# Iftekhar Munrat > Software Engineer @ LinkedIn | Backend Systems and Infrastructure Location: United States, United States Profile: https://flows.cv/iftekhar I have a Bachelor of Science in Computer Science from the University of California, Davis, and I am currently a System Software Engineer at LinkedIn. My core competencies include Python, Scala, Java, Apache Spark, and data engineering. At LinkedIn, I actively use Python, Scala, SQL and Java for a variety of use cases, from developing CLI tools that interact with databases and API, to maintaining the infrastructure of multiple Samza processors using Java. I am passionate about building scalable and reliable systems that deliver value to both customers and stakeholders. I enjoy working with diverse and collaborative teams, and I am always eager to learn new technologies and best practices! ## Work Experience ### Software Engineer - Systems and Infrastructure @ LinkedIn Jan 2023 – Present | Mountain View, CA - Built an end-to-end Scala Spark pipeline to track workflow reliability across teams, integrating outputs into Retina (in-house dashboarding tool) that surfaced actionable insights, improving org-wide job success rate from 70% to 95% (+25%) by surfacing top failing flows and holding biweekly meetings with flow owners. - Maintained waterloo-lime API, a high-throughput service handling 500K+ QPS serving member data to all internal Linkedin consumers. reduced ERROR/WARNING logs by 50% by fixing critical bugs such as batchGet, A/B testing misconfigurations, table usage, and restored functionality and reliability in the testing environment. - Led the migration of 8 processors from in-house taxonomy storage (Wormhole) to open-source solution (Ambry), designing a reusable repository for taxonomy downloads, version polling, and integration with both Samza (stream processing infrastructure) and Spark workflows. - Currently migrating waterloo-databus-adapter, a stream processor for profile update Kafka messages, from Samza to Apache Flink, rebuilding low-level APIs, implementing custom windowing logic for deduplication, integrating RESTLi-based reprocessing, and validating correctness via parity testing. - Collaborated cross-functionally with multiple teams, triaging client issues (e.g., incorrect data, quota overuse, access errors), leading biweekly reviews, and ensuring system reliability and client trust across critical infrastructure. ### Backend - Systems and Infrastructure @ LinkedIn Jan 2022 – Jan 2022 | Remote - Built a Java based internal command line tool to automate the impact analysis of deprecating a dataset or a field. - Enabled analysis of 1000+ datasets with metadata exceeding 500MB within 5 minutes. - Improved analysis time by 8x over existing manual processes while also reducing human error. - Integrated tool with internal services to retrieve metadata and dependency information about a dataset/field. - Implemented a loosely coupled plug-in architecture to allow integration of 3rd party services. - Utilized CloseableHttpClient, HttpResponse and HttpGet libraries to communicate with API’s. - Authored concise and user-friendly documentation for both clients and developers. ### Software Engineer Intern @ HubSpot Jan 2022 – Jan 2022 | Remote - Utilized ReactJS to work on Custom Behavioral Events(CBE), an app that allows businesses to track user interactions and behaviors from any online page and gain access to interaction insights such as user location, visited page, device type etc. - Navigated and extracted information from API calls and utilized ImmutableJS to manipulate the data and implement the “Timestamp” filter on the CBE page which lets users see the timestamp of when an event occurred. - Utilized useHistory and created a custom hook to persist date filters such as report frequency and date range on the URL so that data is pulled from the URL instead of reverting to default settings. - Implemented tests using the React Testing Library to mimic user interactions via click, scroll and hover events. - Built highly scalable, generalized functions that abstract functionality which resulted in clean, efficient and reusable code and avoided repetition. - Developed and implemented reusable UI components for the event creation flow for CBEs. ### Frontend Technical Manager @ #include @ Davis Jan 2021 – Jan 2022 - Pioneered the development, debugging and redesigning of a website for local non-profit organizations by leading an 8 member frontend team in an Agile environment. - Exercised key concepts of ReactJS, HTML, CSS and Bootstrap5 to make the website visually appealing. - Utilized component-based development and state-management tools like useState, useEffect. - Coordinated effectively with the Design team regularly for a smooth development process. ### Software Engineer Intern - Test Automation @ HCL Technologies Jan 2021 – Jan 2021 | California, United States - Automated end-to-end functional testing of mobile applications using the Jest and Appium frameworks. - Built a library of scalable, low maintenance functions to serve as building blocks for test automation. - Utilized Xcode to emulate iOS devices and tested websites' functionality via the emulators. ### Research Assistant @ University of California, Davis Jan 2021 – Jan 2021 | Davis, California, United States - Worked on supporting an application that analyzes housing data and provides price and rent estimates using machine learning models such as Random Forest and Convolutional Neural Networks. - Maintained a python based web-scraper that extracts 2500 housing data points from Zillow every 3 days. - Implemented cron jobs on Linux to automate script running and data storage on No-SQL MongoDB database. ### Computer Science and Mathematics Tutor @ Los Medanos College Jan 2019 – Jan 2020 | Pittsburg, California, United States - Tutored computer science and mathematics 20 hours per week; approximately 15 students per shift. - Implemented Polya’s Heuristic and the Socratic method to assist students with their programming and math assignments - Collaborated with a minimum of 4 peer tutors to ensure proper assistance to all students while maintaining proper staffing in every study room. ### Computer Science Club President @ Los Medanos College Jan 2020 – Jan 2020 | Pittsburg, California, United States - Led a team of 4 people that worked on an image processing application using openCV in Python. - Held weekly design sessions to discuss features, enhancements and roadblocks. - Initiated a biweekly group LeetCode marathon to develop coding interview skills ### Sales Associate @ Staples Jan 2018 – Jan 2019 | Antioch, California, United States - Showcased excellent customer service to over 100 customers a day by identifying customer needs and providing product recommendations. - Helped Troubleshoot hardware and software issues on customer products such as failed hard-drives, blue screen errors etc. -
