A client once told me: "I know exactly how much I sold this month. I just don't know until next month."
That sentence is why we built the Smart Inventory & Ledger System.
When stock, sales and accounts live in separate places, every decision runs late. You reorder after the shelf is empty. You chase dues you didn't know were overdue. You find out an item was your best seller when it's already out of stock.
What the system does instead:
• Flags low stock early and drafts the purchase order with AI
• Posts every purchase and sale to the ledger automatically, with no re-typing
• Answers plain-English questions about your sales, customers and stock in seconds
• Puts sales, purchases, dues and payables on one dashboard
The outcome: owners spend less time reconciling and more time growing. Fewer missed orders, cleaner books, faster calls.
Watch the 15-second demo below. It goes from a low-stock alert to a restocked item, an updated ledger and an AI sales summary.

Alma Collective, a fitness booking platform for the Greek market, was stuck: half-built by a previous developer, unstable, and nowhere near launch-ready.
I took over the codebase, stabilized it, completed the missing core flows, and carried it to public launch across web and mobile (React Native).
What shipped:
User app: discover and filter classes (yoga, Pilates, dance), book and pay per session, QR check-in on arrival
Partner portal: venue listings, class scheduling, payouts, subscriptions
Payments: Stripe with Apple Pay and Google Pay, pay-as-you-go and subscriptions

BioSonic is an AI-driven platform for analyzing bat acoustics used by research teams across Europe. I built the full web portal from scratch and transformed it into a high-performance, scalable system capable of handling multi-terabyte datasets.
My role covered full-stack development, infrastructure optimization, and performance engineering. I optimized Supabase RPCs and SQL queries, achieving 5× faster data retrieval and 240% faster file loading, while stabilizing AWS services to eliminate downtime. I also enhanced the SQS-based job distribution system for parallel data processing and implemented EC2 monitoring tools for better reliability and proactive scaling.
This project showcases my ability to own complex systems end-to-end, improve large-scale performance, and deliver production-ready solutions under tight deadlines, all while maintaining clear communication and client satisfaction.

Social Followers is an e-commerce platform built to sell social media marketing packages for Instagram, TikTok, YouTube, and Facebook. The business needed a fast, low-risk way to validate demand and start taking orders before investing in full supplier automation. I delivered a focused first release with a service catalog, guest and registered-user carts, price-locked checkout, Stripe payments, order tracking, an admin fulfillment dashboard, wallet refunds, and queued email notifications. The system is also structured for future integration with external service providers.
I built the platform with Next.js, React, TypeScript, PostgreSQL, Drizzle ORM, Stripe, Tailwind CSS, and Jest. Verified Stripe webhooks are the source of truth for payments, while database transactions and idempotency controls prevent duplicate payment attempts and orders. Item-level state management supports partial fulfillment and automatic wallet credits when a service fails. I also implemented JWT authentication, role-based access, email verification, password recovery, rate limiting, localization, responsive interfaces, and automated tests for the main purchase flow and edge cases.
