Eunusur Rahaman

Senior Software Engineer L1 — Full‑time, Onsite · Jan 2026 – Present

Leading architecture evolution and technical direction across enterprise SaaS systems including ERP, CRM, Inventory, and Hotel Management. Contributing to engineering leadership through architecture decisions, onboarding, mentoring, and hiring support as the company scales.

Designed a reusable UI theming system across Angular and Blazor applications, enabling consistent UI switching across SaaS products and establishing a standardized internal UI foundation.

Collaborated with international stakeholders across Europe, Africa, the Middle East, Australia, and USA for requirement analysis, demos, and solution planning. Participated in AI-assisted agentic development workflow workshops to improve engineering productivity.

Software Engineer L3 — May 2025 – Jan 2026

Owned development of core modules across multiple enterprise SaaS platforms with a focus on modular architecture and scalable business workflows.

Played a key role in a Hotel Management System for a Saudi-based client — built booking workflows, payment integration, and custom recurring billing features from the ground up.

Led core module development for a Hospital Management System for a Greece-based client built as a modular monolith using ABP Framework. Collaborated closely with a senior international engineer and gained strong exposure to production-grade architecture and long-term maintainability practices.

Software Engineer — Mar 2024 – May 2025

Worked across multiple enterprise SaaS systems focusing on backend engineering, system modernization, and cross-platform UI experimentation.

Introduced and evaluated Blazor and Blazor Hybrid development internally, exploring cross-platform solutions for web and Windows. Contributed to a large-scale US-based geotechnical enterprise system on MVC architecture — built backend workflows, PDF reporting (PdfSharp), and system modernization improvements.

Developed an Adobe Photoshop extension integrated with the internal task management system for workflow-based time tracking.

Software Engineer — Sep 2024 – Nov 2024 · US Client

Joined a US client's greenfield project as one of the founding engineers on a 17-service enterprise SaaS platform covering CRM, Sales, Inventory, Finance, Payments (Stripe), and more. Researched and owned the core ABP microservice architecture — YARP API gateway, schema-per-service PostgreSQL, RabbitMQ event bus, and centralized OpenIddict authentication across all services.

Taught the team how to leverage ABP's built-in capabilities — distributed event bus, DDD layers, module system, and multi-tenancy — so developers could focus on business logic rather than infrastructure. Onboarded engineers onto a 117-project solution and established ABP best practices that measurably accelerated feature delivery.

Software Engineer — Sep 2024 – Nov 2024

ABP microservices platform for a US-based client.

Junior Software Engineer — Nov 2023 – Mar 2024

Focused on ABP Framework research, modular architecture design, and early-stage SaaS development. Studied ABP internals — modular structure, configuration system, and UI customization — which improved internal architecture standards and development consistency.

Contributed to the initial design of modular SaaS systems by defining reusable patterns later adopted across multiple projects. Supported modularization of legacy monolithic systems and helped establish standardized Git flow practices across teams.

Built reusable C# and TypeScript components to improve development efficiency and maintainability across enterprise systems.

Software Engineer Intern — Full‑time, Hybrid

Jun – Oct 2023 (5 months). Participated in workshops and training to adopt industry best practices, including Agile (Jira) and unit testing.

Improved coding practices with design patterns; applied OOP and SOLID principles across assignments.

Credentialing Analyst — Remote via Radiant Data Systems (BD)

Reviewed provider licenses and certifications for a leading US healthcare staffing organization; coordinated with clients and vendors to ensure accurate, on‑time credentialing.
