I'm an experienced full-stack developer specializing in dynamic, scalable applications for small and medium-sized businesses. Whether you're looking to win new clients, showcase your services, or build a powerful business solution from the ground up, I've got you covered. My core foundation is in .NET C#, Blazor, and .NET MAUI, which I use to build modern web apps and cross-platform mobile and desktop applications. On the JavaScript side, I deliver fast, scalable solutions with React, Next.js, Node.js, and Express, and I'm equally comfortable crafting responsive, feature-rich websites with HTML, CSS3, Bootstrap, jQuery and PHP.

I build systems where hardware meets AI — ESP32 and Raspberry Pi firmware talking to computer vision pipelines, LangGraph agentic workflows, and cloud backends that scale. Six years of cross-domain engineering across embedded systems, machine learning, OCR, IoT platforms, and backend development. On the embedded and IoT side: production firmware for ESP32, STM32, and Raspberry Pi; ThingsBoard platform architecture and custom rule chains; AWS IoT Core, MQTT, and MODBUS integration; real-time industrial automation and remote monitoring systems. On the AI and machine learning side: trained and fine-tuned YOLO-based computer vision models on real production data; fine-tuned local LLMs including LLaMA and Mistral for domain-specific deployment; built OCR pipelines using EasyOCR and OpenCV for document intelligence and field data extraction; developed LangChain and LangGraph agentic AI systems; integrated OpenAI, Gemini, and DeepSeek APIs into production backends serving thousands of users. On the backend and SaaS side: FastAPI and Flask API development; PostgreSQL and Supabase database design; Redis and Kafka data pipelines; AWS Lambda, SageMaker, EC2, and S3; Stripe payment integration; real-time WebSocket systems; full SaaS product architecture from MVP to production. What I typically build: — Computer vision inspection and OCR systems trained on real field imagery, deployed to edge devices or cloud APIs with full preprocessing and postprocessing pipelines. — Multi-device IoT monitoring platforms with ThingsBoard, AWS IoT Core, real-time rule chains, relational backends, and custom dashboards — architected for scale from day one. — Document intelligence systems — automated extraction, classification, and processing of invoices, utility bills, forms, contracts, and scanned documents using OCR, YOLO, and LLM-based parsing pipelines. — Agentic AI systems using LangGraph and LangChain — RAG pipelines, multi-agent workflows, document Q&A systems, and LLM-powered automation built for production, not just demos. — Fine-tuned local LLMs and computer vision models — domain-specific training and deployment of LLaMA, Mistral, and YOLO variants on custom datasets for edge and cloud environments. — AWS IoT systems — end-to-end architecture using IoT Core, Lambda, DynamoDB, S3, SageMaker, and Greengrass for connected device fleets, telemetry pipelines, and cloud-to-device control systems. — SaaS products and MVPs — full-stack builds using FastAPI or Flask backends, Supabase or PostgreSQL databases, Stripe billing, and React or Next.js frontends; from zero to deployed and paying customers. — Industrial automation and embedded systems integrating sensors, actuators, communication protocols, and cloud connectivity across ESP32, Raspberry Pi, and STM32 platforms. — End-to-end backend infrastructure for data-heavy applications — API design, database architecture, real-time pipelines, and cloud deployment on AWS. I scope projects carefully, communicate proactively, and flag technical risks before they cost you time. If you're building something at the intersection of hardware and AI and need end-to-end ownership, let's talk.

Focused entirely on designing crypto and equities trading algorithms — building signal generation models in Python, backtesting against historical tick data, and training on Nvidia hardware for low-latency inference. I was trained classically, writing C and C++ code for Wall Street trading powerhouses like Goldman Sachs and Lehman Brothers. Running on advanced Unix systems, these lightning fast applications pioneered the field of today's realtime global FinTech. That low-level performance discipline is exactly what I bring to Python today: when a pandas pipeline or a pricing model needs to run faster, I know how to profile it, rewrite the hot path in C/C++, and bind it back in — rather than just accepting whatever speed the interpreter gives me. As the Internet spawned open source platforms like Linux, MySQL, NodeJS, and AWS Cloud API's, my skillset evolved into a full-stack portfolio: Python and C++ on the backend for quant logic and performance-critical services, NodeJS gluing together APIs and real-time data feeds, and JavaScript up front to deliver large, complex datasets through clean, intuitive web portals. That range — comfortable in Python's data/ML ecosystem, NodeJS's async API layer, and raw C/C++ when milliseconds matter — is what lets me own a fintech product end to end instead of handing it off between specialists. After moving to the West Coast in 2016, and spending time in Silicon Valley, I ventured into Blockchain protocol coding, video streaming/FFmpeg, and network traffic optimization down to the TCP/IP stack — all of it reinforcing the same core skill: designing and coding custom algorithms. Whether it's a Python model scoring trading signals in real time, a Node service exposing that model over a REST API, or a C++ routine doing the number-crunching underneath, the ability to move fluidly across that stack is what separates a production-ready fintech system from one that never leaves the GitHub repo. From my early career, I have made database structure the centerpiece of my application design. Classical training in Dr. E. F. Codd's model of Relational Databases has always informed my philosophy of how to structure an application's data repository. With web-scale data, this field has grown to NoSQL and Graph databases, and now huge datasets underpin the training of AI/ML models.
