Glean AI is an accounts payable (AP) solution that empowers finance teams with spend intelligence and streamlined workflows for their AP needs, including invoice processing, payments, approval workflows, and general ledger integrations.

I joined the company during a period of growth, as the team was expanding and the product evolving. Initially, I was responsible for envisioning and developing the new Payments product, with support for multiple payments providers. This was a valuable opportunity to gain deep insights into the payments ecosystem and apply my knowledge in how to seamlessly integrate with various providers.

Another major initiative was breaking down the monolithic application into smaller services, improving developer velocity and making the codebase more maintainable. The challenge was to align this technical shift with business needs, ensuring that we didn't slow down product development.

Additionally, I worked closely with the Customer Success team, implementing monitoring and alerting systems to proactively address issues that our customers encountered.

Key Achievements:

• Developed the Payments product, integrating with multiple payment providers to support ACH, Wire, and Check payments.
• Integrated with several General Ledger services, including QuickBooks Online (QBO), Netsuite, and Xero.
• Refactored the monolithic application into smaller services, enhancing developer velocity and maintainability of the codebase.
• Collaborated with the Customer Success team to implement monitoring and alerting systems, ensuring swift identification and resolution of customer issues.

Nodis was a platform that connected small retailers to digital marketplaces, enabling them to sell their products online to a broader audience.

I joined the company in its early stages and had the experience of building a product from scratch. This allowed me to engage in the entire product lifecycle—from ideation to launch and maintenance. I was involved in architectural decisions and responsible for developing monitoring and alerting systems.

The engineering team's vision was to build a scalable and reliable product while keeping technical debt to a minimum. This was achieved by adhering to strict standards for code quality, test coverage, and best practices. I also had the opportunity to mentor new developers, contributing to the team’s culture and technical growth.

Key Achievements:

• Developed an ingestion system for product data, refining our catalog and improving search engine quality. The catalog contained millions of products, updated daily.
• Integrated with multiple marketplaces (Amazon, B2W, Mercado Livre, Magalu) in a decoupled way, making it easy to scale and add new marketplaces.
• Built core functionality using RabbitMQ and an event-driven architecture, allowing us to scale the system and add new components without disrupting existing ones.

Walltime was a cryptocurrency exchange platform that aimed to provide a secure and user-friendly way to buy and sell Bitcoin.

At Walltime, I began my journey in the tech industry, collaborating with all departments, including customer support, operations, and software development. This experience helped me adopt a product-first mindset and effectively translate business demands into actionable requirements.

As a company in the crypto segment, Walltime prioritized information security, prompting me to integrate InfoSec best practices into my workflow.

Key Achievements:
