Project details
Most backend MVPs are built to demo, not to scale. When real users hit them - payment flows break, auth leaks under edge cases, and the architecture that seemed fine at 100 users collapses at 10,000. I build the backend layer that holds.
With 7+ years shipping production systems for fintech companies, Web3 platforms, and enterprise SaaS clients - including XBTO ($217M institutional platform), Bitclear (global crypto payment processor), and Garantme (Series B, €15M) - I know where backend systems fail before they fail.
What you get is a production-ready backend: clean architecture, proper auth and RBAC, tested API endpoints, third-party integrations that don't drift, and deployment that doesn't require a DevOps team to maintain. No shortcuts, no technical debt handed off as a deliverable.

STL Buddy Website Development
Victoria did a great job as a full-stack developer on our 3D model marketplace. She handled React, Node.js, API integrations, search/previews, and marketplace workflows with clear communication and reliable delivery. I'd happily recommend Victoria and Vicode Solutions for full-stack web development.

Full-Stack Developer (React + Node.js) to Help Complete Ongoing Product
Victoria is a great and reliable full-stack developer. She helped me with several tasks in our SaaS project.
She worked with React and Node.js, communicated clearly, and delivered everything on time. The code was clean, and the features worked as expected.
Great experience overall, would recommend!

Dubai, United Arab Emirates - 7:51 pm local time
I'm Victoria, a senior full-stack engineer with 7+ years shipping production systems across SaaS platforms, fintech products, and AI-powered applications. React, Next.js, Node.js, NestJS, PostgreSQL, AWS. I focus on full-stack architecture, APIs, and AI integrations - from LLM-powered features to document automation to systems serving tens of thousands of users.
𝗪𝗛𝗔𝗧 𝗜'𝗩𝗘 𝗕𝗨𝗜𝗟𝗧
Deverus - serves 35,000+ businesses and processes 2.5 million hires per year. I worked on a legacy SaaS portal redesign and integrated an AI chatbot with ML document parsing to automate the applicant flow.
EndoDNA - a personalized health platform delivering DNA-based wellness insights. I built AI-assisted recommendation logic, healthcare analytics, and secure patient-facing dashboards on React and Node.js.
Fortune - a fintech SaaS for cashflow forecasting and financial analytics across multiple banks. I worked on backend architecture, financial data integrations, predictive analytics, and dashboard performance where data accuracy and system reliability are non-negotiable.
XBTO - an institutional digital asset platform with $217M in capital commitments. I built backend services, secure financial APIs, and scalable infrastructure supporting real-time trading and risk management for professional investors in a regulated environment.
Garantme - a French PropTech SaaS, Series B funded at €15M, with around 100 employees. I built product features inside a live microservices architecture - Node.js, GraphQL, MongoDB - working alongside their team without disrupting a platform already serving thousands of real estate professionals.
𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 𝗙𝗢𝗥 𝗬𝗢𝗨
Full-stack applications - React, Next.js, Node.js, NestJS, TypeScript, REST APIs, authentication, RBAC, background jobs, queues, caching, and systems that hold up under real load and real users.
AI integrations - Claude and OpenAI API integration, LangChain and LangGraph agent workflows, RAG pipelines, document automation, and AI features built with the same rigor as the rest of the product, not bolted on.
Fintech and payment systems - payment gateways, financial dashboards, subscription billing, and third-party financial integrations built around edge cases, not despite them.
SaaS platforms - user management, subscriptions, admin portals, reporting, and enterprise workflows built to scale without accumulating technical debt.
