Project details

I will build or modernize a complete web application—from responsive UI and user flows to APIs, databases, authentication, integrations, testing, deployment, and handoff.

This service suits SaaS products, portals, dashboards, internal tools, business systems, and existing applications that need reliable new features.

Depending on scope, delivery can include frontend components; backend APIs and database design; authentication and authorization; payment, email, AI, or third-party integrations; automated tests; Docker deployment; logging, health checks, backup guidance, and technical documentation.

Relevant work: FinBot (architecture, APIs, data pipelines, authentication, notifications, and production operations), CANSLIM (real-time data workflows, scheduled jobs, web interfaces, and deployment), and Vhat Monitor (monitoring dashboards, health checks, logs, and incident investigation).

Send me your goal, users, current system, designs, and constraints. I will help define a practical first milestone. For larger scopes, I can coordinate a 10–15 person engineering team after transparent agreement on roles, cost, and delivery.

Software Solutions Engineer | Full-Stack, AI, Cloud & Automation

Have a software problem that needs a practical, maintainable solution? I can take ownership from analysis and architecture through implementation, integration, deployment, troubleshooting, and operations.

I help businesses with:
• Full-stack web applications, internal tools, SaaS, and business systems
• Backend APIs, databases, authentication, and third-party integrations
• AI agents, workflow automation, chatbots, and repetitive-process reduction
• Data crawling, ETL pipelines, scheduled processing, and reporting
• Cloud servers, Docker, CI/CD, monitoring, performance, and incident response
• Security hardening, infrastructure monitoring, and intrusion detection
• Legacy-system debugging, modernization, migration, and difficult production issues

I work across .NET/C#, Node.js/TypeScript, Python, modern web technologies, SQL/NoSQL databases, Linux, and cloud infrastructure. I also bring strong domain understanding in education technology, finance, and business operations.

You do not need to arrive with a perfect specification. Share the problem, current system, constraints, and desired outcome. I will help clarify the scope and propose a practical first step.
