URGENT HIRE: Full Stack Laravel ReatJs Developer
About MD ABU
AI Engineer and Full-Stack Developer - RAG, LLM Agents, Laravel, React
100%
Job Success
Dhaka, Bangladesh - 2:15 pm local time
ship — backed by 7+ years of senior full-stack engineering (Laravel, React, AWS).
Most "AI developers" stop at a prototype in a notebook. Because I own the full
stack, I deliver deployed, monitored AI products with guardrails, cost control,
and clean handover — not just a demo.
🤖 Recent AI work:
✅ AI Career Portal — CV screening + automated voice interviews (OpenAI, Whisper)
✅ Conversa AI — self-training RAG support bot (Qdrant, LangChain, local Ollama)
✅ Multi-agent dev team — agents that build, test & deliver work via Jira
✅ Vision AI — image scanning that auto-writes titles & descriptions
💡 What I build for you:
✅ RAG chatbots trained on YOUR data (docs, site, KB) — grounded, no hallucination
✅ AI agents & workflow automation (n8n, multi-agent, tool calling)
✅ LLM features in your app — summarize, score, classify, extract, generate
✅ Private local LLMs (Ollama) — zero per-call cost & full data privacy
✅ Scalable SaaS & REST APIs (Laravel, React, Next.js) when you need the platform too
✅ Cloud & DevOps — AWS, Docker, CI/CD, 99.9% uptime
🧠 Technical expertise:
• AI/LLM: RAG, OpenAI, Claude, Ollama, LangChain, Qdrant/Pinecone, vector search,
AI agents, multi-agent orchestration, prompt engineering, vision/multimodal
• Backend: Laravel, PHP, Python, FastAPI, REST API architecture, microservices
• Frontend: React + TypeScript, Next.js, Vue.js
• Cloud & DevOps: AWS, Docker, DigitalOcean, CI/CD (Jenkins, GitHub Actions)
• Databases: MySQL, PostgreSQL, Redis
🚀 Proven results:
• Scaled a SaaS platform (PropSoft.ai) to 50,000+ projects at 99.9% uptime
• Improved system performance by up to 40% through architecture & query tuning
• Built secure banking & government systems with custom payment gateways
• Shipped 12+ AI products end-to-end — from idea to deployed, real-world use
🤝 Why clients work with me:
✔ Senior engineer, not a prompt hobbyist — robust, tested, production-ready AI
✔ One accountable person for the whole stack — data, AI, backend, frontend, cloud
✔ Production-safe by default — cost guardrails, rate limiting, fallbacks, human review
✔ Clear communication, honest scoping, on-time delivery — replies within 24h
✔ Low risk to start — we can begin with a small paid milestone so you see quality first
⭐ Backed by 7+ years of senior engineering, recognized with Best Employee and
Visionary Project Planner awards — known for on-time delivery and repeat clients.
Tell me your use case and I'll reply with a clear plan, an honest estimate, and a
small first milestone so you start with zero risk. Let's build your AI project.
