Turn your business requirements into reliable software solutions with Python
I help growing companies turn complex operational needs into clear, reliable web applications, automated workflows, and data pipelines without losing control.
I start with the problem, not the technology: clarifying requirements, validating assumptions early, and delivering high-impact solutions through clear milestones from design to cloud production.
Core Expertise & Services
Focused on creating business value, reducing technical risks, and delivering maintainable systems.
Scoping & Technical Solution Design
Clarifying business requirements, challenging assumptions, identifying risks, and designing clean, reliable system architectures before writing code.
Custom Python & Web Applications
Building full-stack business applications, REST APIs, and internal tools tailored to your operational processes with Python, FastAPI, Django, React, and TypeScript.
Data Pipelines & Workflow Automation
Engineering robust ETL and reverse-ETL data pipelines, connecting third-party systems (Smartsheet, Dropbox, Odoo), and automating routine manual tasks.
Cloud Infrastructure & AI Integration
Deploying secure, reproducible cloud infrastructure (Azure, Terraform, Docker, CI/CD) and integrating practical AI capabilities (OpenAI API) where they bring real value.
Problem-first approach, milestone-based delivery
I don't start with technology. I start with the problem: What are we trying to achieve? What do we actually need? What's the scope and impact? Then I break the work into small, clear milestones so we learn, adjust, and move forward with total control.
How we work together:
Clarify the core problem, business constraints, and real scope
Challenge assumptions, evaluate risks, and review technical options
Break the work into small, high-value milestones with clear deliverables
Design and build reliable solutions end-to-end (Python, APIs, data pipelines, AI)
Deploy to cloud production, ensure reliability, and iterate on feedback
Professional Experience
Christian RAKOTONARIVO
Python consultant & software engineer helping businesses turn operational problems into reliable software.
With a strong engineering background in materials science (ESPA) and a transition to software development in 2022, I combine analytical rigor with end-to-end engineering. I design and build business applications, REST APIs, data pipelines, and internal tools with Python, FastAPI, Django, React, and Azure. My focus isn't just writing code: I start with the problem, challenge technical assumptions, reduce delivery risks through milestone-based development, and build software that solves the right problem.
