I help businesses and startups build scalable applications, SaaS platforms and AI based systems that are ready for real users and long term growth.

What I can build for you:
-- SaaS platforms (multi-tenant systems, subscription models)
-- Full stack web applications (frontend + backend)
-- AI based features and automation workflows
-- Dashboards, admin panels, and internal tools
-- API integrations and backend systems
-- Real-time applications and scalable architectures

How we’ll work:
-- Understand your idea or current system
-- Define the best technical approach
-- Build step by step with clear direction

Send me a message with your requirements I’ll help you figure out the best way to build your project before you commit.
Programming Languages

Ionic + Angular Developer for RevenueCat & Stripe Integration We had a great experience working with Rovshen. He successfully implemented the payment system in our app with excellent attention to detail and clear communication throughout the process. He was professional, reliable, and delivered the work on time. We’re very satisfied with the results and would gladly work with him again on future projects. Highly recommended!

If you're building an AI powered product and need someone who can own the full stack
from LLM architecture to production UI you're in the right place.

I'm a Senior AI Full Stack Engineer with 8+ years of experience designing and shipping
systems that combine deep AI backends with polished, performant frontends.

My stack: Python (FastAPI, Django) · Node.js · Next.js · TypeScript · React ·
LangChain · LangGraph · OpenAI · Claude · Pinecone · PostgreSQL · AWS

─────────────────────────────────────────
WHAT I BUILD
─────────────────────────────────────────

→ AI Full Stack Applications
Next.js + Python backends with real-time LLM streaming, auth, and multi-tenancy

→ RAG & Knowledge Systems
Hybrid retrieval (dense + sparse), reranking, embedding optimization, citations

→ Agentic AI Systems
Tool-calling agents with memory, orchestration layers, and reflection loops

→ Scalable API Backends
FastAPI / Node.js microservices, async pipelines, RBAC, REST & GraphQL

→ Compliant Enterprise AI
HIPAA-ready healthcare AI, FinTech-grade secure backends

─────────────────────────────────────────
PRODUCTION SYSTEMS I'VE SHIPPED
─────────────────────────────────────────

✔ AI clinical documentation agent — HIPAA-compliant, EHR-integrated, in active use
✔ Enterprise RAG platform — hybrid search over structured + unstructured data at scale
✔ AI SEO intelligence SaaS — semantic analysis across billions of documents
✔ Geospatial risk engine — PostGIS + H3 + real-time scoring for PropTech client
✔ Autonomous ingestion agents — schema drift detection, background orchestration
✔ AI marketing SaaS — website and campaign generation from natural language prompts
✔ Secure multi-tenant SaaS — role-based access, audit logging, enterprise deployment

─────────────────────────────────────────
FULL STACK AI — WHAT THAT MEANS
─────────────────────────────────────────

Most AI engineers can't build the frontend.
Most frontend engineers can't architect the AI layer.

I do both — and I connect them cleanly:

- Python AI backend → FastAPI / LangGraph / async inference pipelines
- Node.js middleware → BFF layers, webhooks, queue workers, integrations
- Next.js frontend → Server components, streaming UI, real-time AI interfaces
- Vector + Relational DB → Pinecone, PostgreSQL, Redis, Elasticsearch
- Cloud → AWS (EC2, Lambda, S3, RDS), Docker, Kubernetes, CI/CD

─────────────────────────────────────────
HOW I WORK
─────────────────────────────────────────

I don't prototype and disappear. I take projects through:

Architecture → MVP → Production Hardening → Monitoring → Scale

You get: clean documentation, maintainable code, and a partner who communicates clearly
and moves fast.

─────────────────────────────────────────
LET'S WORK TOGETHER
─────────────────────────────────────────

Send me:
- What you're building
- Your timeline and budget

I'll respond within 24 hours and tell you exactly how I'd approach it.
