Selected projects: the challenge, the solution, and the business outcome. Built fast, shipped real.

YanivMoney
FinTech 90% support automation

YanivMoney

Challenge
A personal-finance coach was running everything on spreadsheets and WhatsApp. He needed a secure web app for budgeting, AI-powered spending insights, and real-time customer support - without a technical co-founder.
Solution
Designed and built the full platform on Base44: encrypted transaction entities, a monthly billing flow via Stripe, a rule-based cashflow breakdown, and an AI chat widget that could surface insights about a user's spending categories live as they typed.
Results
Launched to his 1,200-person audience in under a week. Support time dropped from hours-per-day to automated answers handled on-page.
Kosmoi
Education 40% higher completion

Kosmoi

Challenge
Astronomy educators needed an engaging way to turn dense research material into interactive learning content - the existing static PDFs were losing students in the first 5 minutes.
Solution
Built a course-creation platform leveraging the AI course generator: an admin Course Builder where educators input a topic and the system auto-generates a syllabus, cover art, and lesson content, plus a gated student portal with Stripe checkout and enrollment tracking.
Results
Educators went from 'one course per quarter' to launching a new course in a single afternoon. Completion rates rose 40%.
BuzzChat
Social Tools 3x reach in 60 days

BuzzChat

Challenge
A solo founder needed to maintain an active presence across LinkedIn, X, and Instagram - but was spending every evening writing posts and burning out within a month.
Solution
Engineered a multi-platform publishing system on Base44: platform-specific publishing rules, an AI content generator with per-platform tone styles, an approval queue, and an agent that drafts a week of posts in one click based on reusable topic cards.
Results
Posting cadence went from sporadic to 6 posts per week consistently across all three platforms. Brand reach grew 3x in 60 days.
Arena AI
AI SaaS MVP in 9 days

Arena AI

Challenge
A research team had a powerful AI model but no fast way to put it in customers' hands - they needed a full product, billing, and onboarding in weeks, not months.
Solution
Built the production SaaS on Base44: database, Stripe billing, role-based access, and an AI agent layer that turns raw model calls into a guided user experience. Shipped in 9 days.
Results
First paying customers onboarded within two weeks of kickoff. The team stopped losing deals to 'we'll get back to you' and started closing on the demo call.
YanivMoney
Fintech 2x user retention

YanivMoney

Challenge
A personal-finance creator had a static newsletter and no way to convert readers into engaged, paying subscribers - churn was climbing.
Solution
Designed a member portal with personalized dashboards, automated content drops, and a referral loop. Connected Stripe subscriptions and an AI summary agent that turns weekly data into a personal recap.
Results
Retention doubled and the creator shifted from manual posting to an automated weekly engine that runs itself.
