Tejas Mahajan is a software engineer specializing in large-scale data systems and the infrastructure that runs them, with a focus on production-grade data platforms and real-time backends for compute-heavy, latency-sensitive domains. Currently at Nimble, I work on the data platform of an autonomous warehouse robotics platform: engineering data pipelines, cost-aware compute layers, and real-time streaming services that turn raw fleet, fulfillment, and robot telemetry into the operator-facing surfaces that run the warehouse floor. Previously at MerQube, I architected the equity and options data ingestion systems and unified data access layers powering complex index computation workflows. My background spans distributed systems, cloud-native infrastructure, and end-to-end ML deployment, from research-grade training and fine tuning deep learning models to deploying in resource constrained production systems. I'm particularly interested in building intelligent, reliable systems at the intersection of data infrastructure, robotics, and autonomous decision-making.

Experience
March 2026 - Present
- Re-engineered a legacy BizOps warehouse-operations dashboard into a documented, stakeholder-aligned, and performant medallion pipelined datasets, codifying ad-hoc metric definitions into parity-validated bronze/silver/gold pipelines and cutting monthly compute spend roughly 10x.
- Architected the real-time data plane behind the live warehouse-operations control surface, shipping a production Rust streaming backend with typed event contracts, supervised SSE broadcast fan-out, GraphQL data integration, and end-to-end Kubernetes and API deployment wiring.
July 2023 - March 2026
- Engineered the migration of equity reference and end-of-day pricing pipelines to a new provider platform, ensuring uninterrupted data delivery for index calculations with zero downtime.
- Led the development of a scalable options data platform, defining the data model, building ingestion and monitoring systems, and partnering with product, data providers, and financial engineers to resolve complex data integrity challenges. Delivered a unified data access layer that powers multi-asset index development and self-service analytics across teams
- Transformed operations workflow by developing automated validation checks for end-of-day prices and corporate action data across multiple providers. Enhanced data accuracy and consistency with customizable override capabilities.
June 2022 - Aug 2022
- Performed in-depth analysis of a vast flight data corpus to uncover spatial and temporal correlations, successfully identifying likely sources of false positives between airborne and ground-based objects.
- Fine tuned the intruder detection models by strategically integrating hard negative samples, leading to a decrease in false positives while preserving optimal sensitivity.
Data Scientist
Karza Technologies Pvt. Ltd. (Acquired by Perfios Technologies Pvt. Ltd.)Mumbai, India
Sept 2018 - Mar 2020
- Successfully delivered an end to end OCR Pipeline for the KYC Documents by implementing a robust synthetic data generation pipeline, model validation, hypothesis testing and training modules for text recognition, card detection and text detection tasks.
- Developed a light weight reformulation of fixed length text recognition model using the CTC framework by progressively optimizing the model towards bridging the latency vs task specific evaluation metric trade-off.
- Engineered the first deployment of deep learning models across AWS Lambda serverless functions and GPU instances, meticulously optimizing for compute, memory, and response time requirements
Aug 2018 - Mar 2019
- Implemented and fine-tuned the Retina-Net object detection network to detect 20 objects comprising garments and footwear. Obtained a mean average precision of 80 on the test dataset.
- Extracted the colour of detected object using image processing functions and mapped the colour to its appropriate shade name.
- Enhanced the user’s visual experience with detected objects image tags overlaid on the image and the generated metadata used to improve the underlying search algorithms.
