Abdul B.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Oct 27, 2026.

I'm Abdul, a backend and AI systems engineer with 3+ years building production RAG pipelines, LLM-powered features, and scalable APIs for fintech, AI, and SaaS companies. I build systems that hold up under real traffic, not just in a demo. AI & LLM-POWERED BACKENDS RAG pipelines, vector databases, and context-aware AI features using AWS Bedrock and Claude-based workflows, plus the production infrastructure to run them reliably. I focus on the same things that matter in any backend: how it scales, where it fails, and how to architect around that. AGENTIC AI Multi-agent systems and orchestration using tools like Inngest AgentKit, designed for reliable, production-grade autonomous workflows rather than fragile demos. BACKEND & API DEVELOPMENT Python (Django, FastAPI) and Node.js (Express, NestJS) services, REST/GraphQL APIs, async processing with Celery, and event-driven microservices using tools like Inngest, so services communicate through events instead of tight coupling. PAYMENTS & THIRD-PARTY INTEGRATIONS Production experience integrating Stripe and Plaid for platforms handling real financial data. CLOUD ARCHITECTURE (AWS, Azure) AWS Lambda, API Gateway, Cognito, RDS, SNS/SQS, ECS/EKS. Azure for multi-cloud deployments. Docker and Kubernetes for containerized workloads. DATABASES & SECURITY PostgreSQL, MySQL, MongoDB, Redis, vector databases, and Oracle for relational data design. OAuth2/JWT authentication, RBAC, encryption, and access control built in from day one. I communicate clearly, document what I build, and treat every client's code like it's going to production, because it is. If you need a backend or AI systems specialist who can take a project from spec to a deployed, reliable system, let's talk about what you're building.
