Professional Experience

Freelance Go & Platform Consultant | Mar 2024 – Present

Client: PerfectStay (Aug 2024 – Mar 2025)

• Engineered a highly resilient Go-based ingestion pipeline processing 1M+ CSV rows in 3 minutes, leveraging AWS Lambda, ECS Fargate, S3 and SQS; achieved zero duplicate processing and replaced manual data entry
• Developed a custom HTTP monitoring service in Go, instrumenting net/http transport to capture latency and errors, reducing diagnostic time from hours to minutes; deployed as AWS Lambda function
• Designed and implemented two Go-based ingestion services integrating external APIs (Giata, TripAdvisor) to enrich and validate data in MongoDB
• Automated AWS infrastructure provisioning for 50+ microservices across three environments using Terraform (Lambda, ECS, S3, Step Functions); established least-privilege IAM policies
• Trained Java and frontend teams on Golang, enabling them to develop and debug Go services independently

Enterprise Training & Consulting

• Delivered enterprise training on Kubernetes architecture and Docker containerization
• Provided e-commerce backend development and consulting (MedusaJS)

Technical Instructor | ESGI (Paris & Lyon) | Sep 2021 – Feb 2024

• Designed and delivered master's-level curriculum on Golang development (syntax, interfaces, asynchronous programming), microservices architecture (gRPC, NestJS), and advanced CI/CD with GitHub Actions for 200+ engineering students
• Guided students in building API-driven Go applications (RESTful User API with GORM, real-time chat service) and comprehensive CI/CD pipelines (automated testing, Docker builds, Vercel deployments)
• Developed hands-on labs for containerized Go microservice deployments, automated testing pipelines, and performance benchmarking on Kubernetes

Parallel R&D (Personal Infrastructure):

• Architected Voc On Steroid microservices ecosystem on GCP: Go/Node.js services, gRPC API gateway, Kong/Traefik routing, multi-database design (MongoDB, MySQL, Elasticsearch), Helm deployments
• Initiated bare-metal Kubernetes cluster: hardware procurement, VM provisioning, initial cluster architecture laying foundation for production-grade HA setup

Fullstack Web Developer | Gymglish → Fastory | Paris | Sep 2019 – Jul 2021

Fastory (Jan 2021 – Jul 2021)

• Engineered a real-time contest leaderboard using Node.js and Redis, handling high-frequency score updates with <100ms latency for thousands of concurrent participants
• Developed a high-performance webhook plugin with Node.js and Hapi.js for efficient chatbot data retrieval, enabling real-time analytics

Gymglish (Sep 2019 – Dec 2020)

• Optimized MongoDB data export pipeline, parallelizing query execution and implementing efficient aggregations to reduce CSV generation time from 15+ minutes to <2 minutes for 100K+ records
• Containerized the application with Docker
• Contributed to Studio V2 platform re-architecture using Python, Flask, and AngularJS to resolve WYSIWYG editor performance issues

Notable Projects

Personal Cloud Platform — Voc On Steroid | Sep 2020 – Present

Self-operated production microservices platform demonstrating full-cycle architecture and platform engineering expertise.

Phase 1: GCP Microservices (2020–2021)

• Architected resilient microservices ecosystem (Go/Node.js) with gRPC for inter-service communication
• Implemented Kong/Traefik for API routing and reverse proxy functionality
• Designed multi-database architecture (MongoDB, MySQL, Elasticsearch) for scalability and independent service deployment

Phase 2: Bare-Metal Kubernetes Infrastructure (2022–2024)

• Architected and operate a production-grade 3-node Kubernetes cluster with HA control plane, MetalLB (layer-2 load balancing), and Cilium CNI
• Implemented GitOps workflow with ArgoCD: deployment time reduced from 1-2 hours to <10 minutes, failure rate from 40% to <5%
• Secrets management with Vault/Infisical via Kubernetes operator for centralized, secure secret handling
• Full observability stack (Prometheus, Grafana, Loki, Jaeger, OpenTelemetry) with custom Go instrumentation for distributed tracing
• Automated node provisioning with Kubespray/Vagrant: cluster rebuild time from 3+ hours to <20 minutes
• Traefik ingress with IngressRoute CRDs for URL-based routing

Phase 3: Architecture Refactor (Current)

• Clean Architecture + Domain-Driven Design (Go)
• CQRS with Command/Query bus for read/write separation
• Dependency injection via Wire
• Multi-environment deployment (dev/prod parity)
• PostgreSQL for relational data layer

Additional: Dreamer — GenAI project, Redis backed realtime capacities, credit system

All project have robust CI/CD pipelines, GitOps deployment, and are running on the self-hosted Kubernetes cluster
