Md. Araful Karim
Senior Software Engineer
Principal systems engineer specializing in high-throughput enterprise backends, distributed PostgreSQL database architectures, row-level locking, and microservices orchestration with Docker and Kubernetes.
RajTech BD Limited is an elite software engineering, enterprise ERP, and AI systems development limited company headquartered in Kuril, Vatara, Dhaka. We specialize in building reliable, custom enterprise platforms that replace cumbersome legacy workflows and eliminate technical debt.

Executive Software Architect & Managing Director
Under the executive direction of Md. Faisal Amir Mostafa, RajTech BD Limited was founded in 2018 with a singular engineering philosophy: modern organizations deserve software tailored precisely to their operational mechanics, rather than generic software that enforces rigid limitations.
"Real digital transformation isn't about slapping generic themes together. It demands atomic accuracy in the database, sub-second latency on every device, and transparent human collaboration between architects and clients from sprint zero."
With over a decade of systems architecture mastery, Faisal has led our engineering laboratory in Dhaka to architect mission-critical ERP engines, multi-warehouse automated logistics suites, and high-concurrency headless digital platforms for enterprises across Bangladesh and overseas.
Each key employee leads a critical division of our engineering practice—from senior backend infrastructure and AI models to agile project delivery and frontend craft.

Software Engineer L2
Full-stack software engineer delivering robust web architectures, scalable RESTful & GraphQL APIs, real-time WebSocket communication, and responsive modern applications with Next.js, React, and Python backends.

HR & Project Manager
Agile scrum leader and human operations facilitator. Manages bi-weekly client sprint reviews, team velocity metrics, developer resource allocation, and continuous enterprise SLA adherence across all projects.

UI Specialist & Frontend Developer
Front-end craftsperson and design system architect. Translates complex enterprise workflows into intuitive, responsive UI components with clean Tailwind CSS, React, and strict Core Web Vitals optimization.

Data Science & AI Engineer
Machine learning researcher and data specialist architecting autonomous agent workflows, retrieval-augmented generation (RAG) knowledge pipelines, computer vision systems, and predictive demand analytics.
Our key engineers combine strict architectural rigor with cutting-edge tools. Every commit undergoes automated linting, security scanning, and senior code review before touching client production environments.

In addition to our core leadership, RajTech BD Limited proudly operates a structured 20+ member workforce comprising our Engineer Level 1 (Associate Engineers) and Engineering Intern Group. Together, they guarantee rapid feature turnaround, rigorous automated regression testing, and 24/7 SLA responsiveness.
Our Associate Engineers handle day-to-day sprint tickets, write tested REST and GraphQL endpoints, craft responsive UI views, and maintain automated CI/CD build scripts. They work under direct daily mentorship of our senior architects.
Hand-selected top graduates and apprentices from prestigious Bangladeshi engineering universities (BUET, DU, IUT, etc.). They focus on automated end-to-end regression testing, unit testing suites, dataset curation for AI models, and performance benchmarks.
Every line of code serves a measurable purpose. We eliminate third-party plugin bloat, excessive JS payloads, and optimize server response times to under 200ms.
Our ERP and inventory engines prevent race conditions, stock discrepancies, and duplicate transactions through robust database locking and isolation.
No convoluted account manager games. You collaborate directly in real-time Slack channels with the senior architects writing your codebase.
We don't optimize for vanity impressions. We engineer technical SEO architectures and sales qualification funnels that generate high-value client acquisitions.
Located in Kuril, Vatara, Dhaka-1229, our engineering facility is equipped with redundant high-speed fiber internet, generator backup power, private cloud servers, and collaborative war rooms designed for continuous sprint delivery.
