About AI Code Invest
AI Code Invest is a personal blog covering the intersection of three topics I work with daily: artificial intelligence and machine learning, software and data engineering, and long-term investing in U.S. markets. Every post is written to be the article I wish existed when I first researched the topic—practical, hands-on, and grounded in real implementation.
Who writes here
Hi, I’m kongastral. I’m a software engineer with a background in machine learning systems, data pipelines, and quantitative investing. I started this blog because I kept writing the same explanations and notes for myself across projects—on Gaussian Processes, on Kafka pipelines, on options Greeks, on portfolio construction, and figured someone else might find them useful too.
Areas I write about
- Applied AI/ML: anomaly detection (Deep SVDD, OCSVM), domain adaptation (DANN), self-supervised and semi-supervised learning, Gaussian Processes, time-series forecasting
- Software & data engineering: Apache Kafka, Apache Airflow, Debezium CDC, dbt, Docker, Python, FastAPI, time-series databases
- Investing: U.S. stocks, ETFs, options, dividend investing, dollar-cost averaging, tax-efficient strategies, portfolio construction, behavioral finance
Editorial process and AI disclosure
I want to be transparent about how content is produced here, because trust is the most important thing a writer has.
What this means in practice
- Code examples are tested. If a Python snippet appears in a post, it has been run.
- Math and formulas are verified. Equations are cross-checked against original papers and textbooks.
- Sources are real. External links point to original papers, official documentation, or recognized references, no hallucinated citations.
- Figures are original. SVG diagrams are produced specifically for each post to illustrate the concept being explained.
- Updates happen. When I find an error or when content becomes outdated, I update the post and note the modification date.
