Md Showkat Hossain Chy

Baylor University

M.S. in computer science, Waco, Texas

• Concentration in machine learning for software systems, microservice architecture, and distributed data processing.

Daffodil International University

B.Sc. in computer science and engineering, Dhaka, Bangladesh

Founder and Engineer

Stealth AI startup, Seattle, Washington

• Building an agentic AI platform that monitors municipal records, council agendas, zoning dockets, and permit filings across U.S. cities, and converts them into early business signals for commercial real estate and multi-site operators.

Software Development Engineer, AWS Infrastructure Supply Chain

Amazon Web Services, Seattle, Washington

Product lifecycle management system governing hardware parts and engineering changes across AWS data centres and device manufacturing.

• Modelled millions of hardware components, assemblies, and bills of materials as a graph in Amazon Neptune and DynamoDB, supporting change-impact traversal across products, sites, and programs.
• Held the hardware system of record to a 24-hour data-freshness SLA with an event-driven reconciliation service on EventBridge, SQS, AWS Batch, and DynamoDB that detected and safely replayed dropped, duplicated, and out-of-order updates.
• Built the platform end to end: a Java and Spring Boot rules engine evaluating site, region, and program policy from declarative configuration, through a GraphQL, React, and TypeScript interface. 60% gain in hardware qualification efficiency, with new categories onboarded across 100+ manufacturing sites without per-class code.
• Integrated 15+ cross-region systems against a single source of product data behind versioned Spring Boot REST APIs and events, with role-based access control, fine-grained access control, and per-caller rate limits.
• Raised integration test coverage from 60% to 90% with Cypress, and instrumented the platform with CloudWatch, real user monitoring, CodeGuru profiling, and Lambda-based TLS certificate monitoring.
• Made attributes, classification, and lifecycle rules data-driven, so new hardware categories onboarded across 100+ manufacturing sites with no engineering work and no custom code per product class.
• Established team-wide AI-assisted development workflows using Claude Code and Amazon Q.

Research Associate II, Software Engineering

CloudHubs Lab, University of Arizona, Tucson, Arizona

• Led the lab's graph-learning line: graph neural networks and variational autoencoders with fuzzy c-means clustering over large static-analysis dependency graphs, recovering latent structure automatically. Published at IEEE/ACM ASE 2024 and in Cluster Computing.
• Designed and released a multi-variant benchmark suite giving controlled, reproducible subjects for architecture research.
• Characterised how changes propagate across service boundaries.
• Mentored 15 graduate and undergraduate students in experimental design and empirical evaluation.

Full-Stack Developer, International Collegiate Programming Contest

ICPC Foundation, University of Arizona, Tucson, Arizona

Contest platform for the world’s largest collegiate programming competition.

• Built contest-management workflows in Spring Boot, React, PostgreSQL, and REST covering registration, scheduling, and logistics for 50,000+ students annually across 50+ regions.
• Designed a multi-tenant, configuration-driven platform letting regional managers publish events independently. 45% reduction in administrative time, $12K saved annually.
• Ran static analysis with SonarQube, resolving 1,600+ defects and security issues.
• Covered team registration, contest scheduling, hotel logistics, and event administration, replacing the one-off websites each region had been maintaining.

Software Engineer, Summer Intern

Tyson Foods, Springdale, Arkansas

• Delivered Unreal Engine virtual-reality quality-inspection training for 200+ manufacturing personnel, worth $233K in annual savings.
• Automated 3D asset generation, cutting a two-week manual process to 10 minutes on an AWS EC2 and Perforce pipeline.

Graduate Research and Teaching Assistant, Computer Science

Baylor University, Waco, Texas

• Built distributed MapReduce and PySpark pipelines on Amazon EMR over 10M+ blockchain transactions, extracting opcode and control-flow features from Solidity bytecode and training anomaly-detection models. 65% improvement in analysis efficiency.
• Ran a controlled empirical evaluation of four JVM message queues (Kafka, Artemis, Pulsar, RocketMQ), measuring latency, message ordering, and delivery reliability under concurrency.
• Implemented a transaction manager in Python enforcing ACID guarantees through strict two-phase locking and write-ahead logging, with crash recovery under concurrent workloads.
• Taught software engineering (Java) and C++ programming: 125 students across five sections.

Software Engineer, Wearable Platform

Samsung Research, Dhaka, Bangladesh

Wearable connectivity and firmware for Galaxy Watches, fitness bands, Samsung Health, and the Smart Ring program.

• Developed FreeRTOS firmware and device drivers in C and C++ over SPI, UART, and I2C for heart-rate, stress, and sleep tracking across 90+ exercise modes. Profiled and debugged races and timing defects at the microcontroller level with JTAG and Trace32 under fixed memory and power budgets.
• Designed the Bluetooth Low Energy and GATT control and data planes — service discovery, characteristics, message framing, connection stability — sustaining real-time sensor streaming on a 15 ms cadence.
• Founding engineer on phone-to-wearable connectivity shipped to 2M+ devices with no known production defects. Authored the Samsung Accessory Protocol libraries in C and C++ for Android and iOS.
• Built rollback-safe over-the-air update workflows with recovery paths for devices that could not be physically retrieved: 95% test coverage, 99% rollout success, zero bricked devices.
• Defined the latency and throughput targets the connectivity stack was held to, and worked against a Linux toolchain with emWin on the display side.

Software Engineer

Divine IT Limited, Dhaka, Bangladesh

• Built Django, DRF, and PostgreSQL ERP modules across payroll, HR, inventory, sales, and procurement for 5,000+ daily users, improving throughput by 30%.
