Need to build an AI system over your data (RAG, LLM workflows, automation) — not just a demo, but something that works reliably in production? I design and deliver AI-powered backend systems: RAG pipelines, LLM apps, semantic search, and automation integrated with real business data (APIs, databases, documents, search indexes). Recently, I’ve built systems combining OpenAI / Anthropic / DeepSeek with Pinecone, OpenSearch, Snowflake, PostgreSQL, LangChain, and async pipelines (Celery) for knowledge search, lead processing, messaging, analytics, and automation workflows. 16+ years building production SaaS, high-load APIs, and data-heavy systems. --- 🤖 AI Systems & LLM Work - RAG pipelines over structured + unstructured data (embeddings, vector search, semantic search, contextual answers) - OpenAI-powered knowledge assistant using embeddings + Pinecone vector retrieval + context-aware prompt construction - LangChain SQLDatabaseChain integration for PostgreSQL-backed fallback retrieval - LLM-powered workflows (prompt pipelines, structured outputs, streaming responses) - Real-time streaming AI chat using Django StreamingHttpResponse / SSE-style responses - AI integrated into production systems (Celery, async jobs, retries, batching, monitoring) - Model routing with company/prompt-level fine-tuned model support and fallback handling - Real-world use cases: enrichment, classification, messaging automation, Q&A, data processing --- 🧠 What I can build for you - RAG systems over your internal data (documents, databases, search, QA, assistants) - AI-powered knowledge assistants and semantic search tools - LLM-powered automation (lead processing, emails, enrichment, classification) - Internal AI tools for operations, support, analytics, and data workflows - Backend systems integrating LLMs into real production workflows (not isolated scripts) --- ⚙️ Backend, APIs & System Design - Python, Django, Django REST Framework, FastAPI - API design, auth, permissions, business logic orchestration - Webhooks & integrations (Stripe, SendGrid, Nylas, Zapier, OpenAI, etc.) - High-load async systems (Celery + Redis, queues, retries, scheduling) - Production-safe error handling, fallback logic, logging, and debugging --- 📊 Data, Search & RAG - PostgreSQL/Aurora, Snowflake - OpenSearch / Elasticsearch, Pinecone - Embeddings, vector search, semantic search, context retrieval - Data modeling, ETL pipelines, complex SQL, performance tuning - Enrichment, deduplication, segmentation, scoring systems --- ☁️ Infrastructure & Delivery - AWS (S3, Lambda), Docker, Nginx - CI/CD, production deployments, monitoring - Reliable systems for high-throughput and data-heavy workloads --- 🖥️ Frontend (when needed) - React, TypeScript - Dashboards, admin tools, API-driven interfaces - Frontend integration with AI-powered backends and streaming responses --- 🎓 Applied Mathematics & Computer Science Background - Mathematical modeling of real-world systems - Probability, statistics, numerical methods - Optimization, algorithms, system-level thinking This foundation helps design efficient, scalable AI systems (RAG, pipelines, search, data workflows). --- 📜 Certifications & Learning - Generative AI for Software Developers Specialization - LangChain for LLM Application Development - Claude Code in Action (Anthropic) - RAG / AI Systems / AWS certifications in progress --- I focus on building systems that actually work in production — reliable, scalable, and aligned with real business workflows.
