Do manual data entries, disjointed business tools, and messy spreadsheets slow down your daily operations? I build custom, cross-platform mobile applications and advanced backend automation pipelines that handle your workflows hands-off. By combining the speed of low-code environments with the raw processing power of custom Python scripting, I help businesses transform chaotic datasets into highly structured, automated, and secure software solutions. 🛠️ CORE SPECIALTIES & STACK: • Custom Mobile & Web Apps: High-performance business tools built via AppSheet, integrated natively with Google Sheets or relational database layers. • Custom Python Tools & Desktop Apps: Standalone utility tools and user interfaces (GUI) engineered to execute complex file processing, automation logic, and local tasks. • Advanced Workflow Automation: Designing zero-maintenance backend cloud pipelines and webhook connections using Make and Zapier. • Advanced Data Engineering: Deep text parsing, pattern matching, and comprehensive data extraction pipelines utilizing complex Regular Expressions (Regex). ⚙️ MY PROCESS: 1. Discovery & Architecture: We map out your current data flow and design a stable database structure. 2. Custom Engineering: I build out your application layouts, write optimized code logic, and deploy cloud triggers. 3. Optimization & Compiling: I run performance tests to prevent execution timeouts and compile desktop tools into ready-to-run files. Stop wasting valuable hours fighting system limitations.

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.
