𝗮𝗻𝗮𝗴𝗲𝗿 with an engineering background and 𝟭𝟬+ 𝘆𝗲𝗮𝗿𝘀 𝗼𝗳 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 helping businesses build better products, scale efficiently, optimise workflows, and drive impactful growth across industries like payments, event tech, hospitality, and e-commerce.

✅ What I've done so far:

→ Worked with teams of up to 11 engineers, delivering back-end and front-end solutions for a marketplace with 30M+ monthly visitors.

→ Scaled event payment solutions handling 20M+ transactions, using strategic prioritisation, user-centric design, and process automation.

Defined product vision and strategy from scratch, setting North Star metrics and delivering the first roadmaps to align teams and accelerate growth.

Reduced Ops team workload by 93% on a major task, replacing manual processes with automated, AI-assisted validations.

🎯 Why work with me?

Freelance agility & adaptability: With experience across diverse industries, team sizes and growth stages, I integrate seamlessly with your team, adapt quickly to your context, and drive change where it matters most.

Clarity & alignment: I map out processes and user flows to align teams and make sure we focus on the right outcomes and initiatives, with clear communication every step of the way.

Pragmatic problem-solving: I turn complex challenges into actionable plans, using data and collaboration to deliver measurable, incremental results.

Proven results: From optimising high-traffic marketplaces to automating user onboarding processes, I deliver high-impact outcomes, even under tight deadlines.

➡️ Let’s work together!

    ✅ Improved payment-to-delivery conversion by optimising the transaction cancellation process:
    → Reworked cancellation reasons to reduce ambiguity and enable data-driven prioritisation for future improvements.
    → Automated listing actions following cancellation (ex: pausing ads for unavailable items, removing the delivery option if cancelled for that reason), eliminating future cancellations for these cases.

    ✅ Strengthened platform trust and reliability:
    → Launched automated 1-star seller ratings for avoidable cancellations, rolling out gradually to monitor customer support feedback.
    → Adapted cancellation possibilities to prevent fraudulent patterns.

    ✅ Led new home delivery feature from discovery to MVP in 6 months, ensuring seamless integration despite partial coverage constraints, requiring an adapted dynamic purchase flow.

    ✅ Automated incident communication using user segmentation and dynamic alerting, ensuring the right message reached the right users.

    Reduced Ops team workload on onboarding by 93% by leading a data-driven optimisation approach with systematic A/B testing.

    This resulted in:
    → Replacing 15-minute onboarding calls with 1-minute AI-assisted validations, using welcome videos, in-app questions, skill questionnaires, and video interviews to filter candidates upfront.
    → Accelerating the process by 85%, enabling talents' profiles to be validated or declined in just 1 day instead of 1 week.
    → Not only maintaining talent standards but also improving overall talent pool quality as a result.

    ✅ Collaborated with sales and operational teams to enhance clients classification and talent experience data, to improve the matching algorithm accuracy; identified key changes and product impacts to reach this goal.

    ✅ Initiated product research to enhance feedback mechanisms, ensuring continuous quality measurement and improvement.

    ✅ Contributed to the design of the business homepage on the app, focusing on user experience enhancements.

Avis laissé le 10.02.2026

J’ai travaillé avec Thais pendant 8 mois au sein de mon équipe et tout s’est très bien passé. Elle a pris en main des sujets complexes et exposés avec beaucoup d’efficacité, en les cadrant rapidement et en les menant à bien jusqu’à la livraison. Très à l’aise avec la data, elle s’appuie toujours sur des faits pour orienter ses décisions et faire avancer les sujets. C’est aussi quelqu’un de très agréable avec qui travailler : claire dans sa communication, positive, toujours avec le sourire, et appréciée par toute l’équipe. Je la recommande sans hésiter pour des missions de Product Management !
