Built something with Lovable, Replit, v0, Cursor, or Claude Code but now need it cleaned up, connected, deployed, or made production-ready? That is exactly where I can help. I am a Senior Software Engineer working on Upwork for more than 13 years as a Full-Stack Expert. I work with founders and small teams who have an idea, prototype, broken MVP, or AI-generated codebase and need a real engineer to turn it into a stable product. I can fix the backend, connect the database, add authentication, implement Stripe, improve UI, clean the code, deploy the app, and make sure the system works for real users. What I help with ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1) Turning AI-generated prototypes into working apps 2) Fixing broken Lovable, Replit, v0, Cursor, or Claude Code projects 3) Building AI SaaS apps, chatbots, agents, and automation workflows 4) Adding Supabase, PostgreSQL, Firebase, auth, roles, and dashboards 5) Implementing Stripe Checkout, subscriptions, webhooks, Connect, and payouts 6) Connecting APIs, CRMs, email, SMS, storage, AI models, and third-party tools 7) Cleaning messy code and making the app easier to maintain 8) Deploying to Vercel, Render, VPS, AWS, GCP, or Docker-based setups I’m a Top Rated full-stack developer with $100K+ earned, 179 Upwork jobs, and 6,800+ hours delivered. I’ve worked across web apps, mobile apps, SaaS platforms, Stripe systems, AI integrations, dashboards, automations, and backend-heavy products. I use AI tools daily to speed up development, but I do not blindly ship AI-generated code. I review, restructure, test, and handle the important parts myself: data flow, payments, API logic, authentication, permissions, security, and deployment. Best fit: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ - You have a prototype but it is not production-ready - You need an MVP built quickly but properly - Your app works in demo but breaks in real usage - You need someone who can explain technical problems clearly - You want a developer who can own the build without constant hand-holding My goal is to help you move fast without creating a technical mess that becomes expensive later. Share what you have built or what you want to build, and I’ll tell you clearly what needs to be done, what can be reused, and what should be fixed first.

I am an AI and Backend Engineer with 5+ years of experience building production-ready backend systems, AI-powered products, Discord and Telegram bot, and real-time automation platforms. I have shipped 30+ production systems serving 5,000+ daily active users across fintech platforms, trading systems, crypto tools, P2P services, membership communities, and moderation systems. Every system I build is engineered to survive edge cases, scale under load, and remain stable long after deployment. 🛠️ What I Build: → AI-Powered Telegram and Discord bots for community management, business workflows, role-based access, automation, and moderation → AI agents and chatbots with LLM integration, RAG pipelines, persistent memory, multi-turn context handling, MCP server integration, and tool calling built with LangChain, CrewAI, and OpenAI/Anthropic APIs → Scalable backend APIs and microservices built with Python (Django | FastAPI), Node.js, and Golang covering REST, WebSockets, and Webhooks for high-performance production systems → Fintech backend systems with wallet management, ledger logic, transaction processing, audit trails, and financial data pipelines → Real-time systems using Redis pub/sub, WebSockets, event-driven architecture, and async task queues for high-throughput workloads → Microservices architecture with Docker containerization, service isolation, and independent scaling for long-term maintainability → Crypto exchange integrations and trading bot development, on-chain wallet events, and real-time market data execution → Database architecture and optimization across PostgreSQL, MongoDB, and Redis designed for high-throughput production workloads → Cloud deployment and infrastructure on AWS including EC2, Lambda, S3, RDS, and API Gateway for production grade systems 🏗️ Engineering Approach: Every system I deliver is tested under real conditions, documented clearly, and handed over in a state you can maintain and scale without calling me back to fix it. If you need someone who understands production-ready backend engineering to build your backend system, AI product, or Telegram bot, send a message and I will get back to you within a few minutes.

