Dhaka, Bangladesh
I architect and build scalable backend systems that bridge the gap between robust enterprise applications and cutting-edge AI. Currently at Therap (BD) Ltd., I focus on AI-native architecture, system optimization, and production-grade reliability. I specialize in designing context-aware AI workflows, LLM-powered data assistants, and high-speed data pipelines using Java, Spring Boot, ClickHouse, and LangGraph. My recent work includes implementing custom context-fetching protocols via MCP to accelerate developer productivity, and designing zero-leakage SQL security layers for multi-tenant architectures. Beyond my day-to-day enterprise work, I am deeply invested in context engineering and agentic workflows. I actively build tooling that centralizes instructions and contextual memory for AI assistants into project-specific directories, and I enjoy exploring multi-agent system designs. My foundational problem-solving mindset, shaped by competitive programming (ACM ICPC, Google Code Jam) and early work in algorithmic simulations, drives my approach to complex system architecture today. I am passionate about knowledge sharing, actively mentoring developers and conducting technical workshops with organizations like BdOSN and the U.S. Embassy Dhaka. Whether it is modernizing a legacy monolith or building an intelligent, multi-agent platform from the ground up, I love solving hard engineering problems. If you are building systems that need to scale intelligently, let’s connect. Sharing thoughts at: blog.niazbinsiraj.com and niazbinsiraj.com
- Architected and built an AI-powered Data Assistant (Java 21/Spring Boot, React/TypeScript, ClickHouse, Oracle) enabling healthcare billing staff to query millions of claims via natural language; designed a chunked ETL pipeline with SPI connectors streaming Oracle data into ClickHouse on virtual threads, implemented CTE-based multi-tenant isolation with zero data leakage, built a SQL security layer (JSQLParser validation + parameterized CTE wrapping), and integrated an LLM with reflection-driven schema context and report-scoped prompt enrichment, delivering sub-second analytics. - Architected and implemented a full-stack, LLM-powered code documentation system using (Python/FastAPI, React, Oracle 26ai, Gemini) that auto-generates wiki articles at entity, file, section, and repository levels with incremental change detection, thread-parallel execution, crash-safe cleanup, and a Google-Code-Wiki-inspired browser UI with Mermaid diagram rendering and ScrollSpy navigation. - Engineered a context-aware AI development workflow for a large-scale legacy monolith, implementing custom context-fetching protocols using MCP connected to the code-wiki that reduced development time by 40% and accelerated feature delivery. - Built AI-powered analytics dashboard (ag-analytics) that tracks LLM token consumption, cost estimation, and multi-model usage patterns across a web dashboard with Gemini-driven efficiency insights. - Built a Spec Driven Development toolkit (sdd-kit) that enforces a structured idea → specify → implement → review → commit workflow with auto-generated agent skills, reusable workflow definitions, and per-feature traceability, accelerating team adoption of AI-assisted development practices while providing full visibility into AI spending and coding efficiency. - Implemented scalable and future proof full billing workflow of SMI (Serious Mental Illness) services for Nebraska state of America.
- Developed robust web APIs tailored to client and internal requirements using the Java Spring MVC framework. - Designed and optimized database schemas and queries on Oracle databases, utilizing MyBatis and Java Persistence API (JPA). - Implemented advanced archive and search functionality using Therap's internal frameworks. - Designed and developed a complete Excel upload/download solution by leveraging Therap’s internal search and Excel frameworks. - Implemented several scheduled jobs using Cron expressions. - Contributed to the core billing workflow at Therap, ensuring smooth and reliable billing processes. - Researched, designed, and developed the Aging Report system from scratch, incorporating Excel download functionality, using Java, Spring, JSP, and MyBatis. - Gained hands-on experience with EDI X12 file types, including 837, 835, and 999 transactions. - Developed database migration scripts. - Performed thorough code reviews, providing constructive feedback to ensure code quality and adherence to best practices. - Wrote comprehensive unit tests for numerous features, ensuring code reliability and adherence to high-quality standards.
- Successfully completed a 3-month intensive training program in Java EE, Spring, Hibernate, and coding best practices. - Developed and presented a comprehensive Library Management System project, demonstrating a deep understanding of the training concepts. - Gained knowledge of HIPAA regulations and proficiently handled PHI (Protected Health Information) in compliance with industry standards. - Refactored legacy codebases by applying modern Java 8 features such as Enums and Streams, alongside principles like SOLID, DRY, and KISS, enhancing code maintainability. - Designed and developed user-friendly, responsive client interfaces using Java Server Pages (JSP) to improve user interaction and system accessibility. - Conducted thorough code reviews, ensuring adherence to clean coding standards and the strategic use of design patterns for efficient, scalable solutions. - Collaborated with project managers, team leads, and senior developers in technical discussions to drive innovative and feasible solutions.
I did freelancing as a Unity Game Developer in Upwork and Freelancer with the successful completion of three projects. It was an experiment and it went pretty well. - Cloned a 3D hypercasual game for android device using C#, and Unity Game Engine. - Developed squishy cheeks behavior for a 2D sprite using C# in the Unity Game Engine. - Developed shortest path visualizer using A* search and Line Renderer in Unity Game Engine.
