Building a backend is one thing. Building a system that works reliably from API to deployment is another. I'm a Python Backend & AI Engineer and former startup CTO with experience designing, developing, and deploying software systems, from backend APIs and third-party integrations to AI-powered applications. I work with startups, SaaS companies, and engineering teams that need someone who understands both the technical details and the bigger picture. What I Can Help You Build Backend Engineering & API Development - Python, FastAPI, Django, and Node.js - REST APIs, authentication, and third-party integrations - PostgreSQL, MongoDB, Redis, and database design - Background jobs, asynchronous processing, and backend automation AI Engineering & Intelligent Workflows - LLM integrations, RAG pipelines, and AI agents - Function calling, tool execution, and workflow orchestration - Voice-driven AI systems and intelligent automation - Computer vision applications and real-time processing Infrastructure & Deployment - Docker, Linux, and cloud deployments - CI/CD pipelines and backend service configuration - System architecture, performance, and reliability improvements Selected Engineering Projects Voice-to-Action AI Agent Developed the backend for an advanced voice-driven AI automation system connecting user interactions with application actions and external services. NEXTGEN Surveillance & 2WIN Alerts Developed computer vision and alerting systems involving visual monitoring, event processing, and notification workflows. Beyond Writing Code Having worked as a startup Co-founder and CTO, I understand that engineering decisions affect product timelines, maintainability, and business outcomes. My approach focuses on: - Understanding the problem before proposing a solution. - Designing systems that fit the project's actual requirements. - Writing maintainable, structured code. - Communicating technical decisions and tradeoffs clearly. - Delivering tested, documented implementations. Whether you need a new API, a third-party integration, an existing backend fixed, or AI capabilities added to your product, I can help you move from the technical problem to a working solution. Have a backend challenge or integration on your roadmap? Send me a message with what you're building and where you need help. We can discuss the requirements and determine the right approach.
