I build custom web applications using TypeScript, React, Next.js, PostgreSQL and modern backend tools — from database design and authentication through APIs, business logic, testing and deployment.

Best for: SaaS products, internal tools, dashboards, customer portals and business applications.

I build AI-powered workflows that turn messy business information into structured, actionable processes. AI handles the interpretation, while deterministic validation and human approval keep important decisions under control.

Best for: document processing, request intake, operational workflows and repetitive business processes.

I build structured AI workflows with model integrations, validation, human-in-the-loop approval, safety controls, audit trails and controlled actions.

Best for: AI assistants, agentic workflows, document processing and AI-powered business tools.

I connect business systems through n8n, webhooks, APIs and custom application logic to automate information flow between tools.

Best for: intake automation, AI pipelines, notifications, data synchronization and custom business workflows.

I build systems that turn PDFs, receipts, forms and unstructured business requests into structured, validated data.

Best for: invoices, receipts, customer requests, operational documents and AI-assisted data entry.

I build responsive dashboards and internal applications that turn business data into useful workflows, reports and decision-making tools.

Best for: operations dashboards, financial tools, admin panels, review queues and internal business software.

I review existing web and AI applications for common security and reliability weaknesses and implement practical fixes.

Areas include authentication, authorization, input validation, webhook security, rate limiting, AI safety, duplicate requests, audit logging and failure recovery.

I add automated testing and reliability checks to full-stack applications, including unit tests, integration tests, API/security regression tests, database testing and CI verification.

Best for: applications that work but need confidence before release or further development.
