    I have developed more than 10 applications whose total active users are more than 10,00,000. I have more than 9+ years of professional experience in Software Development, especially in Android Development. My main expertise is making customized mobile application design and develop as per client needs. Also, I am experienced in a variety of web and server-related technologies. Recently I've started leading a team of mobile developers. I also have extensive experience in taking on existing, partially-built projects that need rapid rescue, optimization, and preparation for release. Often these projects have been outsourced to a low-cost market, but have struggled to get over the finish line - many of the testimonials you see below are for that type of project.

    Peace be upon you! During the last three years, I have been writing technical documentations which require top level knowledge of technicalities for several government, semi-government and non-government global organizations. I must mention some of them in the following list: ☛ Response to Request for Proposal (RFP) ☛ Project Proposal for both IT and Non-IT Projects ☛ Expression of Interest (EOI) ☛ Terms of Reference (TOR) ☛ Scope of Work (SOW) ☛ Request for Quotation (RFQ) ☛ Software Requirements Specification ☛ Solution Architecture ☛ Feature List ☛ Network & Server Specification ☛ Staffing Schedule I specialize in drawing technical diagrams which are mostly Software Implementation Diagram, Use Cases, UML, Sequence & Activity Diagrams, Flow Charts, Component Diagrams. I hope you have already acquired quite a few reasons to find me as a competitive candidate to serve the technical document you are estimating. And thank you for coming so far. So what are we waiting for? Let's have a discussion and start writing! Regards, Md Mohaiminul Kabir Khan

    I am a Software developer with over 7 years of extensive programming experience in various technologies and frameworks such as Native Android (Java and Kotlin), Spring, Hibernate, and J2EE JSP. From the beginning of my undergraduate degree, I have been working with a few startups to develop a business solution. From there I became much more interested in Business Solutions and Engineering Solutions Making Libraries and Solving challenging problems. Skills • Led the migration of Spring Boot Application from version 2.2 to 3.3, resulting in optimized performance, enhanced API integrations, improved security protocols, and better integration with Docker, Kubernetes, and Istio. • Leveraged Spring Boot to develop an end-to-end e-commerce platform, implementing RESTful APIs, secure payment gateways, and efficient inventory management. • Revamped the ’Jatra’ app using Android modularization and the Compose UI framework, restructuring the codebase into loosely coupled, self-contained modules. This improved scalability, future-proofed the application, and enhanced the user experience, while simplifying the design and management of large systems as they grow over time. • Integrated in-app calling feature for Obhai ride-sharing application, optimized codebase by removing duplicates, and refactored code following SOLID design principles, improving maintainability and scalability. • Develop applications to help oversee the merchandising operations for bKash, the biggest Mobile Financial Service company in Bangladesh, catering to over 4000 end users. • These applications helped bKash boost productivity by a whopping 74%! • We were able to reduce the cost of the Firebase service by 48% by simply updating the database backup policy and cleaning incoming data once all dependent operations have been completed. • Performing Android clean-up tasks in the background threads to remove unnecessary cached data. This helps ensure that users enjoy a smooth experience without encountering lagging or freezing problems. • Boost productivity and streamline tasks by organizing features into modules. • Upgraded dependency injection library dagger 2.2 to Hilt. • Verification of incoming data for accuracy and potential recovery is conducted. In cases where the on-device machine learning model fails to execute the task effectively, a data validation service operates in the cloud. • Reduced code redundancy by 90%! • Building user-friendly UI with jetpack compose. • Developed 100% Dynamic UI that can tweak features from the backend and provides control over features. Working Particulars: Java, Kotlin, Javascript, Python, XML, Jetpack Compose, Bootstrap-5, HTML, CSS, Gradle, Maven, JSON, Agile SDLC, and Git. DBMS: Relational - Oracle, PL/SQL, MS SQL, and BigQuery. Non-Relational - Firebase Realtime Database, Firebase Cloud Firestore, MongoDB, Amazon DynamoDB, Azure Cosmos DB. Experiences with all stages of the Android development particulars and process: - Knowledge of popular libraries like Retrofit 2, Dagger 2, RxJava, Glide, Room, ButterKnife, Stetho, Moshi, and Chuck. - Good to have written tests using various libraries e.g. jUnit, Robolectric, Mockito, etc. - Developing applications using MVVM, MVC, and MVP design patterns. - Android architect component Library. - Modularization development. - Make custom views more accessible. - Strong working experience In Firebase ML, and Cloud Function. - Security with data, Security with HTTPS and SSL, and Network Security Configuration. - Manage App's Memory, and Verifying App Behavior on the Android Runtime (ART). - Testing app component integrations and Testing UI Performance. - Working experience in using GIT and in CI/CD tools such as Jenkins. Experiences with all stages of Spring Boot Microservices development particulars and process: - Professional experience building Enterprise applications using Spring Framework. - In Spring Boot development, mastery lies in understanding both the framework’s strengths and limitations to build efficient, scalable applications. - With four years in Spring Boot, I’ve learned that true backend proficiency is measured by code that is robust, maintainable, and capable of adapting to change. - Backend development isn’t just about coding—it's about designing systems that are both resilient and scalable. Spring Boot makes this achievable, but experience makes it reliable. - developing technical designs, developing, testing, debugging, writing automated tests, delivering and maintaining highly scalable and distributed applications using Java & J2EE, Messaging - JMS, Apache Kafka, and adopting cloud technologies. I like to develop secure, highly scalable, big data, and ML-enabled applications.
