    • Identified that a narrowing-scope product no longer justified its web app and database, led its retirement to lightweight GCS JSON storage, and drove the team’s shift from Git Flow to trunk-based CI to match the faster pace it unlocked.
    • Owned on-call triage across a 100+ DAG portfolio — monitoring SLA dashboards and Slack alerts, root-causing failures via log inspection, and driving business-critical pipelines to 100% uptime; migrated 2 legacy Kubernetes cron jobs to Airflow for better visibility and control.
    • Authored and maintained 20+ of the team’s 100+ production Airflow DAGs (Cloud Composer), from simple linear ETL chains to complex branching pipelines with custom retry, scheduling, and SLA logic.
    • Built extraction pipelines pulling data from REST APIs, FTP servers, cloud storage buckets, and websites (via BeautifulSoup), with separate processing pipelines that cleaned, aggregated, and interpolated data before writing it to the internal database through a writer API.
    • Took on informal tech-lead responsibilities: facilitated scrum ceremonies and backlog refinement, unblocked teammates on technical and domain issues, and onboarded new members through architecture walkthroughs and reviewed documentation.

    • Co-led end-to-end design and development of a full-stack recruitment platform as one of two engineers, owning the frontend, backend APIs, CI/CD, containerization, and cloud deployment.
    • Evaluated ECS Fargate against EC2 and EKS for a multi-service architecture (web app, job matching, job recommendation); chose Fargate to avoid EKS’s operational overhead while still getting managed scaling and failover for a small team.
    • Built the candidate-facing PDF resume generator and the job recommendation module, matching candidate profiles against curated postings indexed in Apache Solr and surfaced via a homepage API.
    • Integrated dual payment rails (VIPPS mobile payment and Stripe) to support both Norwegian mobile-first and international card-based customers, handling one-time and recurring subscription billing.

“Throughout the project's phases, his systematic approach shone through”

As the UX designer during the development of our recruitment portal, I had the pleasure of collaborating with Tushar. Throughout the project's phases, his systematic approach shone through, establishing him as a steadfast member of our technical ensemble. Tushar's adeptness in backend systems, paired with his diligence in refining our Jira workflow, was instrumental in ensuring our project's orderly progression. Although the crux of our collaboration was on design and development, Tushar's proactive endeavor to grasp the nuances of UX played a pivotal role in bridging the gap between design blueprints and their practical execution. Beyond his evident technical proficiency, our work environment was uplifted by Tushar's collaborative spirit, we shared a lot of good laughs! Reflecting on our partnership, I can confidently endorse Tushar for development roles, recognizing his potential to integrate seamlessly into and enrich any team.

“Tushar emerged as a linchpin of technical and organizational expertise.”

In our journey of building a sophisticated recruitment portal, Tushar emerged as a linchpin of technical and organizational expertise. Partnering with Sifat in a remote team based in Bangladesh, Tushar contributed significantly over two years to create a portal that empowers both job seekers and employers. While Tushar's notable work on our Jira setup and CI/CD processes reflects his analytical acumen, it is essential to recognize his broader contributions. His role in the development of the portal, enabling users to seamlessly access job postings, integrate with APIs and a SolR based semantic search for tailored recommendations, and engage in an intuitive application process, was instrumental. Furthermore, Tushar's contributions ensured that employers could effortlessly create job postings, utilize application links, and evaluate applicant compatibility through psychometry. Tushar's dedication, technical know-how, and ability to collaborate effectively with international counterparts, including myself and our UX designer, are testament to his professional caliber. I confidently endorse him for any development or system management roles, certain that his proficiency and commitment will shine through.

“He is a highly capable scrum master and highly skilled Python developer and will make a key contribution wherever he goes.”

Tushar was a key contributor to Ferdia through his dedication to the job, setting a good example to his teammates of good coding practices and cooperation. He is a highly capable scrum master and highly skilled Python developer and will make a key contribution wherever he goes. It was a pleasure working with you, Tushar!

“He knows how to bring the best out of each person and is an outstanding mentor.”

Abdullah was a great professional to work with. We worked together at Brain Station-23 LTD and he helped me a lot to get started and also to understand internal processes. He knows how to bring the best out of each person and is an outstanding mentor. His work ethics is immaculate and problem solving skill is too good. No matter how hard situations we faced, he never became nervous and that makes him a great programmer.
