Freelancer profile translated to English.

Description

I work on critical systems where performance, scalability, and cost control are paramount. **AWS Certified Architect (Solutions Architect – Associate)**, I lead complex migrations and design cloud-native or hybrid platforms through a pragmatic approach (Clean & Hexagonal Architecture) that reconciles business requirements and technical reality.

My expertise is structured around three major pillars:

Architecture & Scalability:Design of distributed and highly available systems, modeling of complex asynchronous flows (RabbitMQ, AWS SQS/SNS) and strict isolation (multi-tenancy). I natively integrate a FinOps approach to ensure that technical scaling does not lead to uncontrolled infrastructure costs.
Technical Leadership & Governance:Coaching development teams, defining rigorous technical frameworks, and automating processes. I collaborate closely with DevOps teams to implement automation standards (IaC, CI/CD), thereby optimizing environment management and deployments.
Ecosystem Vision:A cross-functional understanding of the technical stack that enables me to build coherent, maintainable, and reliable systems.

Design of an automated investment platform combining industrial quantitative research and high-fidelity live execution for the institutional market.

Event-driven Architecture | AWS | Serverless | Docker | DevOps | GraphQL | Python | Vue.js | Machine Learning

Core Architecture
Core Architecture:Design of a highly available multi-tenant infrastructure on AWS, capable of supporting 20,000 to 200,000 autonomous trader instances per tenant.
Unified API & B2B Integration:Exposure of a unified GraphQL API facilitating white-label integrations for institutional clients.
Security & Non-Custodial Isolation:Implementation of industry security standards for API key protection through strict permission segregation (trading only, withdrawals blocked), rigorous IP whitelisting, and a dual encryption model (application and infrastructure).

Operational Challenges & Cost Optimization
Market Friction & Fidelity:Alignment of the quantitative lab with market reality by developing a high-fidelity simulation engine that reconstructs the market in continuous flow to capture micro-volatility in order to structurally eliminate backtest drift.
FinOps & Scalability:Fine-tuning of AWS resources and infrastructure consumption to reduce operating costs while maintaining industrial production capacity (generation and execution of 10,000 strategy profiles per month).
Risk Management:Management of availability and fault tolerance through dual protection: an asynchronous static circuit breaker (Hard Stop-Loss pushed directly to the Exchange to prevent infrastructure failure) coupled with a preventive ML algorithm (Trust Score) for real-time de-risking.

Redesign of the onboarding platform architecture to make it modular, scalable, and highly maintainable.

Micro-frontends | Angular | NgRx | Nx Workspace | Typescript | GitFlow

Core Architecture
Micro-Frontend & Monorepo: Design and implementation of a micro-frontend architecture via an Nx Workspace monorepo, allowing the onboarding application to be divided into autonomous and decoupled modules.
State Management: Implementation of centralized and predictable global state management with NgRx, ensuring data flows and synchronization between different micro-frontends.

Operational Challenges & Workflow Optimization
Structural Redesign: Complete restructuring of the existing application to eliminate technical debt, improve loading performance, and ensure long-term maintainability.
Industrialization of Dev Flow: Standardization of development processes by integrating a standardized GitFlow (feature branches) allowing for isolated deliveries and faster code iterations.
Governance & Code Quality: Definition and deployment of strict Clean Code guidelines, ensuring technical consistency within the team and control over deliverable quality.

Design of a multi-tenant infrastructure for unified processing of hybrid transactions (card payments, wire transfers, and loyalty programs) for large retailers.

Event-driven Architecture | RabbitMQ | Microservices | AWS | Spring Boot | Docker | Postgres | MongoDB | Ansible

Core Architecture
Core Architecture & Modularity:Clear separation between client-specific modules and the platform core (core modules). This decoupling helped preserve code integrity and ensure the scalability of the SaaS solution.
API Design & Integration:Alignment and standardization of REST APIs, combined with the creation of an abstraction layer to isolate the platform from the technical specificities of different payment processors and banks.
Architecture Review:Critical analysis of the initial design to adapt it to implementation realities and constraints, thus ensuring the technical viability of the project.

Operational Challenges & Workflow Optimization
Industrialization & Clean Code:Coaching a team of 6 backend developers and standardizing the microservices architecture. Implementing Clean Code guidelines and establishing a rigorous code review process to elevate the overall quality level.
Specifications & Planning:Writing detailed technical specifications and mapping dependencies between backend modules to precisely plan sprints and streamline deliveries.
Infrastructure as Code (IaC):Close collaboration with the DevOps team to optimize AWS infrastructure. Participation in writing Ansible playbooks to fully automate the creation and configuration of our environments.
