Stop wasting human hours on manual data entry, disconnected tools, and administrative bottlenecks.

Whether you need to sync data between your CRM and internal databases, deploy a RAG pipeline to search corporate documents, or build agents that execute multi-step business operations, I deliver maintainable systems that lower operational costs.

🤖 Production-Grade Systems: I design and build AI automation systems that convert manual operational steps into hands-free workflows.
🏆Top-Tier Performance: Backed by a 100% Job Success Score and an Upwork Rising Talent badge, delivering verified performance on every contract.
💻 8+ Years of Engineering: Leveraging over 8 years of software engineering experience to build stable, long-term technical solutions.
🏗️ Scalable Architecture: I do not stitch APIs together with fragile workarounds I architect stable infrastructure from the ground up.
🎯Custom Business Logic: Every system is engineered to match your precise business rules and permanently eliminate repetitive tasks.

⚙️ Core Automation Capabilities

Workflow Automation:
Engineering asynchronous pipelines that capture, qualify, and synchronize data across your software stack.
AI Agents & Enterprise RAG:

API & System Integration:
Connecting disparate applications via webhooks, REST APIs, and database-level integrations to remove data silos.

🛠️ Production-Proven Tech Stack

Orchestration & Logic: n8n, LangChain, LlamaIndex, Flowise
AI & Models: OpenAI API, Anthropic Claude, Llama 3
Backend & Code: Python, Node.js, JavaScript
Data & Infrastructure: PostgreSQL, Supabase, Airtable, Notion, Vector Databases (Pinecone, Chroma, pgvector), Webhooks, REST APIs

💼 What You Get When We Work Together

Independent Execution: Define your high-level business problem, and I will map out the technical design, data flows, and edge-case handling without constant oversight.
Stability Over Temporary Fixes: Every workflow is built with structured error handling, detailed logging, and explicit data mapping so your systems remain functional when an external API updates.
Clear, Direct Communication: I focus entirely on practical business outcomes, providing transparent technical updates and predictable execution timelines.

Let’s connect for a brief discussion to map out your architecture and turn your manual bottlenecks into an automated operational pipeline.
