Job Experience
I am a Software Engineer and AI Engineer with experience shipping production ML systems, enterprise applications, and secure infrastructure. My work spans the full stack — from architecting hybrid AI pipelines to engineering mission-critical government systems.
ALTRI.AI
AI Engineer | October 2025 – Present | Remote, US
Building production AI systems for real estate investment analysis, combining modern LLMs with traditional ML to deliver actionable insights at scale.
Key Impact: Achieved a 10× throughput increase by refactoring data enrichment pipelines with async orchestration, significantly reducing cloud compute costs.
Core Contributions
- Hybrid AI Scoring Engine: Architected an engine combining LLM-based feature extraction from unstructured property descriptions with XGBoost models for price prediction and investment recommendations.
- Fault-Tolerant Ingestion: Built a resilient data ingestion engine using HomeHarvest and PostgreSQL, implementing a “Delta Sync” strategy with immutable event logging to track property lifecycles without data loss.
- Model Validation Pipeline: Established a containerized training pipeline with Human-in-the-Loop validation gates, ensuring new “Challenger” models consistently outperform production “Champions” before deployment.
- Full-Stack Development: Developed a FastAPI backend and React frontend backed by Supabase, implementing Row Level Security (RLS) and distributed job locking for safe, multi-tenant concurrency.
- Infrastructure & DevOps: Dockerized the complete microservices stack (API, Scheduler, Trainer) for reproducible deployments across local environments and Render cloud infrastructure.
DYNAMIC SOLUTION INNOVATORS
Software Engineer | April 2023 – Present | Dhaka, Bangladesh
Core member of the engineering team, designing and building mission-critical enterprise systems for major government and public sector clients. Focus on backend architecture, security, and operational excellence.
Key Impact: Slashed redeployment latency by 96% (2m → 5s) by resolving a critical GlassFish hot-swap failure, accelerating team-wide development speed.
Core Contributions
- Engineered secure and scalable Java EE applications for critical government infrastructures (NBR, MoCAT, BCIC), transforming complex bureaucratic processes into streamlined digital workflows.
- Acted as a key member of the internal cybersecurity team, conducting vulnerability assessments, threat modeling, and security audits across projects.
Key Projects
E-Appeal: Digital Appeals System for NBR & USAID
A digital platform for managing tax-related appeals.
- Pioneered the company’s first enterprise-scale JSF application, establishing engineering guidelines and architectural best practices adopted by subsequent projects.
- Designed a multi-layer architecture (View, Service, Repository) with strict separation of concerns.
- Implemented centralized RBAC using Jakarta Security with custom form-based authentication.
- Integrated Java Message Service (JMS) for asynchronous, decoupled event handling (email/SMS notifications).
Project Scratch: Internal Core Services Platform
An internal platform designed to accelerate development by providing reusable core services.
- Engineered a centralized observability stack using Prometheus, Loki, and Grafana — exposing JMX metrics from GlassFish for real-time monitoring.
- Dockerized the complete application stack (GlassFish, PostgreSQL, MinIO, RabbitMQ).
- Contributed a feature enhancement to PrimeFaces open-source (PR #12865).
SHMS: Smart Hotel Management System
A nationwide licensing and registration system for hotels and restaurants.
- Designed a generic, state-driven approval workflow engine, making the logic reusable across multiple application types.
- Utilized Aspect-Oriented Programming (AOP) to cleanly separate cross-cutting concerns like notifications and auditing from core business logic.
BCIC-ERP: End-to-End Enterprise Resource Planning
A comprehensive ERP system for process automation across 12 integrated modules.
- Assumed full ownership of the Procurement and Inventory modules, leading the entire lifecycle from business analysis (As-Is/To-Be modeling) and database schema design to hands-on development and client delivery.
