Hire the Best Web Services Specialists
in the United States

Full-stack developer based in San Francisco (PST). I take founders from idea to a live, production app, fast, and with senior-level execution. In the past year I've shipped 5 products end-to-end: • ChekBack - a receipt-cashback app • PhotoOffice - an AI passport-photo service • ChessTourism - a chess-tournament platform • Pluto - a field-service management system for home-service companies • MotoSocial - a social network for motorcyclists Each one went from concept to deployment, including auth, payments, integrations, and infrastructure. Why clients work with me: • US-based, real-time overlap with your business hours • Native, clear English on calls and in writing • Senior delivery - I ship working software, not just plans • I stay with you until your app is published - I never leave you alone with your issues or concerns • Warranty after delivery - if something breaks on my work, I fix it, no extra charge Core stack: React, React Native, Next.js, TypeScript, Node.js, PostgreSQL. Also: Python (FastAPI/Django), Expo, Redis, AWS/Hetzner/Cloudflare, CI/CD, REST & GraphQL, CRM and third-party integrations. Best fit for: founders and startups who need an MVP or full product built right, the first time. Send me your idea and I'll reply with a rough scope and timeline. No charge.

I build production-grade systems that handle real-world complexity - not prototypes that break under actual usage. I didn't start as a developer. I came up through IT operations at a healthcare organization, dealing with broken EHR integrations, sync failures, and workflows that crashed when clinicians needed them most. For several years, I was the person called when systems went down. That's when I started writing code - starting with scripts to automate my own troubleshooting, then building tools to fix recurring problems. Scripts became utilities. Utilities became systems. Eventually, I wasn't just keeping software running - I was building it. Over the last 10 years, I've worked on SaaS platforms, healthcare applications, e-commerce systems, and AI-powered automation. I've designed multi-tenant architectures serving thousands of users, built APIs processing millions of requests, and integrated AI into workflows that reduced manual operations by 70%+. My operations background gave me something most developers lack: understanding how business logic actually functions in production. I don't just ship features - I understand the workflows they enable, the edge cases that break them, and the business rules that define them. I focus on outcomes, not just technical implementation. What I Do - SaaS platforms: Multi-tenant architecture, subscription billing, role-based permissions, complex business rules, real-time sync, API integrations. - AI & automation: LLM integrations (GPT, Claude), RAG pipelines, document processing, workflow automation, AI agents handling real business logic. - Healthcare systems: EHR integrations (HL7, FHIR), HIPAA-compliant architecture, clinical workflows, patient data sync, billing logic, audit logging. - Business logic: Complex validation rules, multi-step workflows, conditional processing, data transformation pipelines, integration orchestration. I've built systems handling 10k+ documents monthly, processing thousands of daily transactions, and syncing data across dozens of third-party platforms without failure. Tech Stack - Backend: Node.js, Python, TypeScript, Express, NestJS, FastAPI, Django - Frontend: React, Next.js, Vue.js, TypeScript, Tailwind CSS - Database: PostgreSQL, MongoDB, Redis - Cloud: AWS (EC2, ECS, S3, Lambda, RDS), Azure, Docker - AI: OpenAI API, Claude API, LangChain, RAG - Healthcare: HL7 v2, FHIR R4, HIPAA compliance - APIs & Integration: REST, GraphQL, WebSockets, OAuth 2.0, Stripe - Infrastructure: CI/CD, RabbitMQ How I Work I communicate clearly and directly. I ask the right questions upfront to understand business logic and constraints. I document what I build. I test comprehensively before deployment. I think about failure scenarios and real-world usage - not just ideal conditions. I work remotely, manage my own timelines, and operate independently. I'm not the cheapest option. But I deliver clean, scalable systems that work in production, handle complex business logic correctly, and remain stable long-term.

I'll tell you in the first conversation whether what you're planning will actually work in production.

Whether you're exploring AI for the first time or trying to improve an existing system, the biggest challenge isn't building AI, it's building AI that actually works for your business. And worse still, many AI projects never deliver the value they promised because they're built around the technology instead of the people and processes they're supposed to improve. The result? → AI agents that break the moment real users go off-script. → RAG systems that hallucinate instead of retrieving the right information. → Automations that create more work instead of saving time. → Teams that stop using AI because they don't trust it. That's where I come in. The best AI implementations don't start with models or frameworks. They start by understanding how your business operates, identifying where people spend time making repetitive decisions, and then building AI around those workflows I help businesses build AI systems people actually rely on, whether it's AI agents, RAG pipelines, or an LLM-powered automation system that run in production. Startups and growing businesses hire me when they need intelligent AI systems that actually work: agents that execute multi-step tasks, RAG systems that surface accurate answers from their data, and automation workflows that eliminate hours of manual work daily. I work with startups, agencies, and service businesses that want to automate operations, improve customer experience, and unlock the value of their business data with AI. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⭐ CLIENT RESULTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ "Victor delivered a multi-agent RAG system in 3 weeks that cut our support ticket volume by 60%.
