Ishak Islam
Senior Python & Backend Engineer
Category : Web development
Senior Software Engineer with 11+ years of experience building scalable, high-performance backend systems using Python, FastAPI, Laravel, and PHP. I specialize in designing clean architectures, RESTful APIs, and data-driven platforms that support real-world products at scale.
I hold a Master of Computer Applications (MCA) and have worked across multiple domains including SaaS, IoT, aviation, e-commerce, wellness, and enterprise platforms for clients in the US, UK, and Europe.
Over the years, I’ve led and contributed to backend systems involving authentication, role-based access, performance optimization, Redis caching, database tuning, and complex third-party integrations. I’ve also supported IoT platforms, building Python services for device communication and MQTT-based data workflows.
I actively work with AI-assisted development and prompt engineering, using tools like ChatGPT, Claude, and GitHub Copilot to accelerate development and improve code quality. I’ve also built agentic AI solutions, including intelligent chatbot modules using OpenAI models, designed to automate workflows and support user decision-making.
In addition to backend engineering, I’m a data analytics enthusiast, having completed a 6-month hands-on internship, where I worked on real-world datasets using Python, Pandas, NumPy, Tableau, and visualization libraries to generate actionable insights.
I enjoy solving complex problems, mentoring developers, and building systems that are reliable, scalable, and future-ready. I’m always open to opportunities involving Python backend development, FastAPI, AI-driven systems, or product-focused engineering teams.

Designing and developing backend systems primarily using Python, with Laravel-based services, focusing on scalability, performance optimization, and clean architecture. Improved application performance by implementing Redis-based caching strategies and optimizing slow-running database queries.
Key Projects & Contributions -
Designed and implemented email and push notification modules using Laravel 9 for a US-based automotive platform (Young Automotive Group).
Developed and maintained Laravel-based backend services for US-based pest control platforms (Aruza, Anthem), improving system reliability and API responsiveness.
Used Python for data analysis, geocoding, reverse geocoding, Excel-based data processing, and bulk data insertion, supporting large-scale operational datasets.
Developed Routes-Pro, an in-house pest control service management system using Laravel 8.
Built backend services for PupSuite, an IoT-enabled dog house application, using Flask for device data handling.
Developed multiple e-commerce platforms using CodeIgniter 3, supporting catalog management and order workflows.
Backend developer for Aero Lounge, an aircraft rental platform:
Designed RESTful APIs using FastAPI for mobile and web applications.
Implemented an agentic AI chatbot module using OpenAI (GPT-4o-mini) to support user interaction and automation.
Contributed to SPIN (Sports Idol Nation), a sports and wellness coaching platform, building backend services using FastAPI.
Backend developer for NextPro, an IoT smart door lock system, using Python Django with MQTT-based device communication.
