Analog and digital designer. Programmer of micro controllers in C or Assembly.
Schematic, and PCB design and manufacture.
35 years experience in the electronics industry, from R&D to industrial systems.
BSEE: Devry Institute of Technology 1979-1980 & 1987-1988.
I have been involved with electronic engineering, and systems repair for the last 35 years. I have designed everything from radios to computers, and everything in between.
My methods are simple. Design the needed system, do the coding, prototyping, and testing. if all tests pass.then create the schematic, design the PC board and Gerber files, and have some samples manufactured. Then in the lab solder all components on the board, whether through hole or surface mount types. Test the circuit board, and deliver the product with all details.

I design draw and engineer almost anything with precision and accuracy. As a multi-talented perfectionist, I've been staring at a display device for over 30 years. I have worked on thousands of projects, from intricate machine parts to complex systems. Design, draw and build projects include processing equipment, control enclosures, power and distribution, platforms, process piping, signs and displays, trailers, electronics and schematics. I have 13 years of hands on experience in the metal fabrication and machine shop environment. Using a Proactive process with a scheduled Implementation makes for a profitable product, reducing waste, rework or delays. In metal fabrication, it all begins with a design concept. Materials selection takes us to a cut list, shear, saw, punch, laser, form, weld, fasteners and finish. I work with AutoCAD, Solidworks, Coreldraw, and MS Office applications to create 2D and 3D documentation, adding assembly details and bills of materials. Many of my projects are confidential for the Nuclear Industry and other patented processes. My goal is your complete satisfaction.

I design embedded electronics that make it to manufacturing/production.
10+ years of experience routinely designing custom electronics, embedded firmware, and control systems. My work spans the whole product lifecycle—from early breadboard prototypes and proof-of-concepts to production-conscious hardware with designs for manufacturing and assembly. I enjoy solving engineering problems that don't have an off-the-shelf solution. My goal is to build something that's reliable and manufacturable for you, and to work on anything new and interesting for me.
Recent work includes designing embedded control systems for commercial beverage equipment. It features custom PCBs, STM32-based HMIs, refrigerated dairy management, peristaltic pump control, industrial sensors, and Raspberry Pi & Arduino-based prototypes. Before that I was working on ultrasonic algae killers, and before that consumer appliances.
Most of my experience deals with motor/sensor integration and hardware/firmware built around real world problems. How can we build a modular single-family EV charging station that can accept multiple possible power inputs? How does our UI drive user inputs? How can we control 14 types of sensor data in a way that drives our motors logically? From large-scale automated greenhouse systems to a fantastic automated beverage experience, it all boils down to hardware/software interactions.
Many of my clients return for multiple prototype revisions and long-term product development because I strive to be more than a contractor—I aim to be a reliable engineering partner throughout the life of a project. My longest running current contract is over 2 years old.
Good engineering is about more than making a prototype function. Every design decision should consider manufacturability, reliability, cost, long-term component availability, serviceability, and future scalability as early as possible. I enjoy collaborating with clients early and often in the design process to avoid expensive redesigns later.
Whether you're starting with a sketch on a napkin, a breadboard prototype, or an existing design that needs refinement, I'd be happy to help bring your product to life.

Hi, I am Md. Redwan Islam, a Computer Science graduate researcher at the University of Georgia with strong experience in machine learning, artificial intelligence, knowledge graphs, graph neural networks, LLM-based workflows, IoT systems, cloud-based analytics, and research-oriented software development.
My recent work focuses on applied AI/ML research and implementation, especially graph-based AI, dynamic graph neural networks, knowledge graph construction, biomedical knowledge representation, explainable AI, and LLM-assisted research systems. I have worked on projects involving biologically inspired framework for scalable and adaptive graph neural networks on various large datasets.
I also work on knowledge graph-based biomedical AI, including antimicrobial resistance, horizontal gene transfer, mobile genetic elements, and scientific data integration from heterogeneous biological databases. My experience includes building structured pipelines for data collection, entity-relation modeling, graph construction, semantic representation, graph analytics, and machine learning over complex scientific datasets.
In addition to graph AI and knowledge graphs, I have experience with LLM applications, retrieval-augmented generation concepts, AI research automation, question-answering systems, literature-based reasoning, prompt engineering, and integrating LLMs with structured data sources. I can help design AI workflows that connect plain-language questions to databases, knowledge graphs, APIs, or analytical pipelines.
At the University of Georgia, I have worked as a Graduate Research Assistant and Graduate Teaching Assistant, supporting courses such as Data Mining, Discrete Mathematics, and Data Science. My academic and research background includes machine learning, deep learning, data mining, signal processing, public health analytics, IoT-based real-time data collection, and cloud-based data analysis. I have also contributed to research involving NHANES data analysis, explainable public health analytics, Raman spectroscopy with machine learning, and brain-computer interface signal classification.
Before joining UGA, I completed my B.Sc. in Electrical and Electronic Engineering from Bangladesh University of Engineering and Technology. During my undergraduate research, I published an IEEE conference paper on electrocorticography-based motor imagery signal classification using continuous wavelet transform. I later worked as an IoT Software Developer at DataSoft Systems Bangladesh and as a Satellite Operation / Computer and Data Center Engineer at Spectra International Limited, where I contributed to the Bangabandhu Satellite-1 project with Thales Alenia Space, France. That work involved server installation, application software maintenance, networking equipment, switches, routers, and data center infrastructure.
I can help with:
Machine Learning and Deep Learning
Graph Neural Networks and Graph Analytics
Knowledge Graph Construction and KG-Based AI
LLM Applications and RAG-Style Workflows
Biomedical and Scientific AI Pipelines
Python Data Analysis and Research Prototyping
NLP, Data Mining, and Text Analytics
IoT Data Collection and Cloud-Based Analytics
Database Design, APIs, and Backend Development
Academic Research Coding, Experimentation, and Paper-Ready Results
My technical stack includes Python, PyTorch, TensorFlow, Keras, scikit-learn, NumPy, SciPy, Pandas, R, MATLAB, Java, C/C++, C#, JavaScript, Node.js, REST APIs, Django, Laravel, SQL, MySQL, MongoDB, Linux, Docker, Git, GitHub, AWS, Azure, SPSS, LaTeX, and data visualization tools.
I am especially interested in projects where AI research needs to be turned into a working prototype, reproducible codebase, analytical pipeline, technical report, or production-ready proof of concept. If your project involves machine learning, knowledge graphs, LLMs, graph data, scientific datasets, biomedical AI, or research-driven software development, I can help you build it carefully, clearly, and rigorously.
