✅ Top Rated FullStack expert Why Work With Me? 🔹 Top-Rated Focus: I dedicate 100% attention to one project at a time, ensuring quality, timely delivery, and clear communication. 🔹 10+ Years of Impact: Built apps serving 1M+ users, optimized performance by 70% for Fortune 500 companies, and led cross-functional teams. 🔹 Client-Centric Approach: I translate ideas into intuitive, scalable solutions—whether it’s a startup MVP or enterprise-level system. I build the backend infrastructure that AI products run on. Over the past 12 years I have shipped production systems across fintech, insurtech, energy, and AI — from a mobile app with 500K+ downloads in Southeast Asia to a custom RAG pipeline currently running in production at a Stockholm-based AI startup where I serve as Lead Developer. My core work right now sits at the intersection of cloud infrastructure and AI systems — specifically FastAPI backends, custom retrieval-augmented generation pipelines, AWS architecture, and Kubernetes. I have built RAG systems both with LangChain and completely from scratch without any framework, depending on what the project actually needs. On the infrastructure side I work across the full AWS stack — ECS, Lambda, RDS, VPC, IAM, CloudFront — and I am currently leading a Kubernetes migration with zero-downtime deployment strategy at my company. What I do not do is take on five projects at once and disappear. I work with one or two clients at a time, communicate daily, and treat your codebase like my own. If you are building an AI product, a data-intensive backend, or need someone to take ownership of your cloud infrastructure — I am straightforward to work with and I know this stack deeply.

I build secure internal AI copilots and enterprise search systems that connect your documents, CRM, databases, Slack, email, and internal tools so your team can get answers, trigger workflows, and automate repetitive work with confidence. If you need more than a chatbot demo, I can help you ship a production-ready AI system with grounded answers, citations, clean tool integrations, human handoff where needed, and clear evaluation. What I build: • Internal copilots for operations, support, sales, and knowledge teams • Enterprise search / RAG systems over SOPs, policies, contracts, tickets, product docs, and databases • MCP and API integrations for CRMs, helpdesks, Slack, email, Postgres, and internal tools • Workflow automation that updates records, routes tasks, sends follow-ups, and closes manual loops • Evals, tracing, and observability so answer quality improves over time • FastAPI backends, Python services, dashboards, and deployment-ready architecture Common outcomes: • Faster internal answers for teams • Fewer repetitive support tickets • Better lead routing and cleaner CRM workflows • Safer document Q&A with citations • Less manual operational work across disconnected systems I work with: Python, FastAPI, OpenAI, Claude, MCP, PostgreSQL, pgvector, Qdrant, Weaviate, Langfuse, n8n, webhooks, REST APIs, React, and Next.js I do not focus on AI theatre. I focus on useful systems that are measurable, maintainable, and tied to real business workflows. If you already know your bottleneck, send me the workflow and tool stack. If you do not, I can help you design the shortest path to a reliable internal AI system.
