tanvir-ux/README.md

Hi, I am Tanvir

12+ years of coding. I have been on GitHub since December 2014. I am a Lead Software Engineer and a hands-on Senior Software Engineer (5+ years professional) working on distributed systems, high-concurrency banking APIs, and production Agentic AI.

Java, Spring Boot, microservices, Kubernetes, Kafka, cloud, RAG/MCP.

Dhaka, Bangladesh · tanvir-ux.github.io · tanviralamshuvo@gmail.com · +8801716416679

Featured: AI engineering, every layer

ai-engineering-stack (live replay) is one working enterprise knowledge copilot that covers the whole stack: React front end, OIDC sign-in and RBAC, FastAPI gateway, LangGraph orchestration with human approval, an OpenAI Agents SDK agent, an MCP tool server, PySpark and Delta, a Databricks bundle, Snowflake SQL and dbt, hybrid retrieval with evals, Docker, Helm, Terraform and CI. The README says plainly what was run and what was only validated.

Related showcases: agent-platform, graphrag-service, llm-finetune-serve.

Open source I merged in 2026

A few patches I got into production this year:

Project What I changed PR
Google Gson Update JSON path after promoteNameToValue #3098
Facebook Infer Fix BufferOverrun false positive on String.split with a non-positive limit #2094
Apache Maven Fix ArtifactCoordinates.getId() double colon when classifier is empty #12813

Netflix DGS Preserve user spring.autoconfigure.exclude lists #2339
Checkstyle Quote UnusedLocalVariable examples #21362, #21363

I also merged keras-team/keras-io#596 a while back.

Some of my work

  1. agentic-mcp-gateway — MCP server + agentic RAG tools (retrieve docs, search payments, create tickets). Runs without an API key.
  2. banking-payments-spring — Spring Boot 3 / Java 17 payments API with JWT, idempotency, Kafka events, ISO 20022-inspired flows. My own demo, not bank IP.
  3. kafka-spring-microservices — Transfer API, double-entry ledger, and notifications over Kafka, with docker-compose and Kubernetes manifests.
