AI-powered software, automation systems, and applications built to streamline real business operations Many companies grow faster than their internal systems. Processes that once worked manually start becoming inefficient. Teams spend time entering data, responding to repetitive inquiries, or switching between disconnected tools. I help businesses solve that problem by building AI-powered software, automation systems, and custom applications that connect workflows, automate tasks, and make operations more efficient. My focus is on AI Voice Agents, AI chatbots, AI software, and AI automation systems that integrate with existing platforms such as CRMs, messaging tools, databases, and internal business systems.

I specialize in building strong, dependable Telegram bots that range from simple automation tools to complex AI-powered assistants and complete business solutions. I make bots from the ground up and add them to existing workflows. I also connect them to third-party services and make custom features just for you. Why me: ✔ I know 3 programming languages, which means I can handle any task you need - not just Telegram bots or mini apps. ✔ I take your project from idea to a ready-to-use solution, so you don't need to hire a whole team. You just need me. What I provide: • Custom Telegram bot development from scratch • AI & ChatGPT-powered bots • E-commerce bots - catalogs, carts, payments • Payment systems - Stripe, PayPal • Admin panels and dashboards • Notification & alert bots • Third-party API integrations • Cybersecurity - secure token handling, anti-spam, data protection • Technical support and maintenance Technologies: — Python (aiogram, python-telegram-bot) — Telegram Bot API, Telegram Web Apps — HTML, CSS, Javascript, PHP — Vue.js, Laravel — PostgreSQL, MySQL, MongoDB, Redis — REST APIs, Webhooks — Docker, Linux, VPS deployment

Your AI agent works in the demo and breaks at 100 real users — retrieval was never tuned, the token bill explodes, the architecture buckles. I build agent and RAG systems that hold up in production. 25+ live now, not in a demo folder. 100% Job Success, Top Rated Plus, $300K+ earned, 1,600+ hours on Upwork. Most of the people I work with are founders, CTOs, or ops leads who either need an enterprise SaaS platform built properly for the first time or have a pilot that has stalled and is quietly eating into the budget. I architect and build every system myself, with 16,000+ hours of delivery behind me across healthcare, fintech, SaaS, and real estate, so you're talking to the person who's actually designing your system, not a project manager passing notes back and forth. Most AI projects break in the same place. The demo works great. Then the first hundred real users show up, and things start coming apart: the architecture buckles under load, the token bill gets out of hand, and it turns out retrieval was never really tuned. I build to get past that point. You get a staging environment in week one, a working demo every week, and a system that holds up under actual traffic and clears whatever compliance bar your industry sets. 📊 A few recent production systems: → AI-powered SaaS for the Spanish market (Spring Boot + React) — full multi-tenant platform delivered end-to-end. → AI messaging platform with real-time voice translation. Zero to paying users in 5 weeks. → Multi-agent AI workforce for enterprise ops: four autonomous agents handling inventory, marketing, and operational decisions. → Agentic RAG processing 500+ documents daily for a financial services firm, cutting user discovery time by 93%. → Voice AI for a daycare network. Saved them $24K a year. Built and deployed in 3 weeks. → HIPAA-aware AI triage in a regulated healthcare environment, currently saving the client $300K+ annually. Also in production: RAG assistants for telehealth, LLM-based call analysis across 40+ parameters, AI agents for real estate sales teams, AI knowledge bases for clinicians, document processing for investment analysts, and real-time voice AI avatars for medical education. ⭐⭐⭐⭐⭐ "He did not simply 'deliver a project'—he architected an entire AI-powered SaaS ecosystem from concept to deployment. What sets him apart is his ability to think like both a CTO and a product strategist." — Michael McGehee, Founder & CEO at FreeTrials ⭐⭐⭐⭐⭐ "His ability to bridge strategy and innovation makes him a strong asset for any deep AI/ML-related position." — Louis A. E., CTO at GO, Founder at Web2 Web3 🔧 What I build → AI Agent Development and Multi-Agent Systems with LangChain, LangGraph, CrewAI, and MCP. Workflows with human-in-the-loop approvals, autonomous task execution, and tool orchestration. → RAG Pipelines and AI Knowledge Bases on LlamaIndex, Pinecone, Weaviate, pgvector, and Qdrant. Citation tracking, hybrid search, and the unglamorous retrieval tuning that's usually the difference between a demo and something you can actually ship. → AI Chatbots and Conversational AI on OpenAI, Claude, DeepSeek, Mistral, Llama, and open-source stacks. Conversation memory, escalation rules, and CRM or helpdesk integration. → AI SaaS and MVP Development end-to-end, on React, Next.js, TypeScript, Python, FastAPI, PostgreSQL, and AWS or GCP. → AI Voice Agents on Vapi, Retell AI, Twilio, and ElevenLabs. Real-time processing, appointment booking, CRM sync. → AI Integration and Workflow Orchestration with n8n, Make, and custom Python pipelines connecting LLMs to HubSpot, Salesforce, Zendesk, Google Workspace, and whatever else your team already lives in. →Machine Learning & Predictive Systems — NLP, computer vision, forecasting, and anomaly detection on PyTorch and TensorFlow. ⚙️ How I work Architecture, build, deploy, monitor. I lead the work end-to-end. MVPs go live in 2–3 weeks. Larger enterprise builds are structured around milestones, with weekly demos and a working staging environment from day one. Every deployment ships with CI/CD, monitoring, documentation, encrypted data handling, and 30 days of post-launch support. There's no PM filtering things. 🔒 More than engineering when you need it When a build needs it, I bring in vetted specialists: cloud and DevOps (AWS, Azure, GCP, Docker, Kubernetes, CI/CD), security and compliance (vCISO, SOC 2, ISO 27001, HIPAA, PCI DSS), and dedicated QA automation. You scope, build, secure, and test inside one engagement. 🎓 Credentials PhD in Generative AI and Reinforcement Learning (NUST). MEng in Machine Learning and Deep Learning. AWS Certified AI Practitioner. Upwork Python Skill Certified. 📩 Next step Send me a brief: what you're building, the problem it solves, and your timeline. Within 24 hours, you'll get a technical architecture outline and a straight read on scope. If you'd rather talk first, book a paid Architecture Review, and you'll walk out of the call with a written roadmap.

