Hire the Best Ab Initio Developers

Full Stack Developer with 4+ years building production-grade SaaS platforms, specializing in React, Node.js, Next.js, and NestJS. Currently Tech Lead at RedLizard, owning the end-to-end architecture of a multi-tenant document management platform built from scratch. I work across the full stack from PostgreSQL schemas and NestJS microservices to React/Next.js frontends and I'm comfortable owning infrastructure: deployments on Linux, AWS (Amplify, Elastic Beanstalk), CI/CD pipelines, and third-party integrations. Some things I've shipped: * Built a real-time persistent chat (Firestore) with conversation continuity across workflow stages (bid → contract → active work) on a complex multi-role platform. * Designed a dynamic billing engine with Stripe Invoices: tier-based pricing algorithm for variable driver counts, deferred charge scheduling, and invoice snapshots in PostgreSQL. * Engineered a multi-stage email notification pipeline with scheduler + queue + retry logic for a cross-border real estate platform (US & Canada), handling country-specific identity verification and bank authentication flows. * Replicated a full AWS production environment for staging from scratch: Amplify, Elastic Beanstalk, RDS, SSL, DNS routing.

🏆 Official Odoo Partner | Certified Odoo Team | 50+ Odoo Implementations across Fashion, Real Estate, Textile, Travel, IT, and Manufacturing. I'm Kaushal Gajjar, Founder of 7Span - an Official Odoo Partner agency. I lead a certified Odoo team that delivers production-grade Odoo ERP implementations, customizations, and integrations for global businesses. We work across all Odoo versions, including the latest Odoo 19, and we know which version to put you on (and which to migrate you off of). What I deliver and what most "Odoo experts" miss: ✔ Odoo ERP Implementation (End-to-End): discovery, configuration, data migration, training, go-live, hypercare. Not just install-and-leave. ✔ Odoo Customization & Custom Module Development: Python/XML/OWL/JS, clean code that survives Odoo upgrades. No spaghetti. ✔ Odoo Migration & Version Upgrade: Odoo 13/14/15/16/17 → Odoo 18/19 with zero data loss and minimal downtime. ✔ Third-party Integrations: Shopify, WooCommerce, Amazon, Magento, Stripe, Razorpay, ShipStation, Salesforce, HubSpot, QuickBooks, custom REST APIs, EDI, and more. ✔ Odoo eCommerce, POS, Manufacturing (MRP), Inventory, Accounting, HR/Payroll, CRM, Sales, Purchase, Project, Helpdesk, Subscription, Field Service, Studio ✔ Odoo Functional Consulting & Business Process Mapping: for clients who need a roadmap before they need a developer. ✔ Performance Optimization, Bug Fixing, Server & Hosting Setup: Odoo.sh, AWS, DigitalOcean, on-premise. Why a Partner agency beats a solo freelancer: 🔹 Bandwidth: my certified team can run multiple workstreams in parallel. Backend dev, functional config, and UI/theme can move at the same time. 🔹 Coverage: sick days, time zones, and unexpected scope don't kill your timeline. 🔹 Accountability: you get a documented process, version-controlled code, staging environments, and proper QA, not "trust me, it works." 🔹 Officially backed: direct access to Odoo S.A. for licensing, enterprise support, and roadmap insights. Industries I've delivered Odoo for: Fashion & Apparel, Smart Luggage / D2C, Real Estate, Hotel & Hospitality, IT/SaaS, Manufacturing, Retail, eCommerce, Logistics, Professional Services. 🤝 My promise: if Odoo is wrong for your business, I'll tell you in the first call. If it's right, I'll show you the fastest, cleanest path to ROI. ☎️ Free 30-min Odoo audit Message me with your current setup or business workflow, and I'll send back a specific implementation/migration roadmap before you spend a dollar. Let's build a system that actually works for your business and grows with it.

I build backend systems for fintech, healthcare, and SaaS products where reliability is non-negotiable. My most recent engagement was a US broker-dealer fundraising platform serving 10+ institutional clients — where I owned 5+ backend subsystems end-to-end for over a year, from schema design through Azure deployment. Real financial transactions. Real investor data. Real consequences if something breaks. ──────────────────────────────────── WHAT I HAVE ACTUALLY BUILT IN PRODUCTION ──────────────────────────────────── ✔ Bulk export pipeline — processed 100,000+ investor records via chunked BullMQ jobs with streamed output to Azure Blob. Fully non-blocking API under heavy load. ✔ White-label theming engine — issuer customizations trigger background jobs that compile CSS bundles, save to Azure Blob, and inject via CDN into the frontend, eliminating per-request rendering overhead. ✔ Offering versioning system — complex state transitions, investor eligibility rules, and audit-safe data mutations for broker-dealer flows. ✔ Event-driven notification pipeline — BoldSign digital signing + SendGrid email, unified and fully traceable. ✔ Zero-downtime .NET 7 migration of a live hospital management system — modernized stack, resolved performance bottlenecks, no disruption to healthcare operations. ✔ Ethiopian calendar engine built from scratch — replaced all Gregorian logic across payroll, scheduling, leave, and reporting for a multi-country workforce platform. ──────────────────────────────────── WHERE I ADD THE MOST VALUE ──────────────────────────────────── ✔ You have a backend that works but feels fragile — I find what breaks it and fix it properly. ✔ You need a complex domain built right the first time — payments, workflows, eligibility rules, audit trails. ✔ You need async/background job systems that don't block, fail silently, or fall apart under load. ✔ You need someone who takes full ownership of a subsystem — not someone who needs hand-holding on every task. ──────────────────────────────────── TECH STACK ──────────────────────────────────── Backend: NestJS · Node.js · ASP.NET Core · TypeScript · C# Databases: PostgreSQL · MySQL · SQL Server · MongoDB Async: BullMQ · Redis · Event-driven architecture Cloud: Azure Blob Storage · Azure CDN Realtime: SignalR · WebSockets DevOps: Docker · GitHub Actions CI/CD Auth: JWT · RBAC Integrations: SendGrid · BoldSign · OpenAI API ──────────────────────────────────── IF THIS SOUNDS LIKE YOUR SITUATION ──────────────────────────────────── Send me a message describing your backend problem. I'll tell you directly whether I can help and how I'd approach it — no fluff.
