I have implemented Systems for Military Fiber Glass submarine, Rovers in active combat (please check portfolio) , Custom Drone Frames with Anti-Jamming & RF Communication (demo available on request) Aircraft Communication Equipment for Mountain RF. Look into my portfolio for images and videos. In my 27 years of career I have solved complex bottlenecks and implemented scalable systems on software and electronics both. Specific Hardware & Silicon Expertise: FPGA & RF: Xilinx Zynq-7020, PYNQ, Digital Down Conversion (DDC) IP Cores, NCO/PLL architecture, HackRF, Autonomous SDR systems. Embedded SoCs: STM32 (H7/F4), ESP32-S3, ARM Cortex-M. Physical Layer: Altium Designer, High-Speed Signal Integrity, Thermal Analysis, DFM/DFA/EMC compliance for Defense and Medical hardware. Protocols & Architectures: * ACARS/ED137 ground station radio standards. * Zephyr RTOS & FreeRTOS deterministic task scheduling. * NIST Post-Quantum Cryptography for edge devices. * Edge AI (TinyML) inference pipelines under thermal constraints. **How I Work (The Guarantee):** When I deliver a Zynq IP core or an ESP32 firmware build, it comes with the "Ground Truth"—benchmark tables (latency, jitter, power draw) and physical oscilloscope verification. You are paying for risk reduction and guaranteed integration, not just lines of code. less -

My...AI, Data & Full-Stack Systems Architect with 6+ years of experience delivering 15+ production projects across six countries. I design, build, test and deploy complete software platforms—from data architecture and backend APIs to AI integration, user interfaces, cloud deployment and automated quality assurance. My strongest technologies are Python, Django and PostgreSQL, supported by extensive JavaScript/TypeScript experience with MERN and MEAN applications. As an EU citizen, I offer convenient working-hour overlap for European and US clients. ## What I Build • AI & Generative AI: LLM applications, RAG systems, AI agents, chatbots, semantic search, structured outputs, function/tool calling, prompt engineering, model integration and evaluation. • Data Engineering: ETL/ELT pipelines, data ingestion, transformation and validation, database design, query optimization, time-series processing, IoT sensor integration and data-quality automation. • Full-Stack Systems: scalable APIs, responsive web applications, authentication, third-party integrations, background processing and real-time communication using WebSockets and SSE. • DevOps & Cloud: containerized deployment, Linux environments, CI/CD workflows, asynchronous services, production configuration and deployment automation. • QA Automation: API, integration, regression and end-to-end testing, validation scripts, test-data workflows and automated quality gates. ## Technical Stack AI: OpenAI API, Anthropic, Gemini, Hugging Face, LangChain, LlamaIndex, PyTorch, TensorFlow and scikit-learn. Vector infrastructure: FAISS, Chroma, Pinecone and pgvector. Backend & frontend: Python, Django, Django REST Framework, Falcon, Node.js, Express, React, Angular, JavaScript, TypeScript, C#/.NET and Java.