🎖 Top Rated | 50+ clients | 10+ years building production backend & AI systems You've started building with AI — and the cracks are showing. Hallucinations you can't explain, agents that go off-script, a RAG pipeline that retrieves the wrong context half the time. A demo that impressed everyone and then fell apart on real data. That's exactly where I come in. I build LLM-powered systems that survive production: AI agents, RAG pipelines, and automation built on the data infrastructure they depend on. I work deep in the LangChain/LangGraph ecosystem with Anthropic (Claude API), OpenAI, and open-source models, shipping real products and internal tools for clients in fintech, GovTech, real estate, and edtech. Recent work: • Contract-bidding SaaS for US government procurement — AI agents monitor procurement portals, score opportunities against millions of records, and draft bid responses, cutting manual research time by 80% • Academic integrity platform using LLMs and ML to analyze writing patterns across 50,000+ monthly submissions • Real estate intelligence platform — 60+ concurrent scrapers feeding AI parsing and enrichment pipelines into a multi-region PostgreSQL system Where I spend most of my time: • Designing agent workflows with LangGraph, Make/n8n, and custom orchestration • Building RAG systems that are actually reliable — chunking strategy, retrieval tuning, eval pipelines • Wiring LLMs into FastAPI/Django backends with proper async handling, streaming, and error recovery • Deploying on AWS with Docker/Kubernetes, keeping costs predictable and latency sane at scale The difference: my foundation is 10+ years of backend engineering - Python, FastAPI, Django, PostgreSQL, SQLAlchemy, Celery, Redis, web scraping at scale. I don't just prompt-engineer. Most AI projects fail at the data layer, not the model - I build both. I'm selective about projects. I work best when there's a real problem to solve and a client who wants to understand what they're building, not just receive a black box. If that sounds like you, send me a message with a couple of lines about what you're building.
