Hi 👋 I'm Vlad, AI developer with 10+ years of experience in engineering. Top Rated on Upwork, $100K+ earned, 2,900+ hours logged. Sound familiar? - Your team spends hours on tasks that could run automatically - You tried an off-the-shelf AI tool - it doesn't fit your workflow - You have a great product idea with AI at the core, but don't know where to start - Your current chatbot answers FAQs but can't actually do anything - You need AI that works with your existing data, tools, and processes - not around them If any of these sound like your situation, here's what I've built for clients in exactly that spot: 💡 AI financial assistant for WealthFluent (Fintech) - Built on Amazon Bedrock + Claude Sonnet. The assistant handles 100% of new user onboarding through conversation, explains portfolio data in plain English, and stays fully compliant with financial regulations. Zero hallucinations on numbers thanks to a hybrid AI + deterministic logic layer. 💡 AI language learning platform for Skrivanek Group (EdTech) - World's largest ISO-certified language school needed an AI-powered SaaS. We built it in 7 months: OpenAI-driven learning assistant, adaptive exercises across 30+ languages, Stripe subscriptions, full user management. Stack: Next.js, LangGraph, LangSmith, PostgreSQL. 💡 AI goal management coach (Productivity SaaS) - Personal coach PWA built in 3 months. AI breaks goals into milestones, sets reminders, tracks progress. Result: 50% faster task execution for users. 💡 AI platform for insurance brokers (InsurTech) - Modernized the UX of an AI-powered broker tool. Saved 1,500+ hours of broker time annually. Redesigned 10+ core workflows, integrated Stripe credit management and document previews. What I build: - AI chatbots that understand context (not just keywords) - AI agents that execute multi-step workflows autonomously - RAG systems that let AI answer from your company's knowledge base - Generative AI features embedded into SaaS products - AI-powered onboarding, support, and automation flows Tech stack: OpenAI, Anthropic Claude, LangChain, LangGraph, Amazon Bedrock, AWS, Next.js, React, Node.js, Python, PostgreSQL, Stripe Industries: FinTech, EdTech, InsurTech, Healthcare, Manufacturing, Logistics Every project starts with: what problem costs you time or money right now? Then we build exactly what's needed - prototype first, production-ready fast. 🏆 "They value clients and their own time. Excellent time management, understood our needs, set realistic expectations." — Arturs Peha, CSO at Skrivanek Let's talk about your project.

Senior Python backend developer with 10+ years building scalable SaaS platforms, REST APIs, and AI-powered systems in Python, Django, DRF, and FastAPI. I turn product requirements into clean architecture, reliable integrations, and production-ready delivery. Need someone to own the backend — from database and API design to LLM integrations and deployment? That's my core strength. I focus on backend-heavy web applications where reliability, maintainability, and business logic matter most, and I help teams fix slow, messy, or hard-to-maintain Python/Django codebases by restructuring logic, stabilizing APIs, and cutting technical debt. I also deliver end-to-end SaaS MVPs — integrations, admin flows, auth, deployment, and collaboration across the full web stack. 𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱: 🟢 SaaS backends and MVPs (Django / DRF, FastAPI) 🟢 REST APIs, webhooks, and third-party integrations 🟢 AI & LLM features — OpenAI, Claude, LangChain, LangGraph, RAG 🟢 Workflow automation and ETL pipelines (Celery, Redis) 🟢 Admin panels, authentication, roles & permissions 🟢 Refactoring & scaling legacy Python / Django systems 🟢 Docker-based deployment, AWS, and CI/CD 𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗵𝗶𝗿𝗲 𝗺𝗲 𝘁𝗼: 🟢 Launch the backend for a new SaaS product 🟢 Stabilize and scale an existing Django application 🟢 Build APIs and integrations that scale reliably 🟢 Automate manual business workflows 🟢 Add AI / LLM functionality to an existing platform 🟢 Get senior-level execution without unnecessary complexity 𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲: Over 10+ years I've shipped products across SaaS, fintech, healthcare, education, and internal business tools. I build modular, well-structured systems that stay easy to extend as your product grows — especially strong in API-heavy platforms, async workflows, and third-party integrations. 𝗖𝗼𝗿𝗲 𝘀𝘁𝗮𝗰𝗸: Python · Django · Django REST Framework (DRF) · FastAPI · PostgreSQL · MySQL · Celery · Redis · Docker · AWS · GitLab CI/CD · REST APIs · Webhooks · Stripe · Twilio · OpenAI · Claude · LangChain · LangGraph · React 𝗛𝗼𝘄 𝘄𝗲 𝘀𝘁𝗮𝗿𝘁: For projects where the scope needs validation, I offer a paid discovery phase — a practical way to align on architecture, priorities, and a delivery plan before a larger engagement. You leave with a clear roadmap, fixed next steps, and no guesswork. If you need a solid Python/Django backend, clean APIs, AI integrations, and senior-level execution with clear communication, send me a message — I'll reply with honest feedback on your project.