Need AI added to your app, a workflow automated, or an MVP finished? I can help you scope it, build it, and ship it without overcomplicating the first milestone. I build AI products that survive real users, real data, and real business workflows: SaaS MVPs, AI agents, RAG systems, voice AI, and automation inside existing products. ⭐ Top Rated Plus | Top 3% of performers on Upwork ✅ 10+ years building SaaS and AI products | 100+ projects delivered ✅ AI that ships: RAG, AI agents, MCP, Voice AI, LLM integration ✅ Full stack: Next.js, React, TypeScript, Python, Node.js, PostgreSQL, AWS ✅ SaaS, MVPs, automation, fintech, healthcare, construction, legal tech, and sales products You can hire me when: - You need one AI feature added to an existing app - You want OpenAI, Claude, Gemini, or MCP integrated into your product - You need a RAG system over PDFs, documents, knowledge bases, or internal data - You want a voice AI agent for calls, bookings, lead qualification, or CRM updates - You have a workflow involving documents, calls, follow-ups, data entry, or reporting that should be automated - Your MVP is half-built, buggy, slow, or stuck before launch - You need someone to build a full SaaS product from idea to deployment I work well on both small and large projects. If the right first step is a quick audit, prototype, bug fix, integration, or one-week milestone, I will tell you that. If the project needs a full build, I can own the architecture, frontend, backend, AI layer, deployment, and documentation. The part most AI freelancers skip: AI is rarely the whole product. It usually needs a backend, dashboard, auth, billing, permissions, logs, human review, and deployment around it. I build both the AI layer and the product around it. WHAT I DO: - AI SaaS & MVP builds: idea to deployed product with auth, billing, dashboards, and AI layer - AI inside existing products: RAG, agents, MCP, LLM features, document AI, and automation - Voice AI: agents that answer calls, book appointments, qualify leads, and log to your CRM - RAG and document AI: source-grounded answers, OCR, extraction, citations, and review queues - Workflow automation: documents, follow-ups, data entry, reporting, and API integrations - Rescue & ship: half-built MVPs refactored, hardened, and launched RECENT DELIVERIES: - AI sales CRM: call transcription, follow-up automation, multi-tenant pipelines - RAG document platform with every answer cited to source - AI financial intelligence platform: open banking + accounting sync into one ledger - AI voice agents for healthcare and sales, answering real calls daily - Turnkey B2B SaaS platform for the construction industry, end to end HOW I WORK: - I start by understanding the workflow, users, data, and business goal - I suggest the smallest useful first milestone when possible - I scope clearly before code is written, so you know cost and timeline up front - I can work on focused tasks, short prototypes, rescue work, or full product builds - I work full time on Upwork with overlap for US and European business hours If you need one AI feature, a quick prototype, a stuck MVP fixed, or a full SaaS product built, send me a short description of what you have and what you want it to do. I will reply with the clearest next step, the likely scope, and the first milestone I would recommend. Tech Stack: AI and LLM: OpenAI, Claude, Gemini, LangChain, LangGraph, CrewAI, MCP, function calling, model routing RAG and vector search: RAG pipelines, embeddings, semantic search, pgvector, Pinecone, document AI, OCR AI agents and automation: multi-agent systems, AI copilots, workflow automation, document extraction with review queues AI reliability: evaluation sets, hallucination reduction, human-in-the-loop workflows Voice AI: Vapi, Retell, ElevenLabs, Deepgram, OpenAI Realtime, Twilio Frontend: Next.js, React, TypeScript, Tailwind CSS, React Native Backend: Node.js, Python, FastAPI, REST and GraphQL APIs, WebSockets Databases: PostgreSQL, Supabase, Redis, MongoDB SaaS architecture: multi-tenant, tenant isolation, RBAC, Stripe billing, admin dashboards Cloud and DevOps: AWS, Docker, Vercel, CI/CD, monitoring Security and compliance: OAuth2, JWT, encryption, audit logs, HIPAA-aware builds, KYC/AML flows Integrations: Stripe, Plaid, open banking APIs, QuickBooks, Xero, Twilio, CRMs, ERPs Industries: AI SaaS, AI agents, document AI, RAG, FinTech, open banking, healthcare, B2B SaaS, startup MVPs, construction tech, legal tech, sales and CRM automation, voice AI, recruiting
