I designed and built Enigma end-to-end — a Solana on-chain trading agent platform that lets users assemble, backtest, and run automated trading strategies on memecoins and spot tokens with no code. I architected the system as a NestJS monorepo split into an API service and an execution engine, backed by MongoDB and Redis, and wrote the ZeroMQ stream pipeline that ingests on-chain trade events and routes them through real-time and simulation processors, so live trading and backtesting share one execution path.

On the engine side, I implemented the formula-driven strategy evaluator (custom operators, field-to-field comparisons, wallet-follow/wallet-avoid lists, take-profit, stop-loss, position-expiry, max-open-positions, and investment caps), the spot trading and manual-sell flows, and the failed-buy/sell rollback logic. I built the WebSocket gateway for live position updates, the analytics service, and a Next.js dashboard with strategy builder, leaderboard, PvP, referrals, a jackpot/rewards system, and Solana wallet auth. I also shipped the React Native companion app for monitoring strategies and live trades, and authored the integration test suite covering all 21 trade-lifecycle scenarios.

An AI-powered wealthtech platform that simplifies wealth management and delivers personalized experiences, insights, and financial opportunities. The platform enhances client relationships and provides real-time business insights, specifically for the Middle East and Northern Africa.

A decentralized, modular liquid restaking protocol allows users to maximize their yields without locking their liquid staking tokens (LSTs). By leveraging the EigenLayer, users can earn rewards in real time and use rTokens within decentralized finance (DeFi) protocols to further enhance their returns.

The client struggled with price calculations for various print materials, which is their main business activity. I developed an app to perform complex price calculations based on multiple factors:
• Square meters
• Labor costs
• Raw materials
• Fixed sizing
• Distinct product variations

I built a platform for managing salons and massage centers. It is used by customers to create reservations and appointments conveniently and by parlors to manage reservations and customer information efficiently.

Led the Angular upgrade effort, starting from AngularJS to Angular 17, by defining the strategy and creating a step-by-step plan to tackle the migration. I also ran Angular in a hybrid mode that allows parallel development of new features while maintaining the old ones.

I was part of the engineering team that built Spaspace, a multi-tenant SaaS for spas, wellness studios, and fitness clubs that consolidates bookings, memberships, staff scheduling, and point-of-sale into a single platform. I worked across the back end and the operator web dashboard, collaborating with product, design, and other engineers to ship features end-to-end.

On the back end, I contributed to the booking engine — room and therapist availability with conflict detection, recurring class schedules, waitlists, cancellation policies, and timezone-correct slot generation — and to the membership and package logic (credit balances, auto-renewal, freeze/pause, family plans). I worked on Stripe-backed payment flows, the notifications layer for confirmations and reminders, and parts of the multi-tenant data layer that isolates each venue's configuration while sharing the same code path.

On the front end, I built and maintained sections of the operator dashboard — the daily calendar, check-in, walk-in sales, and reporting views for revenue, occupancy, and retention — and contributed to the customer-facing booking flows. I also helped maintain the CI/CD pipeline and added analytics events feeding operator reports.
