I am Chabel Holdo Bossa, a remote-first Backend & Full-Stack Software Engineer from Benin building production-grade software across web, mobile, desktop, SaaS platforms, automation systems, and AI-powered workflows.

My strongest base is software engineering: TypeScript, NestJS, Spring Boot, React, React Native, PostgreSQL, APIs, product architecture, and real-world delivery.

My AI systems work focuses on connecting backend systems with LLMs, automation, transcription, data workflows, retrieval, evaluation, and applied mathematical reasoning.

I do not just write screens and endpoints. I connect product thinking, clean architecture, data modeling, user experience, and delivery discipline until the system works in the real world.

Give me a messy product problem. I will turn it into flows, APIs, interfaces, data models, automations, and systems people can trust.

I work at the intersection of backend engineering, applied AI, data systems, and mathematical modeling.

I do not use AI as a buzzword. I focus on the engineering work required to make AI useful inside real products: reliable APIs, structured data flows, model integrations, automation, evaluation, monitoring, and business workflows.

I am especially strong in roles and projects where backend engineering meets AI:

• AI-powered SaaS products
• LLM applications and agentic workflows
• backend systems for automation
• data-driven business platforms
• fintech, payments, risk, and fraud automation
• product engineering with strong technical ownership

The positioning is deliberate: backend/full-stack ownership with AI systems, automation, and applied mathematical reasoning built into the product architecture.

Most of my serious work is private because it belongs to clients, startups, or active products. I protect client confidentiality: no private screenshots, no client-owned source code, no sensitive technical architecture, and no details that can expose a partner or customer. The public GitHub is the surface. The shipped systems are the proof.

1. Clarify the product goal before touching the code.
2. Design the smallest architecture that can survive real usage.
3. Build interfaces that feel obvious, fast, and trustworthy.
4. Keep APIs predictable, documented, and easy to extend.
5. Optimize for delivery without sacrificing maintainability.
6. Communicate clearly, especially when the problem is still blurry.

I like software that feels calm on the outside and disciplined on the inside: clean UX, readable code, strong data flow, and architecture that does not collapse when the product grows.

I am a strong fit for teams that need someone who can move across the stack while still caring deeply about architecture, product quality, and real-world delivery.

• You need a backend engineer who can design APIs, business logic, data models, integrations, and reliable services.
• You need a full-stack engineer who understands frontend, mobile, backend, and product constraints.
• You need someone who can work on SaaS platforms, dashboards, automation systems, payment workflows, and internal tools.
• You need an engineer who can contribute to AI-powered products, LLM integrations, automation, and AI systems engineering.
• You need someone comfortable with remote collaboration, ownership, execution speed, and technical communication.

The best conversations to have with me:

• Designing NestJS or Spring Boot APIs.
• Building SaaS products from zero to usable.
• Creating polished React, Next.js, Angular, or React Native interfaces.
• Integrating payment systems, messaging tools, dashboards, and business workflows.
• Connecting AI models to real products through APIs, automation, transcription, and structured workflows.
• Turning a rough idea into a real product plan.

If the work above matches what you are building, the fastest path is simple:
