Hi, This is Elias from Miami. I checked your project description and understand you’re looking to design and implement a central core for 6AM Mart, migrating to a microservices architecture using the Strangler Fig approach. This is a crucial step for enhancing scalability and maintainability. I’ve worked on several similar platforms and understand the key technical challenges involved in such migrations. I would approach this project by first analyzing the existing architecture, then progressively refactoring components while ensuring minimal disruption. I have a few questions to get a better understanding: Q1 – What specific user roles and permissions do you envision for the new system? Q2 – Are there any existing integrations or APIs that we need to consider during the migration? Q3 – How do you plan to handle data consistency and integrity during the transition? I’d be happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hi Adel, I’ve reviewed the 6AM Mart migration to microservices via Strangler Fig. I will design a standalone Core outside 6AM Mart, with secure Keycloak-based authentication, PostgreSQL-first data models, and modular services that can run on separate servers. The plan is incremental: start by replacing the monolith’s core auth and user services, establish robust API contracts, and set up staging/production with proper security, testing, and performance tuning. Phase 1 delivers the Core architecture, Core auth integration, and migration of login and user services, plus end-to-end integration with 6AM Mart and a hardened staging environment, then pen-testing and performance optimizations. Phase 2 will progressively extract modules toward true microservices. I will ensure zero disruption to existing flows, maintain data integrity during migration, and prepare a scalable roadmap for PostgreSQL-based services. What are the critical security and data governance constraints we must honor in the Core authentication layer? Which modules should take priority for Phase 1 extraction beyond login and user services? Do you have preferred service boundaries, API standards (REST/gRPC), or event-driven messaging choices (Kafka/RabbitMQ)? What is the preferred approach for database migration—lift-and-shift of existing MySQL structures to PostgreSQL, or a phased re-architecture per service? Are there any non-functional requirements we should emphasize first (latency targets, error budg

Biggest risk in this migration is replacing the tightly-coupled Laravel core and moving authentication without breaking live API contracts across React, Flutter, and admin/vendor flows—especially under a pre-launch one-month constraint where any auth or order-path regression can block production release. I would introduce an external Core service around Keycloak for identity, with an API gateway preserving current contracts while gradually strangling legacy endpoints. Laravel monolith stays stable while routing shifts via adapter services and feature-flagged endpoints. PostgreSQL migration uses dual-write/read strategy with schema parity checks to prevent drift. Staging mirrors production for safe cutovers, with integrated penetration testing before rollout. I’ve implemented similar distributed API migrations in Bubbl (Laravel/Nuxt SaaS) improving API latency by 35% and Aras backend systems with zero-downtime refactors under heavy traffic. Ready to align architecture with your PDF and ensure Phase 1 is production-safe and reversible at every step. Phase 1: $8,000–$12,000 | Phase 2: $15,000–$25,000 | Support: 60–90 days post-launch Q1: Which specific endpoints in the current Core are most critical and must remain stable during strangler routing? Q2: Do you already have a preferred API gateway standard (or should we introduce one alongside Keycloak)? Q3: What is the expected cutover strategy for disabling the internal Core—hard switch or gradual deprecation per module?

@kamran2012

Good to see this project, I will deliver the Phase 1 Core — Keycloak-based authentication, User Service, API gateway, and full integration with 6AM Mart — following the Strangler Fig pattern so the monolith keeps running while each service is extracted behind a façade. For the migration, I will introduce an anti-corruption layer between the new Core and 6AM Mart's existing Laravel backend. This layer translates requests so both systems coexist during transition, and it gives you a kill switch to route traffic back to the monolith instantly if anything breaks in production — critical given your one-month launch window. Questions: 1) How far along is the MySQL-to-PostgreSQL migration — is the schema already converted, or will Phase 1 need to handle dual-database reads? Looking forward to your response. Best regards, Kamran

@Srashtasoft

Hi there, I have read your project requirement. You need to transform your existing 6AM Mart monolithic system into a scalable microservices architecture using the Strangler Fig approach, including building a centralized Core (with Keycloak authentication), PostgreSQL migration, system integration, and production-ready deployment without disrupting current functionality. We can design and implement a robust Core architecture, decouple critical services, integrate authentication across all panels, and prepare the system for gradual microservices extraction. The solution will include clean API contracts, staging/production environments, performance optimization, and security testing aligned with your launch timeline. A few questions to clarify before proceeding: =================================== Do you prefer containerized deployment (Docker) or direct VM-based services for Phase 1? Should we include an API Gateway layer (Kong/Nginx) in the initial setup? Do you want event-driven architecture (Kafka/RabbitMQ) introduced in Phase 1 or later? Which module should be prioritized first for extraction in Phase 2? Best Regards, Srashtasoft Team

@salmanullahbaig

Read your brief carefully and this is right in my wheelhouse. The 6AM Mart system's current monolithic architecture and the plan to migrate to a microservices architecture using the Strangler Fig approach is a complex task that requires careful planning and execution, and I've worked on a similar project where I had to refactor a legacy e-commerce platform to a service-oriented architecture. The fact that the system includes multiple modules such as Food, Grocery, and Pharmacy, and that you're migrating from MySQL to PostgreSQL, indicates a significant undertaking. I noticed that the project requires building a standalone Core that will act as the central hub of the system, and that all panels and applications must authenticate through this Core. What's the expected timeline for completing the migration to PostgreSQL, and how will it impact the development of the new Core. Let's discuss how I can help with this project. Happy to share more about my approach — just send me a message.

Hello Adel Abdullah, I understand the complexity of transitioning the 6AM Mart system into a Microservices architecture using the Strangler Fig pattern. The current monolithic architecture poses challenges that require a strategic approach to ensure a seamless migration without disrupting system functionality. To achieve this, I propose developing a standalone Core outside of 6AM Mart, serving as the central hub for the system. By gradually separating components into independent services, we can transform the system into Microservices progressively. This approach will enhance scalability and maintain system stability. With expertise in Software Architecture, PostgreSQL, Laravel, and Microservices, I am well-equipped to design and implement the necessary infrastructure. I will focus on building a secure, high-performing Core, integrating authentication systems, and optimizing performance. I have reviewed the project details, PDF, and source code, and I am confident in my ability to deliver a successful Phase 1, meeting all specified criteria.
