Applied ML Infrastructure — Dhaka, Bangladesh

AI infrastructure for
systemic bottlenecks.

RoosCloset Labs engineers AWS-native intelligence to solve massive, overlooked inefficiencies. We help fashion enterprises reclaim $100B in lost returns, and we are transforming how 170 million Bengali citizens navigate civic life.

The Problem Space

Two massive markets.
Two structural failures.

Fashion e-commerce bleeds revenue because it treats visual catalogs like flat spreadsheets. Meanwhile, millions of citizens face an invisible wall of bureaucracy, lacking a unified digital guide that actually speaks their language. Both are fixable with applied machine learning.

82%

Catalog failure rate

E-commerce search fails because product data is written for warehouses, not for human aesthetics. ATLAS eliminates this at the source.

40%

Average return rate

The fashion industry loses $100B annually to returns. 47% are caused by sizing; 31% by photography mismatch. These aren't random events—they are predictable and preventable.

170M

The Civic Divide

Navigating government processes requires insider knowledge. Bangladesh has 170M citizens who lack a centralized, accessible way to create official documents.

Product 1 — Retail Intelligence
ATLAS

Give your catalog
a human eye.

ATLAS takes a raw product image and breathes life into dead data. It returns 180+ structured attributes, a 512-dimensional style embedding, and consumer-ready copy—in under 60 seconds.

Merchant product data is built for inventory systems, but customers shop with aesthetic intent. ATLAS bridges this gap by looking at a garment and instantly extracting its semantic DNA—translating pixels into a language your search engine actually understands.

The result is transformative: Search that finds what customers mean, not just what they typed. Recommendations that grasp personal style. And critical return risk flags raised before a product ever goes live on your site.

Product 2 — Return Intelligence
MIRROR

Stop predicting returns.
Start preventing them.

The fashion industry is drowning in dashboards that offer no real solutions. MIRROR changes the paradigm using causal AI. We score every checkout in 150ms and isolate the exact reason a return will happen.

Prediction without causal explanation is useless. MIRROR is built on DoWhy causal inference—the same framework used in advanced academic research—trained directly on your returns data to identify true causal roots versus mere correlations.

When MIRROR tells your merchandising team that adding a specific size chart will reduce returns by 12%, it is providing a backdoor-adjusted causal estimate. It prescribes ranked interventions with measurable ROI, transforming insight into immediate action.

Product 3 — Civic Technology

Transforming how
Bangladesh navigates life.

Navigating bureaucracy shouldn't require insider knowledge. BoroBhai is a centralized, AI-powered civic hub that democratizes access to state services for 170 million citizens.

Official forms generated

BoroBhai is the single destination to get answers and take action. Ask a question in everyday Bengali or Banglish, and it instantly retrieves the correct workflow from a rigorously reviewed civic knowledge base. But it doesn't stop at advice—it actively creates the government forms, trade licenses, and legal agreements you need to move forward.

By shifting the burden of bureaucracy from the citizen to the machine, BoroBhai ensures no one is left behind by the digital divide. It is enterprise-grade infrastructure deployed for public good.

Bengali NLP

Expert Comprehension

Speak naturally. BoroBhai natively understands formal Bengali, conversational slang, and mixed-script Banglish.

Document Generation

Instant Form Creation

Stop hunting for templates. Instantly generate perfectly formatted trade licenses, leave applications, and agreements.

Voice Input

Accessibility First

Built for everyone. High-accuracy Bengali speech recognition allows citizens to navigate using only their voice.

File Tools

The Central Hub

Merge, compress, and convert your official PDFs directly within the chat window to meet government portal requirements.

Infrastructure

Engineered for the enterprise reality.

We don't build API wrappers. RoosCloset Labs engineers 100% AWS-native infrastructure deployed via CDK. Our platforms feature zero-trust multi-tenant isolation, real-time event streaming, and automated continuous retraining pipelines out of the box.

Multi-tenant isolation isn't a convention; it is cryptographically enforced. We utilize tenant-prefixed S3 paths, partition-keyed DynamoDB architectures, per-tenant OpenSearch indices, and Cognito with custom identity claims to ensure absolute data sovereignty for every client.

Operational Leadership
Najmun Nahar Khan
Founder & Lead ML Architect

A track record of engineering mathematically rigorous, production-grade AI systems. Rather than building theoretical models, Najmun specializes in dismantling complex industry bottlenecks and reconstructing them into scalable, cost-optimized AWS infrastructure.

Previous deployments include physics-informed SegFormer architectures for flood detection, Gaussian Process Regression for epidemiological forecasting (9.8% MAPE), and SMS-based agricultural advisory systems scaling to rural populations at $0.001 per inference. Every system is in production. None are demos.
