I build production-ready SaaS platforms and AI-powered systems that launch in weeks and scale for years without the technical debt that forces expensive rewrites later.
Most developers optimize for speed OR quality. I engineer both. With 6+ years shipping SaaS products, I know exactly what to build now versus what to architect for growth.
⚡ My Approach: Launch Fast, Scale Smart:
No over-engineered MVPs with features you don't need. No shortcuts that create problems in 6 months. Every project gets clean architecture, proper security, and infrastructure designed to grow delivered fast.
🛠 What I Build:
- SaaS Platforms & MVP Development
- React, Next.js, TypeScript, Tailwind | Node.js, NestJS, Python, FastAPI
- Multi-tenant architecture • Stripe billing • Auth & RBAC • Admin dashboards
- REST & GraphQL APIs • Real-time WebSockets • Microservices
Cloud Infrastructure & DevOps:
- AWS (Lambda, EC2, S3, RDS, CloudFront) | Docker, Kubernetes, Terraform
- CI/CD pipelines • Auto-scaling • Cost optimization • Monitoring
- PostgreSQL, MongoDB, Redis performance tuning
AI-Powered Applications & Automation:
- OpenAI (ChatGPT), Claude, Gemini | LangChain, LlamaIndex, RAG systems
- Vector databases (Pinecone, Weaviate, Chroma) • AI agents • Chatbots
- N8N, Zapier, Make workflows • Voice agents (Vapi, ElevenLabs)
- Document processing • Embeddings • Intelligent automation
📊 Track Record:
- 50+ SaaS platforms delivered from zero to production
- 15+ MVPs launched in 2-6 weeks with paying customers
- Multi-tenant systems serving 5,000+ daily active users
- AI automation saving clients 100+ hours/week
- Cloud costs reduced by up to 40% through optimization
- 98% on-time delivery with 5-star feedback
✅ What You Get:
→ MVP Launch in 2-6 Weeks (realistic timelines, no false promises)
→ Production-Ready Code (clean, tested, documented, scalable)
→ End-to-End Ownership (architecture → deployment → monitoring)
→ Scalability Built In (grows without expensive rewrites)
→ Clear Communication (daily updates, transparent milestones)
→ Post-Launch Support (I stick around for critical early months)
🎯 Best Fit For:
✓ Non-technical founders launching their first SaaS
✓ Startups adding AI features to existing products
✓ Companies migrating from no-code to custom solutions
✓ Teams needing senior technical leadership + execution
✓ Businesses scaling from MVP to Series A
Not Ideal For:
✗ I work best with clients who value quality, clarity, and realistic timelines.
✗ Constantly changing scope or unclear requirements
✗ Unrealistic timeline expectations
💡 Why Clients Choose Me
I treat your product like it's mine, my reputation depends on your success. I challenge requirements that don't serve users, suggest features you haven't considered, and give you honest timelines even when it's not what you want to hear.
You get a technical partner focused on outcomes, not just closing tasks.
📩 Let's Talk
Send me your product vision, requirements, or existing codebase.
I'll respond within 24 hours with:
- Technical approach and architecture recommendations
- Realistic timeline with clear milestones
- Transparent pricing breakdown
No sales pitch. Just honest technical guidance.

I’m a backend engineer who has recently expanded into AI/LLM systems, combining solid production experience with modern AI-driven development.
I hold a Bachelor’s degree in Electrical, Electronics and Communications Engineering from Hacettepe Üniversitesi, and I’ve been working with a fintech startup (H1 Card) since 2021, where I design and deploy backend systems using Python, FastAPI, and Django on AWS.
Over the years, I’ve built scalable APIs, microservices, and data-driven systems across a range of projects—from fintech platforms to social applications. I’ve worked with technologies like Nameko, Ariadne (GraphQL), Firebase, and Google App Engine, collaborating closely with frontend teams and stakeholders to deliver reliable, production-ready systems.
I’ve also strengthened my engineering practices through the Developing AI Applications with Python and Flask program on Coursera, complementing my hands-on experience building and deploying real-world systems.
More recently, I’ve retooled my skillset around AI and LLMs. I now design and build systems that integrate models like Claude, OpenAI, LLaMA, and Gemini into real-world applications. This includes:
- Building AI agents and multi-step workflows
- Designing systems around MCP (Model Context Protocol) and tool use
- Rapid prototyping (“vibe coding”) and shipping AI-powered features
- Integrating LLMs into existing backend architectures
- Creating chatbots and automation systems powered by modern AI
What sets me apart is that I don’t just experiment with AI—I integrate it into production systems with proper backend architecture, scalability, and reliability.
Some highlights from my experience:
- Backend development for a fintech startup (AWS, FastAPI, Django)
- Built microservices and GraphQL APIs for multiple freelance projects
- Developed complex Django applications, including Mytichaa (an award-winning Messenger bot in the Bots for Messenger Challenge – Middle East & Sub-Saharan Africa)
- Strong background in data handling, APIs, and system design
Core Technologies
- Python (Django, FastAPI, Flask)
- Microservices (Nameko)
- GraphQL (Ariadne)
- Cloud: AWS, Google App Engine
- Databases: PostgreSQL, MySQL, MariaDB, Firebase, Neo4j
AI / LLM Stack
- OpenAI, Claude, Gemini, LLaMA
- AI agents and tool-use systems
- MCP and structured context systems
- Prompt engineering and evaluation
- Backend integration of LLM workflows
What I can help you build
- AI-powered applications and agents
- Backend systems with LLM integrations
- Chatbots and automation tools
- Scalable APIs for web and mobile apps
- Real-time applications (WebSockets, Django Channels)
- Data processing and backend pipelines
I enjoy working on challenging problems and continuously evolving with new technologies. Right now, that means combining backend engineering with AI to build smarter, more capable systems.
If you’re looking for someone who understands production-grade backend systems and modern AI capabilities, I’d be glad to collaborate.
