Ethereum/Solidity Engineer

I’m a final-year Computer Science student focused on Web3, smart contracts, and scalable backend systems. I recently completed a Blockchain Engineer Internship at Ziraat Technology (the innovation arm of Turkey’s largest bank), where I designed and implemented a staking-based governance/vault voting dApp with Solidity, Hardhat, Ethers.js, and a secure frontend integration.

Alongside that, I built Fennec AI DJ end-to-end — an AI-powered streaming platform that integrates Spotify Web Playback SDK with GPT-based command parsing and a hybrid recommendation engine. Earlier, at Mercedes-Benz R&D, I developed a Python automation toolchain (OpenPyXL, watchdog) that streamlined diagnostic workflows.

What I bring

Smart contract development: Solidity, Hardhat, Ethers.js/Web3.js, upgradeable patterns, RBAC, gas optimization
Full-stack & infra: TypeScript/Node.js, React, REST/WebSockets, Docker, PostgreSQL/MongoDB
Research & writing: clear technical docs, tutorials, and code walkthroughs (DevRel/Technical Writing friendly)

What I’m looking for

Smart Contract / Protocol Engineer, Security / Tooling (OpenZeppelin-style), or Developer Platform/DevRel roles in the Ethereum ecosystem
Remote (EU/US time zones), flexible hours, open to internships or junior roles where I can ship, learn, and contribute to public goods

Experience

Research and Development

Mercedes-Benz

2024 - 2024

During my internship with Mercedes' Diagnosis Team, I collaborated on developing diagnostic tools using CAN communication protocols and platforms such as Candela Studio, India Program, and CLIO Service. I worked on automating and improving diagnostic report accuracy, facilitating communication between systems to enhance vehicle data analysis and troubleshooting. Additionally, I developed a tool that automated the extraction of `.msg` email files into Excel format, integrating file locking mechanisms and real-time monitoring to improve data processing efficiency and enhance diagnostic processes across teams.

Machine Learning Intern

Lenora IT Technologies

2023 - 2023

Worked on end-to-end machine learning and data science workflows, involving data preprocessing, feature engineering, and model training using libraries such as Pandas, NumPy, Matplotlib, and scikit-learn. Built and evaluated supervised learning models (e.g., logistic regression, decision trees) to solve classification and regression problems. Focused on understanding model performance through cross-validation, accuracy metrics, and hyperparameter tuning. Additionally, contributed to data visualization dashboards to communicate results clearly and effectively.

Blockchain Engineer

Ziraat Technology

2021 - 2025

At Ziraat Technology, the innovation branch of Turkey’s largest bank, I contributed to the development of blockchain-based applications by writing and testing smart contracts using Solidity and Hardhat. My work focused on ERC standards, gas optimization, and smart contract security in a collaborative R&D environment. As part of my personal initiative, I designed and implemented a decentralized staking-based voting platform that explored governance mechanisms in scalable Web3 architectures. Additionally, I conducted research on upgradeable contract patterns, role-based access control, and simulated real-world DAO scenarios. This internship provided me with valuable hands-on experience in Web3 development, laying a strong foundation for my long-term career goals in decentralized technologies and the broader DeFi ecosystem.
