I develop, debug, and convert TradingView Pine Script and MT5/MQL5 tools with clean documentation, testing steps, and human-review checkpoints. I also build AI-assisted workflow automation using n8n, Claude, APIs, and Python, with a focus on logging, maintainability, and risk-aware design. My past work includes indicator debugging, strategy conversion, backtesting support, automation workflows, and EdTech tools backed by 30 years of teaching experience. AI Workflow Automation Your AI employee who never sleeps. I design business workflows using Claude MCP, Cowork, and n8n that automate repetitive tasks. Submit work at night, wake up to results. Quarterly maintenance subscriptions keep your setup current as AI tools evolve. Recent: AI workflow consultation for a beauty salon. Trading Tool Development From 1,850 live trades to your custom algorithm. Pine Script indicators for TradingView (QQE v3.0 with strong community support), MT5/MT4 Expert Advisors with verified backtest results, NinjaScript strategies, and TradeStation EasyLanguage. Cross-platform deployments where the same logic runs consistently on every platform. Educational Technology Claude Code + MCP + 30yr STEM Expert = Your unfair advantage. AI-powered question generators, exam preparation apps (530+ question database for university entrance exams), and STEM curriculum development. I combine deep subject matter expertise with AI to produce educational content that works. I work through text-based asynchronous communication. This produces clearer specifications, better documentation, and a complete record of every decision. Portfolio links: See my GitHub, MQL5, and YouTube profiles in the Portfolio section below.

I build full-stack automation systems, API integrations, serverless backends, data pipelines and AI-assisted business workflows. My work can cover the complete delivery path—from an operator dashboard and API layer to databases, queues, background workers, cloud infrastructure, testing and client-ready documentation. I use Python, TypeScript, Node.js, Next.js, FastAPI, AWS, PostgreSQL/Supabase, Docker, n8n and modern AI APIs to turn manual or fragile operations into structured, maintainable systems. What I build: ▸ Full-stack automation systems Internal dashboards, administrative tools, campaign interfaces and operational workflows using Next.js, TypeScript, Node.js, Python and PostgreSQL. I can deliver both the user-facing interface and the backend systems that power it, rather than leaving you to coordinate separate front-end and backend developers. ▸ AI-assisted workflows Controlled use of Claude and GPT for classification, extraction, summarisation, routing, draft generation, decision support and human-in-the-loop review. I treat an LLM as one component inside a reliable business process—not as a magic box expected to manage everything by itself. ▸ API and webhook integrations REST APIs, webhooks, authentication, retries, idempotency, structured logging, validation, error handling and data normalisation. Integrations can include Airtable, Google Workspace, Stripe, Shopify, Slack, Twilio, OpenAI, Anthropic Claude and custom platforms. ▸ AWS serverless and backend engineering AWS Lambda, API Gateway, Amazon SQS, DynamoDB, PostgreSQL, background workers, rate limiting, dead-letter queues, event processing and deployment infrastructure. I focus on systems that remain predictable under duplicate events, retries, partial failures and changing workloads. ▸ n8n and workflow automation Reusable n8n workflows with clear triggers, API nodes, Code nodes, validation, error routes, structured logs and maintainable handover documentation. I avoid fragile visual spaghetti and design workflows that another person can understand and operate. ▸ Python automation and data processing CSV, Excel and PDF workflows, scheduled jobs, reporting tools, data validation, back-office utilities and repeatable processing pipelines. ▸ Web scraping and structured data extraction Maintainable Python-based extraction systems for public websites, dynamic pages and messy real-world data sources. Deliverables can include deduplication, validation, retry handling, polite rate limits, structured CSV or Excel output and clear re-run instructions. Recent engineering work: • Designed and built a production-oriented Twilio Conference orchestration reference implementation using TypeScript, AWS Lambda, API Gateway, SQS, DynamoDB, PostgreSQL, Next.js, Docker and AWS CDK. • The independently audited release passed 573 tests and completed a deterministic simulation of 15,000 transfer pairs with zero pair-integrity violations. No real telephone calls were made; the simulation measured application-side orchestration. • Delivered a Python data-collection system that converted public directory information into verified, structured CSV and Excel outputs for an international client. • Created implementation-ready automation packages covering architecture, technical requirements, validation scripts, deployment guidance and client handover materials. Why work with me: ▸ End-to-end delivery I can handle the interface, backend, integrations, infrastructure, testing and documentation as one coherent system. ▸ Lightweight by default I build the smallest reliable solution that solves the actual problem. I will not introduce an oversized framework when a focused service or workflow is enough. ▸ Reliability-focused I design for duplicate events, retries, validation failures, partial outages and safe recovery—not merely the happy-path demonstration. ▸ Documentation-first I provide clear written updates, architecture notes, setup instructions, testing evidence, acceptance criteria and practical handover documentation. ▸ English and Japanese support I can work with English and Japanese requirements, websites, data and documentation. I work particularly well with asynchronous, written communication. Core stack: TypeScript, Node.js, Python, Next.js, FastAPI, PostgreSQL, Supabase, AWS Lambda, API Gateway, Amazon SQS, DynamoDB, Docker, n8n, Playwright, pandas, REST APIs, webhooks, Twilio API, OpenAI API and Anthropic Claude API. To get started, send me a short description of the process, system or integration you need. I will respond with a practical scope, architecture recommendation, assumptions and proposed delivery plan.

Hi, I’m Yoshiyuki - a full‑stack and front‑end web developer with 25+ years in IT and 13 years building modern web applications. I love creating clean, user‑friendly, and scalable software, and I enjoy working closely with clients to turn ideas into something real and useful. My main tools are Angular, Java, TypeScript, Node.js, AWS, and Google Cloud, and I’ve recently added AI‑accelerated development to my workflow. Using tools like Copilot and Claude helps me move faster, explore more ideas, and deliver MVPs and prototypes quickly - while still keeping the code clean and maintainable. What I can help you build - Fast MVPs and prototypes - Internal tools and dashboards - CRUD applications - Front‑end architecture (Angular specialist) - Cloud‑ready applications (AWS / GCP) - AI‑assisted development for rapid delivery A bit about my background I’ve led teams, built internal Angular libraries used across 10+ teams, redesigned front‑end architectures for long‑term sustainability, and delivered MVPs for government and enterprise clients. I’m comfortable taking a rough idea and turning it into a working product. How I work - Friendly and easy to communicate with - Clear explanations and regular updates - Clean, maintainable code - Fast iteration using AI‑assisted workflows - Flexible with time zones and schedules If you’re looking for someone who can move quickly, collaborate openly, and deliver solid, future‑ready software, I’d be happy to help bring your project to life.
