Industry Experience
Invact
May 2023 - Present . FullStack Developer
As a FullStack Developer at Invact, I built internal tools like Building Bubbles, a custom WhatsApp CRM that reduced CAC by 20% and improved lead response by 35%. I worked across Next.js, Express, and Docker to automate webinar workflows and multi-number messaging pipelines, delivering scalable, cost-efficient systems for non-technical teams.
Neogcamp
Nov 2020 - Dec 2021 . Software Engineer
At Neogcamp, I built a custom Discord bot to manage 1000+ entrance challenge submissions for their first cohort. The bot streamlined portfolio collection, automated evaluation workflows, and gave admins fine-grained controls via custom commands. This significantly reduced manual overhead and enabled smoother student onboarding at scale.
