✔️ Extensive knowledge of the whole software development life cycle
Over the last 10+ years, my team and I have been building AI-powered products, backend systems, SaaS platforms, and automation tools designed around one simple goal - solving real business problems, not just shipping code.
We’ve worked both as founders building our own products and as a technical partner helping startups and businesses launch, scale, automate operations, and turn ideas into production-ready systems. I work as a Senior Backend Engineer / Python Developer / AI Engineer backed by a full-cycle engineering team covering backend architecture, AI systems, integrations, infrastructure, and product development.
With 10+ years in Python and AI systems, I’ve helped products reach 5M+ users and reduce manual operations by up to 80% for SaaS startups and growing businesses. I build production-ready APIs, automation, and AI platforms that turn ideas into reliable systems.
🤖 HOW I CAN HELP YOU
AI SAAS DEVELOPMENT
Turn your product idea into a scalable AI SaaS platform that can launch faster and support growth without constant rebuilds. I’ve helped deliver MVPs to production in about 6–10 weeks, with systems that have reached $700K MRR and 5M+ users.
AI AUTOMATION SYSTEMS
Reduce manual work and accelerate operations with workflows that handle repetitive tasks, routing, and decision-making automatically. My automation systems have cut operational workload by up to 80% and reduced manual operations by up to 70% in production.
PYTHON BACKEND DEVELOPMENT
Build a backend that stays stable under load, supports clean integrations, and gives your product room to scale. I work with FastAPI and Django on systems processing 100K+ real-time events daily, with architecture designed for concurrency, security, and long-term maintainability.
API INTEGRATION DEVELOPMENT
Connect your product to payments, CRMs, messaging tools, and third-party services so everything works as one system. I’ve built API-driven workflows with Stripe, Google Sheets, Microsoft Graph, Zapier, Make, and n8n to reduce friction and speed up operations.
AI AGENT AND RAG DEVELOPMENT
Add AI assistants that improve support, sales, and internal knowledge access without overwhelming your team. I build LLM, embeddings, and RAG-based systems that have processed 1.9M+ AI interactions in production and improved document and data processing speed by up to 10x.
⚙️ WHAT WE BUILD
🔹 Backend architecture, APIs, databases, AI layers, integrations, and deployment
🔹 SaaS products, AI automation platforms, and internal business systems
🔹 AI agents for operations, support, and sales
🔹 Document processing systems, OCR pipelines, RAG tools, and data extraction
🔹 Real-time systems, messaging platforms, dashboards, and reporting systems
