Software Engineer @ LabOps | Backend Architecture & Generative AI Specialist

I'm a passionate Software Engineer specializing in scalable backend systems and Generative AI integration. Currently building high-performance microservices and deploying LLMs at scale at LabOps, Kolkata. I thrive in dynamic environments, tackling complex challenges and delivering robust solutions.

• 🔭 Currently Working On: Deploying LLMs (Qwen, BERT, ViT) on GCP with GPU acceleration, building ranking/recommendation engines
• 🛠️ Core Expertise: Backend Architecture, RESTful APIs, Microservices, GenAI (LLMs, BERT, Transformers), Cloud Infrastructure
• 🎓 Education: B.Tech in Computer Science (7.98 GPA) with proficiency in Information Security - JUIT
• 🌱 Always Learning: Advanced ML pipelines, system design patterns, cloud-native architectures
• 🏆 Achievements: IIT Mandi Catalyst Incubation | HP CM Startup Scheme | Xartup Fellowship ($5K AWS Credits)

• Deployed Qwen LLM on GCP using Kubernetes and Cloud Run with GPU-enabled endpoints, implementing auto-scaling to support thousands of concurrent sessions
• Designed and implemented robust RESTful APIs for ranking and recommendation engines, streaming user chat logs into BigQuery and exposing personalized results via FastAPI
• Optimized API performance by introducing PostgreSQL indexing strategies, Redis caching layers, and SQL query refactoring - achieving substantial latency reductions and high-throughput for customer-facing services
• Fine-tuned and deployed various ML models (BioClinical BERT, Qwen3-4B, ViT) on GCP with GPU acceleration, creating custom training pipelines and optimizing tokenization
• Engineered mobile app backend features, including a multi-tenant RBAC hierarchy using Django REST and Row-Level Security with dynamic authorization policies
• Enhanced system resilience by diagnosing production-critical defects across Dockerized microservices and implementing centralized alerting with Alertmanager
• Implemented Chain of Thought prompting by structuring intermediate reasoning steps, directly enhancing model interpretability

• Developed scalable backend features using Django REST Framework, including user management, role-based access control, and document collaboration workflows
• Optimized database performance by profiling and refactoring slow SQL queries in PostgreSQL, resulting in significantly faster API response times
• Integrated Redis caching for read-heavy endpoints, implementing invalidation logic to reduce database load and improve application responsiveness
• Collaborated with DevOps team to diagnose and resolve Docker container networking bugs, ensuring stable deployment environments

Tech Stack: Python, Django, AWS, Visual Cryptography Algorithms

• Developed a secure online voting prototype leveraging visual cryptography algorithms to split vote data into visual shares
• Ensured data confidentiality and prevented unauthorized access through cryptographic techniques
• Successfully created a prototype mechanism for secure voting with enhanced security measures

🎯 Recognition & Incubation:

• ✅ Incubated under IIT Mandi Catalyst Program
• ✅ Incubated under HP CM Startup Scheme (State Government of Himachal Pradesh)
• ✅ Xartup Fellowship - Awarded $5,000 worth of AWS credits
