⚡ Hey, I`m a Full-Stack Engineer | Next.js · NestJS · AI Integration | SaaS & Enterprise Platforms

Building a SaaS product, scaling an existing platform, or integrating AI into your workflow? I help startups and businesses turn complex requirements into reliable, high-performance web applications — on time and built to last.

With 5+ years of hands-on experience, I've worked across the full stack: from pixel-perfect frontends to distributed backend systems and cloud infrastructure. I don't just write code — I think about architecture, maintainability, and the business impact behind every technical decision.

What I bring to your project:

Frontend — React, Next.js, Tailwind CSS, Framer Motion. Responsive, accessible, and fast interfaces that users actually enjoy.

Backend — NestJS, PostgreSQL, Prisma, GraphQL, REST APIs. Scalable services built with clean architecture and fault tolerance in mind (circuit breakers, Redis caching, rate limiting).

DevOps — Docker, Kubernetes, CI/CD pipelines, AWS, Prometheus & Grafana. I ship confidently and keep systems observable.

AI Integration — I design and implement production-ready AI features that solve real business problems, not just proof-of-concept demos. My experience covers OpenAI (GPT-4, Assistants API, function calling, embeddings), as well as third-party services like Anthropic Claude, Replicate, and vector databases (Pinecone, pgvector) for semantic search and RAG pipelines. I've built AI-powered content automation systems, intelligent recommendation engines, LLM-driven chatbots with context memory, and custom prompt pipelines with usage monitoring and cost control. Whether you need to automate repetitive workflows, surface insights from large datasets, or add a conversational layer to your product — I'll help you choose the right tools and implement them cleanly into your existing stack.

Business Systems — SaaS platforms, CRMs, ERPs with role-based access, real-time analytics, subscription management, and payment integrations.

Selected Projects:

🖥️ Streaming Platform (Netflix-style)

Architected the full system from scratch — scalable video APIs, Redis-based caching that reduced load times by ~40%, real-time analytics dashboard, and a fully responsive UI. Deployed and stable for 10,000+ concurrent users.

🖥️AI-Powered Content Dashboard

Integrated OpenAI API into a client's internal platform, automating ~70% of their manual content workflow. Built custom prompt pipelines, usage tracking, and a clean editor interface in Next.js.

🖥️ Multi-tenant SaaS Platform

End-to-end development of a subscription-based SaaS with Stripe integration, role & permission system, user onboarding flows, and an admin analytics panel. Reduced client's operational overhead significantly after launch.

🖥️ CRM/ERP System

Built a tailored internal tool with complex permission trees, task tracking, reporting modules, and third-party integrations — replacing a legacy system and cutting manual reporting time by over 60%.

How I work:

I communicate clearly, ask the right questions upfront, and keep you in the loop throughout the project. I write clean, documented code that your team can maintain long after the engagement ends. Deadlines matter to me — I flag blockers early, not at the last minute.

If you're looking for a technical partner who takes ownership and delivers — not just a developer who completes tickets — let's talk.
