LEOZIN | 6amMart Hybrid B2B + B2C Core Logic Customization -- 2

@jafarali14

Hi Manish, I am a Laravel & Flutter developer with 9+ years of PHP experience, with strong experience modifying existing Laravel codebases, Flutter apps, APIs, payment integrations, inventory workflows, GST-related logic, and admin systems. Your LEOZIN customization is exactly the type of work I handle—deep changes to an existing platform while preserving its current architecture and buyer/seller flows. **My approach:** I’ll work directly inside the existing Laravel services and Flutter provider architecture, first mapping the current flows before modifying them. I can implement the B2B GST lock, Circle-Zone delivery rules, runsheet rider authentication, separate Wholesale/Retail admin roles, Razorpay/Cashfree selection, GST/HSN/SAC invoices, and bulk inventory with pack-size, MOQ and FIFO logic. I’ll update affected APIs, add tests for critical paths, and validate Android, iOS and Web builds. I understand the **7-day delivery requirement** and can prioritize the listed pillars for rapid incremental delivery without unnecessary setup work. If you share the existing 6amMart codebase or a representative module, can we review the highest-risk logic first and confirm what can realistically be completed within the 7-day window?

Dear Manish Kumar, I understand the need to reshape the 6amMart code-base into "LEOZIN" to cater to both wholesale (B2B) and retail (B2C) customers. With my expertise in PHP, Laravel, MySQL, Flutter, and API integration, I have successfully handled similar projects in the past, as showcased in my portfolio. To achieve the desired outcomes for "LEOZIN," I will focus on enforcing mandatory GST-number lock for B2B sign-ups, building a Circle-Zone delivery engine for B2C orders, implementing a runsheet-based credential flow for delivery riders, and integrating payment gateways like Razorpay and Cashfree seamlessly. My approach involves integrating these functionalities within the current architecture, updating API documentation, and ensuring smooth builds for Android, iOS, and Web platforms. I am committed to delivering high-quality results within the specified timeframe. Let's discuss how I can add value to your project further. Best regards,

Hello Manish, I am an experienced Laravel and Flutter developer with strong expertise in modifying existing applications with complex business logic and third-party integrations. I can reshape your existing 6amMart codebase into LEOZIN without disturbing the current buyer/seller functionality. I can handle GST-based B2B registration, Circle-Zone delivery, runsheet rider authentication, and separate B2B/B2C admin dashboards. I can also implement Razorpay + Cashfree, GST-ready invoices, HSN/SAC, tax calculations, pack-size/MOQ and FIFO inventory logic. I will maintain the existing Laravel service and Flutter provider architecture and update APIs/documentation where required. I will also cover critical workflows with proper unit/feature testing and verify Android, iOS and Web builds. I am ready to start immediately and can work with your 7-day delivery timeline. Looking forward to discussing the complete specification with you.

Hi Manish, I’m Karthik, a seasoned developer with over 15 years of experience in Laravel and Flutter. I understand you need significant customization for the 6amMart codebase to create LEOZIN, catering to both B2B and B2C clients. I can enhance your platform by implementing the required core logic changes, including: - Mandatory GST-number verification for B2B sign-ups. - Development of a Circle-Zone delivery engine for B2C orders. - Credential flows for delivery riders based on runsheets. - Separate dashboards for Wholesale and Retail with tailored roles. - Integration of Razorpay and Cashfree at checkout. - Generation of GST-ready invoices with compliance to HSN/SAC. - Advanced inventory management tools for bulk orders. I assure clean integration with existing Laravel and Flutter structures, updated API documentation, and thorough testing to meet your acceptance criteria. My commitment is to deliver within the 7-day window with high-quality output. Feel free to check my profile for previous modifications on 6amMart instances. Looking forward to your response. Best, Karthik

Hi Manish, I can customize the 6amMart Laravel backend and Flutter apps for LEOZIN without disturbing existing buyer or seller flows. I’ll first map the current services, APIs, and Flutter providers, then implement the B2B GST lock, Circle-Zone delivery rules, rider flow, dashboards, payment gateways, and inventory logic in clear milestones. I’ll keep API documentation updated, test the critical flows, and validate Android, iOS, and web builds before handover. Please share the current 6amMart version, branch, and remaining pillar specification so I can confirm the final delivery plan.

Hi there, I’m excited about the opportunity to transform the 6amMart code-base into LEOZIN. With my extensive experience in Laravel and Flutter, I’ve tackled similar projects where deep edits were crucial for seamless performance. You can count on me to enforce that mandatory GST-number lock and create a Circle-Zone delivery engine that enhances the user experience. I noticed you’re looking for a split admin experience with dedicated dashboards for both Wholesale and Retail. That’s right up my alley, and I can ensure everything remains clean and professional throughout the process. I specialize in core logic customization and integration, so you can trust me to deliver robust features like the Razorpay and Cashfree integration, alongside advanced inventory tools. I’m committed to speedy communication and can guarantee a fast turnaround within your 7-day window. Let me know if you are available for a quick chat! Regards, Wonita

Hi Manish, New on Freelancer — 20 years of development experience behind us. We're taking our first few projects here at a fraction of our normal rate purely to build our review history. You get senior agency work at junior pricing; we get a review. Straight trade. Given the complexity of reshaping the 6amMart code-base into LEOZIN, it's crucial to ensure the Laravel backend integrates smoothly with the Flutter apps for both B2B and B2C functionalities. A potential risk to watch for is maintaining data consistency during the payment processing customization. Could you provide access to the current code repository so I can evaluate the initial setup?

You want 6amMart gutted and rebuilt as LEOZIN — a production-grade hybrid B2B/B2C platform with GST compliance, dual dashboards, zone-driven delivery, and two payment gateways wired together cleanly, without touching existing buyer/seller flows. My plan: start with a domain audit of the current service layer, then build in this order — GST lock + B2B auth, Circle-Zone engine, dual admin split with RBAC, Razorpay/Cashfree checkout abstraction, runsheet rider auth, GST invoice generator with HSN/SAC, then FIFO inventory and pack-size logic. Every change lives inside existing Laravel services and Flutter providers. API docs updated per endpoint. Clean compile guaranteed before handoff. I work in Laravel and Flutter daily, have handled multi-tenant RBAC splits, payment gateway abstractions, and GST invoice logic with HSN rounding rules on live codebases. I read unfamiliar code fast and write zero throwaway code. Realistic timeline: 6-8 weeks depending on the remaining pillars you mentioned. I'd rather scope accurately than promise fast and deliver broken. One question before I size this properly — how many additional pillars are there, and do you have existing database schema docs or ERDs I can review now?

Your requirement is clear: this isn’t a new build or setup job — the existing 6amMart Laravel + Flutter architecture needs to be reshaped without breaking the current buyer/seller flows. I can work directly inside the existing service/provider structure and handle the changes at code level, including: • GST-locked B2B registration • Circle/Zone delivery rules and slot visibility • Runsheet-based rider authentication • Separate Wholesale/Retail admin roles and menus • Razorpay + Cashfree checkout/refunds • GST/HSN/SAC invoice logic • Bulk inventory, MOQ, pack-size and FIFO deduction • API updates + critical-path testing I’d first map the affected Laravel services, Flutter providers and database relations so the modifications stay isolated instead of turning into patches across the codebase. I won’t claim a public 6amMart production instance if I can’t provide one. What I can provide is clean implementation, updated APIs, tested builds and a structured delivery against your acceptance criteria. 7-day delivery window works for me. Share the remaining twenty-pillar specification and I can identify dependencies before touching the core flows.
