// 01 — ABOUT

Backend depth.
AI velocity.

Six years of backend engineering — the last three as Lead Software Engineer at Developers Studio. The core is Laravel and PHP: REST APIs, microservices, payment gateways, and the database architecture that fintech and blockchain products depend on.

I own projects end to end — discovery sessions, technical proposals, architecture decisions, sprint planning, code reviews, and post-launch support. I've led cross-functional teams, made the calls under pressure, and stayed accountable to clients and stakeholders directly.

The next chapter is production AI: LLM applications, RAG pipelines, autonomous agents, and automation workflows built to the same standard as a payment gateway — correct, observable, and actually shipped.

Multi-Currency Crypto Payment Gateway

// ARCHITECTURE

Architected a multi-currency crypto payment gateway from the ground up — supporting Bitcoin, Bitcoin Cash, Litecoin, and Ethereum — that serves 10,000+ monthly active users processing approximately one million transactions per month. Handles buy, sell, transfer, merchant checkout, and in-game purchase flows via Laravel REST APIs backed by a PostgreSQL ledger and Redis cache layer. Led the full lifecycle: technical proposals, system design, delivery, and post-launch support.

Quantitative Trading Pipeline

Python · NumPy · Pandas · MongoDB

300+Features engineered
25+ML targets
Real-timeBinance feed

// ARCHITECTURE

A Python-based quantitative trading pipeline that ingests real-time order and transaction data from Binance via MongoDB change streams. Applies feature engineering at scale — 300+ engineered features across 25+ ML targets — to train the models that drive automated trading decisions. NumPy and Pandas handle the numerical processing; trained models feed directly into the order execution system.

Automated Order Execution System

Python · Binance API · Algorithmic Trading

// ARCHITECTURE

Consumes model output signals from the quantitative pipeline to place live trades on Binance with dynamic stop-loss and take-profit boundaries. The execution engine translates model confidence into position sizing, manages open positions in real time, and closes them autonomously — completing the feedback loop from raw market data to live executed trade with no manual intervention.

Publication Platform Migration

Laravel · Vue.js · ViralWebbs

// ARCHITECTURE

Led the backend migration of a live publication platform at ViralWebbs from legacy core PHP to a modern Laravel REST API with a Vue.js frontend. Redesigned the database schema for query performance and scalability, then rebuilt the full author lifecycle: proofreading queues, publication workflows, sales tracking, and royalty management. Ran the org-wide rollout and onboarding workshops for the engineering team.
