About Ali
Java Backend Developer | Spring Boot | Fintech APIs
Lahore, Pakistan - 2:12 am local time
With 9+ years of backend engineering experience, I build and modernize Java/Spring Boot systems for fintech, payments, insurance workflows, wallets, and enterprise platforms.
Some relevant results include scaling payment processing from 1 TPS to 200 TPS, reducing insurance workflow processing time from 4 - 5 hours to 30 - 40 minutes for 1000+ records, building wallet/payment APIs, working with ISO 8583 integrations, and modernizing legacy platforms into Java-based microservices.
I also help teams automate repetitive work with n8n and connect AI into backend systems in a practical way, with proper validation, audit trails, and human approval where needed.
What I can help with:
➞ Payment, Wallet & Fintech Systems - Payment workflows, MyABL Wallet/payment flow experience, Mastercard/MasterPass QR integration, transaction routing, sandbox coordination, ISO 8583 integrations, third-party payment APIs, and secure financial data handling.
➞ Java Spring Boot Backends - REST APIs, microservices, modular backend architecture, secure business logic, authentication workflows, and production-ready backend systems.
➞ Enterprise Modernization - Insurance workflow modernization, legacy system improvements, requirement grooming, and converting business requirements into automated Java/Spring Boot workflows.
➞ Enterprise & SaaS Workflow Automation - n8n and backend API automation for lead/support workflows, human approval flows, automated notifications, CRM/API integrations, SaaS-ready automation workflows, and backend-connected business process automation.
➞ Real-Time Backend Systems - CiscoJTAPI-style integrations, WebSockets, agent,team monitoring, live updates, backend event handling, and operational system integrations.
➞ Database & Performance - PostgreSQL, MySQL, MSSQL, Firebase, Redis, SQL optimization, query tuning, and backend performance improvements.
➞ AI Integration inside Backend Systems - RAG document assistants, AI ticket triage, structured LLM outputs, validation, audit trails, human review, prompt/model comparison, LLM evaluation workflows, and AI recommendation services.
➞ DevOps & Production Support - Docker, GitLab CI/CD, Jenkins, GitHub Actions, deployment workflows, release support, and backend troubleshooting.
Looking for someone to build or improve your Java/Spring Boot backend? I can help with secure APIs, payment workflows, automation, and practical AI integrations. Let’s talk about what you’re building.
