Karachi, Pakistan - 10:21 pm local time
With 14+ years of experience as a Software Engineer and Architect, I design and deliver secure, scalable, enterprise-grade systems, from greenfield APIs to complex legacy modernisations on time and built to last.
I've worked across payment platforms, banking integrations, e-commerce backends, and AI-powered systems, so I understand what it takes to build software that handles real-world complexity. Whether you're starting from scratch or untangling a legacy SOA system into modern microservices, I've done it before.
⚙️ What I deliver:
— Java (8/17/21) & Spring Boot backends: REST APIs, microservices, event-driven systems
— Full-stack applications with React, Next.js, TypeScript, Node.js / Express
— AI-powered automation using n8n, Spring AI, Ollama, and GitHub Copilot workflows
— Apache Kafka / Avro pipelines, IBM-MQ, RabbitMQ for high-throughput messaging
— Enterprise integrations: Kong API Gateway, Oracle Service Bus, IBM WebSphere, SOA composites
— Cloud deployments on Azure, IBM Cloud, OpenShift, Docker, and Kubernetes
— Payment & fintech systems: ISO 8583, card tokenisation, wallet platforms, banking APIs
— Database architecture: PostgreSQL, Oracle, MySQL, MongoDB, Redis, DB2, CouchDB
— Legacy modernisation: SOA → microservices, IBM WebSphere Commerce, WebLogic, JBoss, Tomcat
— Full delivery pipeline: CI/CD, Git, GitLab, Bitbucket, ELK, Kibana
🧪 Every delivery is backed by JUnit, Mockito, and Cucumber BDD, so you're not just getting speed, you're getting confidence.
I use AI tools daily (Claude AI, GitHub Copilot, Ollama), not to replace engineering judgment, but to move faster without cutting corners.
If you need a senior engineer who can own the architecture, lead the build, and deliver a production-ready system, then let's talk.

Steps for completing your project
After purchasing the project, send requirements so Anand can start the project.
Delivery time starts when Anand receives requirements from you.
Anand works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & requirements review
I review your answers, ask any clarifying questions, confirm the full scope, and agree on the final deliverables list before a single line of code is written.
Architecture & API design
I design the system architecture, database schema, and OpenAPI / Swagger contract. You review and approve before development starts, so no surprises mid-build.
