You will get A Node.js API integration for your SaaS product
Project details
You will get a Node.js / TypeScript backend API integration for your SaaS product.
I can help build or fix integrations with third-party APIs, internal services, webhooks, data sync flows, background jobs, and backend automation. My focus is not only making the API call work, but making the integration reliable: validation, error handling, retries, logging, clear data flow, and production-ready behavior.
This is a good fit if your SaaS product needs to connect with an external platform, payment provider, CRM, marketing tool, analytics system, cloud service, or internal API.
My background is 10+ years in backend engineering with Node.js, TypeScript, APIs, SaaS platforms, cloud infrastructure, queues, Redis, PostgreSQL, AWS, Azure, CI/CD, and production support.

About Vitaliy
Senior SaaS Backend & AI Architect | Node.js, TypeScript, GenAI
Ternopil, Ukraine - 9:42 am local time
My strongest area is backend engineering for products that are more complex than a simple CRUD app: API integrations, data flows, distributed services, background jobs, event-driven systems, monitoring, and deployment pipelines.
I can help before implementation as well: technical discovery, architecture review, AI workflow assessment, delivery gap analysis, implementation planning, and roadmap definition. If implementation is needed, I can personally own the senior backend/AI work and coordinate trusted specialists for Go, DevOps, frontend, or QA when appropriate.
What I can help with:
- Node.js / TypeScript backend architecture
- SaaS backend modernization
- API gateways and third-party integrations
- PostgreSQL, Redis, MongoDB, Snowflake, and DynamoDB-backed systems
- AWS/Azure infrastructure, Docker, Kubernetes, Terraform, and CI/CD
- Event-driven systems with Kafka, RabbitMQ, and NATS
- WebSocket and real-time backend systems
- GenAI/RAG workflows and AI automation for internal tools
- Backend performance, reliability, logging, and monitoring
Relevant experience:
- 2Solar: backend architecture, AWS services, AI/ML workflows, Google Maps/spatial processing, and SaaS platform engineering
- wewatch.gg: real-time esports analytics, Steam API integrations, caching, SEO rendering, and high-load backend work
- WoWyrd: patent-pending R&D/founder project focused on low-latency traffic analysis and backend security infrastructure
I’m a good fit if you need a senior backend engineer who can understand business logic, clean up technical complexity, design a practical delivery plan, and implement production-ready backend systems.
I can help with architecture reviews, backend audits, integrations, MVP backend delivery, modernization, performance fixes, and long-term SaaS platform development.
