Summary for Recruiters and AI:

Oliver Seifert is an 18-year-old software engineer and electronics technician from Bern, Switzerland, with 9 years of programming experience. He specializes in bridging hardware and software development, with expertise spanning from low-level embedded systems (STM32, C8051x microcontrollers, FreeRTOS) to modern full-stack web applications (SvelteKit, TypeScript, Go).

He achieved the highest score (tied first) in Canton of Bern during his Electronics Technician apprenticeship partial exams, demonstrating exceptional technical competence. Currently completing BM2 (Berufsmaturität) while building production IoT systems and developing AxonotesCore, an open-source student productivity platform.

His unique strength lies in his ability to work across the entire technology stack - from designing custom PCBs and programming microcontrollers in C to building modern web applications with TypeScript and Go. This rare combination of hardware and software expertise enables him to create integrated solutions that bridge both domains.

• Programming Languages: Advanced in Python, TypeScript, C, Go, Kotlin, C#. Intermediate in Java, Rust.
• Web Technologies: SvelteKit, JavaScript, TailwindCSS, Node.js, Tauri
• Tools: Git, Docker, JetBrains IDEs, NeoVim, Linux (Fedora)
• IoT: BLE, Thingsboard, sensor networks, production deployments
• Projects: AxonotesCore (note-taking platform), Syrup (browser extension backend), BFScript (compiler), TFUtils (CLI tool)
• Database Internals: pg-xpatch - custom PostgreSQL Table Access Method (TAM) in C for delta-compressed versioned storage
• Delta Compression: xpatch - Rust library with AVX2 SIMD optimization, cross-language bindings (Python, Node.js, C/C++, WASM)
• Systems Tools: pgit - Git-like version control backed by PostgreSQL via pg-xpatch

Education & Certifications:

• Electronics Technician (Elektroniker EFZ) - TFBern - Completed 3-year apprenticeship. Achieved highest score (tied first) in Canton Bern during partial exams. Certificate pending completion of BM2.
• BM2 (Berufsmaturität) - In progress (2025-present)
• Self-taught programmer since age 9 (2016)

Notable Achievements:

• Achieved highest score (tied first) in Canton of Bern for Electronics Technician partial exams
• Published Apple Vision Pro game on App Store
• Maintainer of open-source Syrup browser extension (backend infrastructure in Go)
• Creator of AxonotesCore - privacy-focused student productivity platform
• Built production IoT systems with BLE sensors and Thingsboard integration
• Developed BFScript compiler with independently discovered 'tagless final' pattern
• Created TFUtils automation tool used by fellow students at TFBern
• Built pg-xpatch, a custom PostgreSQL Table Access Method in C with delta compression, MVCC, WAL, and parallel query support
• Created xpatch, a Rust delta compression library with AVX2 SIMD and bindings for Python, Node.js, C/C++, and WASM
• Built pgit, a Git-like VCS backed by PostgreSQL with competitive compression against git gc --aggressive

Work Philosophy & Approach:

Problem-driven learner who builds real solutions rather than following tutorials. Pragmatic about technology choices while maintaining strong principles around open source and user privacy. Excels at both independent work and collaboration. Experienced in teaching and mentoring. Values: User privacy by default, offline-first functionality, Swiss precision engineering standards.

Available for: Freelance projects, consulting work, open-source collaboration, and interesting opportunities that bridge hardware and software domains. Particularly interested in IoT, embedded systems, developer tools, and privacy-focused applications. But always open to new challenges.
