Robbinsville Township, United States - 1:15 pm local time
Need a senior software engineer who can take ownership of your project—not just complete isolated coding tasks?

I bring 24+ years of software engineering experience, including 16 years in senior engineering roles within the banking industry. I build production-ready software using C#/.NET, Python, AI, APIs, React, SQL Server, and modern cloud technologies.

I help businesses turn complex requirements, unfinished applications, integration problems, and product ideas into secure, reliable, and maintainable software.

I can help you with:

• Custom SaaS platforms, business applications, dashboards, and internal systems
• AI applications, RAG systems, chatbots, document intelligence, and workflow automation
• Python automation, data processing, backend services, and AI integrations
• REST APIs, WebSockets, webhooks, payment integrations, and data pipelines
• C#/.NET and Python application development, modernization, troubleshooting, and performance optimization
• React web applications and administrative dashboards
• Desktop applications, Windows services, SQL Server, and database-intensive systems
• Algorithmic trading systems, broker integrations, backtesting platforms, and automated execution

I am particularly effective when:

• Requirements are complex, incomplete, or need technical clarification
• An existing developer left behind unfinished or unstable code
• AI-generated code needs professional review and production hardening
• Multiple APIs, platforms, databases, or external services must work together
• A prototype needs to become a secure, scalable, and maintainable product
• A trading system requires accurate execution, risk controls, logging, and testing

My technical stack includes C#, .NET, Python, FastAPI, Flask, React, JavaScript, SQL Server, PostgreSQL, REST APIs, WebSockets, automation, system integration, and cloud deployment.

For trading technology, I work with NinjaTrader 8, Interactive Brokers API, TradingView, Pine Script, options-trading systems, Telegram and Discord integrations, automated execution, backtesting, and risk-management software.

I personally handle requirements analysis, architecture, technical decisions, client communication, development oversight, and delivery. For larger projects, additional frontend, mobile, QA, UI/UX, or DevOps resources can be provided transparently through my Upwork agency.

Send me your requirements, existing source code, screenshots, or API documentation. I will help identify the appropriate architecture, technical risks, delivery milestones, and practical path to completion.
