Project details
You will get a high-quality full-stack web application designed to perform, scale, and deliver real business value. As a Senior Full Stack Developer, I specialize in React, Angular, and Node.js to build secure, responsive, and user-focused solutions.
Whether you need a SaaS MVP, business dashboard, AI-powered tool, or enterprise platform, I deliver systems built with clean architecture, optimized performance, and reliable backend infrastructure. I handle frontend, backend, APIs, authentication, databases, and deployment from end to end.
You will receive a modern, professional product that works across devices and browsers, integrates with third-party services, and is easy to maintain. My process includes clear communication, transparent delivery milestones, and documented source code so you can continue development confidently.
I care deeply about delivering solutions that scale not just code that works. My goal is to help your business launch faster, operate smoother, and grow with confidence.

I help startups and growing businesses build 𝘀𝗰𝗮𝗹𝗮𝗯𝗹𝗲 𝗦𝗮𝗮𝗦 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝘀 with production 𝗔𝗜. From 𝗔𝗜 𝗮𝗴𝗲𝗻𝘁𝘀 and 𝗥𝗔𝗚 𝗽𝗶𝗽𝗲𝗹𝗶𝗻𝗲𝘀 to APIs and automation, I deliver 𝗳𝘂𝗹𝗹-𝘀𝘁𝗮𝗰𝗸 + 𝗔𝗜 𝗶𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻.
With 17 years of engineering experience, I can own the full system from architecture and database design through development, security, testing, deployment, and production support.
𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗦𝗮𝗮𝗦 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁
I build secure, maintainable applications using proven technologies:
𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱: Next.js, React, TypeScript, JavaScript, Tailwind CSS
𝗕𝗮𝗰𝗸𝗲𝗻𝗱: Python, FastAPI, Node.js, Express
𝗗𝗮𝘁𝗮𝗯𝗮𝘀𝗲𝘀: PostgreSQL, Supabase, Cosmos DB, Redis
𝗖𝗹𝗼𝘂𝗱: AWS, Azure, GCP, Vercel, Docker
𝗗𝗲𝘃𝗢𝗽𝘀: Terraform, GitHub Actions, CI/CD, monitoring and logging
I specialize in 𝗺𝘂𝗹𝘁𝗶-𝘁𝗲𝗻𝗮𝗻𝘁 𝗦𝗮𝗮𝗦, authentication, SSO, roles and permissions, tenant isolation, admin dashboards, billing workflows, internal tools, APIs, webhooks, and background processing.
𝗔𝗜 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 & 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻
I add practical AI features to new and existing products:
▪ 𝗔𝗜 𝗮𝗴𝗲𝗻𝘁𝘀 with tools, guardrails, and human review
▪ 𝗥𝗔𝗚 𝗽𝗶𝗽𝗲𝗹𝗶𝗻𝗲𝘀 with retrieval, reranking, citations, and evaluation
▪ Document extraction, classification, and workflow automation
▪ AI chat and voice assistants
▪ OpenAI, Anthropic, LangChain, and vector database integrations
▪ Knowledge bases that can be updated without redeploying the application
▪ LLM cost, speed, reliability, and quality improvements
▪ Prompt engineering, testing, monitoring, and safety controls
Many teams contact me after building an 𝗔𝗜 𝗽𝗿𝗼𝘁𝗼𝘁𝘆𝗽𝗲 that worked in a demo but was not ready for real users. I turn it into a secure, testable system their engineers can operate and improve.
𝗔𝗣𝗜𝘀 & 𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀
I build integrations with Microsoft Graph, Jira, Stripe, Twilio, Vapi, healthcare platforms, financial systems, and other third-party APIs.
My integration work includes OAuth, token refresh, tenant-specific credentials, webhooks, data synchronization, background jobs, retries, logging, and secure secrets management.
𝗛𝗲𝗮𝗹𝘁𝗵𝗰𝗮𝗿𝗲 & 𝗙𝗶𝗻𝗧𝗲𝗰𝗵 𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲
I have worked on five healthcare platforms, including EMR and RCM systems, patient portals, billing, and clinical workflow systems.
For one EMR/EHR module, I helped 𝗿𝗲𝗱𝘂𝗰𝗲 𝗽𝗵𝘆𝘀𝗶𝗰𝗶𝗮𝗻 𝗱𝗮𝘁𝗮-𝗲𝗻𝘁𝗿𝘆 𝘁𝗶𝗺𝗲 𝗯𝘆 𝟲𝟬% using document extraction, structured intake, previous-record data, and voice-assisted note drafting.
My FinTech work includes bill pay, banking, payment workflows, reconciliation, multi-tenant SaaS, audit logs, and secure handling of sensitive data.
