Freelancer Overview

Software engineer with hands-on experience working with structured data, signal interpretation, and model evaluation through both personal AI/trading projects and production backend systems. I have built and iterated on Smart Money Concepts (SMC) and funding-rate arbitrage trading bots, where my work directly involved tasks analogous to AI training data preparation: defining clear labeling criteria for market structure and liquidity zones, validating model logic against backtested ground truth, and refining decision rules from observed performance. This required disciplined judgment when classifying ambiguous market signals — a skill that translates directly to high-quality data labeling and AI training feedback loops. Professionally, my backend development experience strengthens my ability to handle data at scale and ensure data quality. I build microservices in Java/Spring Boot, work with Kafka event streams, Redis caching, and PostgreSQL for structured persistence. I regularly perform root-cause analysis on production data through OpenSearch log querying, and I write complex SQL for data extraction and transformation. Across both domains I have developed strong attention to detail, comfort with iterative refinement, and the ability to follow precise specifications — the foundations of producing reliable AI training data.
