You will get I will integrate AI features into your web app or SaaS product
Project details
I build practical AI features for existing products: chat, content generation, copilots, and workflow automation. I focus on stable integration into your current backend/frontend, with prompt design, safety checks, rate-limit handling, logging, and fallback behavior. You get clean production code, clear documentation, and predictable delivery milestones. This is ideal for SaaS teams that want to launch AI value quickly without compromising reliability or maintainability.

Frequently asked questions
About Sergey
Senior Full-Stack Engineer | React/Node.js | Python | SaaS & APIs
Baia Mare, Romania - 4:19 pm local time
I help teams deliver production-ready features quickly and safely, from bug triage to full feature delivery.
What I can do for you:
- React/Next.js frontends (TypeScript)
- Node.js, FastAPI, Django backends
- REST/GraphQL API design and third-party integrations
- PostgreSQL schema design and performance optimization
- CI/CD, Docker, and cloud deployments (AWS/GCP)
How I work:
1) Define scope and success criteria upfront
2) Ship in small, testable milestones
3) Provide clear progress updates
4) Deliver clean, maintainable code with documentation
Typical turnaround:
- Critical bug fixes: same day
- Small to medium features: 1-3 days
- Larger scopes: iterative milestones with clear estimates
If you need a senior engineer who can own tasks end-to-end and move fast without sacrificing quality, send me your requirements and I will propose a concrete implementation plan.
Steps for completing your project
After purchasing the project, send requirements so Sergey can start the project.
Delivery time starts when Sergey receives requirements from you.
Sergey works on your project following the steps below.
Revisions may occur after the delivery date.
Design integration architecture
I map prompts, API flow, guardrails, and fallback logic, then share an implementation plan before coding.
