You will get Build a Scalable Enterprise Backend Architecture with NestJS and AWS
Rising Talent
Project details
Build a resilient, high-performance backend architecture designed for "Google-level" standards and long-term business growth.
As a Senior Full-Stack Architect, I specialize in engineering robust backend ecosystems using NestJS, PostgreSQL, and AWS. I don't just write APIs; I build scalable business assets that ensure data integrity, high availability, and security from the first line of code.
Why this architecture?
• NestJS Mastery: Modular, type-safe backend architecture that remains maintainable as your system grows.
• AWS Infrastructure: Expert setup of RDS (PostgreSQL), S3, SES, and EC2/Lambda for maximum performance.
• Database Integrity: Deep PostgreSQL design with optimized indexing, Row-Level Security (RLS), and strict transaction handling.
• Security First: Implementation of enterprise-grade API protection and secure Auth flows (RBAC).
My "Orchestrator" Process:
I leverage modern AI tools (Claude, Cursor) to accelerate development velocity while personally ensuring the architectural cohesion, security, and production-ready code quality that AI often misses.

Custom Web App with Dashboard, Tasks & Document AI
Vasyl is a skilled and creative developer who goes beyond just writing code — he actively proposes solutions and thinks through the architecture. What started as an MVP turned into a serious compliance platform with AI assistant, hierarchical access control, and automated task management. He handled a complex, evolving scope professionally and delivered a solid foundation for scaling. Recommended for serious projects.

Whether you're launching a SaaS MVP, integrating AI into an existing product, or untangling a legacy codebase — I treat your project like it's my own. You get senior-level engineering without agency overhead, and direct communication at every step.
🛠️ Core Stack:
Frontend: Next.js, React, TypeScript, Tailwind CSS, Framer Motion
Backend: Node.js, NestJS, REST & GraphQL APIs
Databases: PostgreSQL, Supabase, Firebase — with proper schema design, RLS, and indexing
AI & Integrations: OpenAI, Claude, Stripe, third-party APIs, webhook systems
Cloud & DevOps: AWS, Docker, Vercel, CI/CD pipelines
🎯 What I Build:
SaaS MVPs — from Figma or idea to production, fast
AI-powered web apps — intelligent features, document AI, LLM integrations
Internal tools & admin dashboards — complex data, clean UI
Custom APIs & integrations — Stripe, OAuth, third-party SaaS
Database architecture — secure schemas, multi-tenant RLS, optimized queries
Codebase refactoring — turning slow, legacy apps into fast, maintainable systems
🛡️ How I Work:
Security-first — auth and RLS from day one, never bolted on later
Async-first — clear written updates, no unnecessary meetings
You work directly with me — no middlemen, no surprises
My work and case studies: sanotskyi.dev
