Project details
I build production-ready REST APIs using Java 21 and Spring Boot, the kind that actually hold up under real traffic, not just demo conditions. My background is 5 years in FinTech, building payment systems and backend infrastructure for clients like Payoneer and Bank of Canada at i2c Inc.
What you get isn't just working code. It's clean architecture, proper error handling, input validation, and documentation that another developer can pick up without calling you. Every project is delivered via GitHub with a clear readme and tested endpoints.
If you need a backend that's built right the first time, that's what I do.

About Muneeb
Java & AI Backend Engineer | FinTech | Spring Boot | ML Integration
Islamabad, Pakistan - 5:02 am local time
At i2c, I worked on core banking systems, cardholder management platforms, payment processing APIs, security testing, and performance testing across web and mobile applications handling billions of transactions worldwide.
I currently build enterprise backend systems at Elixir Technologies for a Customer Communications Management platform serving clients in healthcare, automotive, and financial services including USAA.
Beyond core Java work, I've built and deployed ML systems in live banking environments. At i2c I designed LogSecure, a hybrid BERT + XGBoost NLP pipeline that detected PII and credential leakage in production logs in real time, achieving 96% classification accuracy across 5+ log severity levels. That work directly improved security validation practices across the entire engineering organisation.
More recently I've been working with RAG architectures, building retrieval systems using pgvector, OpenAI embeddings, and Spring Boot for SaaS platforms requiring tenant-isolated AI search.
What I build:
Java Spring Boot microservices and REST APIs
Payment processing and FinTech backend systems
Secure, scalable banking architecture
ML model integration and AI-powered backend systems
Event-driven systems with Apache Kafka
Performance-optimized database layers with PostgreSQL
How I work:
Clean, documented, production-ready code from day one
Experienced with Agile/Scrum, sprint planning, and Jira
Regular async updates, no chasing required
Risks flagged early, not after deadlines
I work exclusively with US and European clients. If you need a Java contractor who has built real banking, payment, and AI systems at enterprise scale, let's talk.
