Burak Erdoğan
AI & Cybersecurity Researcher
Computer Engineering student at Bahçeşehir University. Co-Founder at Çardak, Jr. Software Engineer at Kopernik TR, and Content Creator at FounderN. T3 Foundation Rising Star Scholar. I build ML models for phishing detection, Turkish NLP, and AI-based risk analysis — with national wins at TÜBİTAK, TEKNOFEST, and two ideathons.
What I Build
I'm a Computer Engineering student building at the intersection of AI and cybersecurity. I compete in national research competitions, lead product teams, write about the startup ecosystem, and ship software for real clients — all while still in university.
AI & Machine Learning: I train and fine-tune models for real-world tasks — Turkish sentiment analysis with BERTürk on 37K+ labeled reviews, hybrid phishing detection at 96.5% accuracy, and AI-parametric risk scoring for insurance. My models have been validated at national competitions and deployed in working products.
Cybersecurity Research: My focus is on applied security — building systems that catch threats before they reach users. CardGuard combines a machine learning classifier with AES-256 encryption, blockchain-secured local storage, and a MITM-resistant VPN module into a single browser extension. I approach security as an engineering problem, not just a checklist.
Product & Startup Work: Co-founded Çardak, a Super App for smart property management, born from winning the Emlak Konut Ideathon. Also led DASK+, an AI-parametric earthquake insurance product that placed 1st at the Neova Ideathon. I think in products, not just code — from ideation and pitching to building and shipping.
Writing & Engineering: As a content creator at FounderN, I've written 100+ articles on startups, venture capital, and emerging tech — applying SEO to grow real readership. On the engineering side, I freelance on full-stack web projects and automation for clients, and contribute to software development at Kopernik TR.

Contributing to software development projects as a Junior Software Engineer at Kopernik TR.
Developing custom software solutions for clients — including web applications, automation scripts, and tool integrations. Working across the full stack with a focus on clean, maintainable code and fast delivery.
Selected as a Rising Star Scholar by T3 Foundation — a prestigious program supporting Turkey's most promising young technology talent.
Selected for an exclusive AI training program among 31,700+ applicants. Intensive curriculum covering Python, Data Science, Machine Learning, and Deep Learning with hands-on experience in state-of-the-art algorithms.
Authored 100+ news articles and analyses covering the startup ecosystem, venture capital, and emerging technologies. Applied SEO strategies to grow organic readership and web traffic.
Achieved 1st Place at the Emlak Konut Ideathon, delivering the final pitch at Take Off Istanbul. Co-developed Çardak, a Super App connecting residents, administrators, and field personnel to digitize site management.
Achieved 1st Place among 100+ projects in the 3rd Neova Ideathon. Led end-to-end development of DASK+, an InsurTech platform providing earthquake insurance payouts within 72 hours via parametric triggering. Built ensemble ML model (XGBoost, LightGBM, Neural Network) achieving 99.76% accuracy (R²) on 10,000+ building datasets. Integrated SHA-256 blockchain and real-time Kandilli Observatory data.
Played an active role in establishing and executing the camp (64 participants, 56 schools, 25 provinces) with stakeholders including ASELSAN, TUSAŞ, HAVELSAN, ROKETSAN, and TÜBİTAK UZAY. Managed sponsorship files, presentations, and website security analysis. Selected alongside students from Turkey’s top 50 science high schools for training in aviation, defense, and space technologies.
Led 4-person high school team (HEZARTECH) to reach the Turkish finals in the TEKNOFEST 2024 NLP Competition, competing against university teams. Scraped and labeled 37,000+ Turkish customer reviews from Amazon, X (Twitter), and Şikayetvar. Fine-tuned BERTürk for sentiment classification (Positive/Negative/Neutral), achieving ~93% accuracy and F1 score.
Engineered CardGuard, a hybrid phishing-detection browser extension with 96.5% accuracy. Built multi-layered security with AES encryption, blockchain-secured local storage, and a built-in VPN module against MITM attacks. Presented at national finals.
Led Eco-Metrics, a data-driven sustainability project applying Edgar Dale's Cone of Experience via Web 2.0 tools. Achieved a measurable 36% reduction in weekly water consumption and 12% reduction in electricity usage among 431 students.