Data prep went from 3 days to 30 minutes. 👥 A TEAM, NOT A BOTTLENECK I lead BIGINT Solutions — a Top Rated small team of full-stack developers. One accountable point of contact, the delivery capacity of a small agency. Projects don't stall because one person got sick or took on another client. ⚙️ HOW WE WORK 🔹 Free discovery session — I map your process, pressure-test the idea, and tell you honestly whether AI is the right answer. Some clients leave this call knowing they don't need me yet. 🔹 Architecture and scope — clear technical plan, timeline, and success criteria before any code. 🔹 Build in sprints — working software you can see and use every week, deployed automatically. 🔹Launch and handover — documentation, training, and support so you're not dependent on me forever. 💬 WHAT CLIENTS SAY 🏆 "Ranbeer and his team migrated our BI infrastructure from Azure to Fabric — completed in 2 months, working 100% automatically. A solid basis for migrating all our clients." — Olivier M., Co-Founder & Executive Director 🏆 "More than just an engineer.

If your team needs to understand AI before committing budget, that's a conversation I have often. ✅ Best fit: meaningful engagements where AI makes a real business impact. ❌ Not a fit: maintenance-only work, quick fixes, or legacy patches. Send me your project brief and let's book a free discovery session — you'll leave with a clear technical direction whether or not we work together.

I build and run production full-stack apps, mobile apps, and large-scale scrapers — fast. Top Rated on Upwork with 471 jobs delivered, $700K+ earned, 100% Job Success, and over 10,000 hours in the seat. My edge: I'm an AI-augmented developer. I use modern AI coding tools as a daily co-pilot, which means I ship features and ship them well-tested in less calendar time than a typical full-stack contractor. You get more app per dollar — not because I cut corners, but because I'm at the front of how senior engineers work in 2026. What I'm best at: Full-stack web apps on Cloudflare Pages + Supabase + Next.js / React. Auth, real-time, edge — production from day one. Mobile apps (React Native and native), shipped to App Store and Play Store, with the backend wired to the same Supabase or AWS stack. AWS infrastructure — ECS, ECR, EC2, Lambda, RDS. From a single Docker container to a full Terraform-managed environment. Large-scale web scraping — Python, Playwright, Selenium, rotating proxies, anti-block, dashboards, scheduling. I've built and maintained 15,000+ scrapers and 70+ data-aggregation bots delivering 300K+ data points per minute. High-traffic site operation — building it is one thing, keeping it up at peak load is another. I handle both. How I work: Free 48-hour audit before you hire. Describe your project or share the codebase, and I'll come back with a written plan, stack recommendation, and rough cost. First working version in 14 days for most projects. Clear weekly updates. I don't disappear. I'm the managing partner at Smart Maple, a 12-person software studio, so when projects need a team I can scale up — you still work with me directly as engineer of record. Recent client wins: "Mehmet did a great job from start to finish. He communicated clearly throughout the project, asked the right questions upfront, and delivered exactly what was scoped. No surprises, no chasing." "Mehmet completed his projects on time and to required specifications. I would rehire if needed." "Mehmet and his team did great work for us across 10+ different scrapers, integrated with our chosen backend, and deployed exactly how we needed." Stack I work in daily: TypeScript, JavaScript, Python, React, Next.js, Node.js, React Native, Cloudflare Pages, Cloudflare Workers, Supabase, PostgreSQL, AWS (ECS, ECR, EC2, Lambda, RDS, S3), Docker, GitHub Actions, Playwright, Selenium, Scrapy. Got a project? Send the brief or repo and I'll come back inside 48 hours with a free audit and a clear plan.

Using tools like n8n, Make com, Zapier, and GoHighLevel, I automate: sales and lead management workflows CRM and customer journey automation internal business processes marketing and outreach systems AI-powered decision workflows e) No-Code to Scalable Code Migration: If your product was built on platforms like Bubble, Webflow, FlutterFlow, Replit, or Base44 and has started hitting limitations, I help you migrate it into a scalable, production-grade system. I rebuild your application using modern frameworks like Next.js and robust backend architectures while preserving your existing functionality. At the same time, I upgrade your system for: better performance stronger security long-term scalability clean maintainable architecture Why clients pick me: Most developers integrate an API and call it done. I architect the full system proper error handling, rate limit management, monitoring so it still works when 500 real users hit it, not just in the demo. **Tech Stack** Frontend: React · Next.js · TypeScript · Tailwind CSS · Redux Backend: Node.js · Express · Python · FastAPI · Django · Laravel · GraphQL · REST APIs Database: MongoDB · PostgreSQL · MySQL · Redis · Prisma · Supabase · Firebase AI: OpenAI GPT-4o · Claude API · Gemini · LangChain · AutoGen · CrewAI · LlamaIndex · Pinecone · Weaviate · Hugging Face · Ollama · Claude Code · Vertex AI Automation: n8n · Make com · Zapier · MCP · Webhooks DevOps: AWS · Vercel · Docker · GitHub Actions · CI/CD · Linux VPS **Industries: Fintech · Health tech · B2B SaaS · Marketplace · E-commerce · On-demand · EdTech · Logistics · Legal tech · HR tech · Real estate tech · Travel tech · CRM platforms · Internal tools Got an existing app that needs fixing, scaling, or AI added?
