I am Ata Can YAYMACI, a Full-Stack Software Expert and open-source developer passionate about building robust enterprise systems, autonomous AI agent architectures, and hardware-software integration solutions.
My technical focus bridges high-level web & cloud architectures with AI Agent Systems (LangChain, RAG, Prompt Engineering) and IoT ecosystems (ESP32, Microcontrollers, Meshtastic). I continuously push technological boundaries by designing modular, clean, and scalable solutions that bridge software and hardware.
💡 Engineering Mindset: Clean code, minimalist design, and scalable architecture.
|
Designing autonomous AI agent workflows, retrieval-augmented generation (RAG) pipelines, system prompt architecture, and enterprise AI security audit frameworks. |
Building scalable web platforms, high-throughput backend APIs, microservices, dynamic content aggregators, and resilient database synchronization engines. |
|
Connecting physical hardware with enterprise software through custom microcontrollers, IoT mesh networking (Meshtastic), RESTful hardware adapters, and C++/Python APIs. |
Developing automated data extraction services, multi-source scraping frameworks, concurrent market research search clients, and CLI developer productivity tools. |
Note: The list below is dynamically updated via a custom GitHub Actions automation (
update_latest_projects.py). It fetches my most recent and active repositories to keep this portfolio fresh!
- GitRadar — GitRadar is an open-source Command Line Interface (CLI) tool designed for software developers, founders, and open-source creators.
- hesapli-izin — Hesaplı İzin, Türkiye'de çalışanlar için geliştirilmiş, resmî tatilleri, dinî bayramları (Arefeler dahil) ve hafta sonlarını yıllık izinlerle akıllıca birleştirerek minimum izin günü harcayarak maksimum kesintisiz tatil elde etmeyi sağlayan, %100 çevrimdışı çalışan bir Progressive Web App (PWA) uygulamasıdır.
- WhoDisGit — GitHub unfollowers detector and profile analytics dashboard built with React, TypeScript, and Tailwind CSS
- RubberOtterWeb — A modern, responsive Progressive Web Application (PWA) built with Vite, React, TypeScript, and Tailwind CSS that connects to an HM-10 BLE module over the Web Bluetooth API.
- RubberOtter — Rubber Otter runs on an ATmega32U4-based microcontroller (Arduino Leonardo or Pro Micro are supported). The firmware listens on a serial Stream (by default Serial1 — hardware UART connected to an HM-10 BLE module). Each incoming framed packet is parsed by the Packet Parser module and passed to the Command Executor.
- ApexBridge — ApexBridge is a lightweight and efficient library designed for ESP8266 and ESP32 devices to seamlessly interact with Oracle APEX RESTful services. It simplifies sending authenticated HTTP requests and managing API endpoints securely.
- prompts-and-skills — A production-grade, structured repository dedicated to high-level AI System Prompts, Agentic Skills, Security Audit Frameworks, and Architectural Guidelines for modern Large Language Models (LLMs) and Autonomous AI Agents.
- resumesh-scrapers — resumesh-scrapers is a clean, modular, and robust Python library containing standalone scraping services for GitHub, Dev.to, Medium, Substack, Behance, NPM, and PyPI platforms.
- robo-market-search — Türkiye'nin en popüler 4 elektronik ve robotik pazarında (Robolink, Robotistan, Robo90, Direnç.net) tek satır kodla, çok hızlı ve eşzamanlı arama yapmanızı sağlayan Python istemci kütüphanesi.
- ResuMesh — ResuMesh is a self-hosted, dynamic portfolio hub designed for modern developers. Instead of maintaining static personal websites, ResuMesh continuously syncs your digital footprint from GitHub, Medium, and Dev.to into a single, unified database.
Let's build the future together.
