Backend & API Integration Engineer focused on Python, REST APIs, connector development, AI infrastructure, distributed systems and integration reliability.
I build and validate backend integrations connecting external services, APIs and data sources. My work covers API authentication, data transformation, error handling, webhooks, data synchronization, integration testing, debugging, CI workflows and Docker-based reproducible environments.
I contribute to open-source infrastructure projects including Apache SeaTunnel, AIBrix/vLLM Router and OpenTelemetry C++. My contributions involve connector validation, distributed-system integration, repository debugging, testing, CI reliability and deterministic/reproducible engineering, including implementation changes refined through maintainer review.
Core capabilities:
• Python backend development
• REST APIs & third-party API integration
• MCP servers & AI tool integration
• Connector development
• Authentication & API error handling
• Webhooks & data synchronization
• Distributed systems & data infrastructure
• Integration testing & debugging
• Docker & reproducible environments
• CI/repository engineering
• Git/GitHub & open-source workflows
• Technical documentation
I am particularly interested in clearly scoped engineering work where an existing product needs a new connector, API integration, MCP tool/server capability, backend service, reliability improvement or reproducible technical fix.
Available for remote B2B and freelance engagements through PAMILANGA LIMITED. I can work with defined acceptance criteria and deliver implementation, tests, documentation and clean GitHub-based handover.
