About Me

AI/ML Engineer

AI/ML Engineer with around five years of experience building production LLM systems, Generative AI applications, and scalable distributed backend infrastructure. Hands-on across the full stack — RAG pipelines, model fine-tuning, agentic AI, microservices architecture, and cloud-native deployments on AWS. Most recently at Piper Sandler, where I built a LangChain + FAISS retrieval layer over 10K+ SEC filings and earnings transcripts that cut analyst lookup time from ~8 seconds to under 400ms, and shipped a Generative AI portfolio assistant on the OpenAI and Claude APIs. Previously at Dell Technologies, I overhauled the Java Spring Boot + Kubernetes microservices layer behind the OpenManage server platform (1,200 → 8,000 concurrent sessions) and migrated firmware telemetry to Kafka event streaming for 600K+ endpoints; at Airbnb, I shipped Python/Django REST APIs and Redis caching for host availability and messaging. That production work carries into my own projects — Kube-LoRA, a Kubernetes-native LoRA fine-tuning platform; a monitored ChestX-ray14 classification platform with three-layer drift detection; a CLIP + XGBoost learning-to-rank engine; and an autonomous ReAct research agent on LangGraph. Currently completing an MS in Applied Machine Intelligence at Northeastern University in Boston.

My Experience

AI/ML Engineer

Piper Sandler | Boston, MA, USA | Jun 2025 – Nov 2025

  • Worked on a RAG-based document search tool using LangChain and FAISS over 10K+ SEC filings and earnings transcripts, cutting analyst lookup time from around 8 seconds to under 400ms.
  • Contributed to a Generative AI portfolio assistant using the OpenAI API and Claude API, helping the investment team reduce client memo prep time by roughly 6 hours per report.
  • Supported LLM deployment on AWS SageMaker and tracked experiments with MLflow, helping the team move toward a structured MLOps workflow during a period of rapid AI adoption.
  • Assisted in evaluating NLP sentiment classifiers on earnings call transcripts for the equity research pipeline, working in sprint cycles alongside senior ML engineers.
Software Engineer

Dell Technologies | India | Aug 2022 – Aug 2024

  • Partnered with platform engineering and operations stakeholders to scope ambiguous requirements, then overhauled the microservices layer for Dell’s OpenManage server platform using Java Spring Boot and Kubernetes, scaling concurrent session capacity from about 1,200 to 8,000.
  • Built and owned a REST API gateway in Python FastAPI with OAuth 2.0 auth and rate limiting, processing close to 45 million calls per month across 12 data center regions.
  • Migrated a legacy firmware telemetry service to an Apache Kafka event-driven architecture, reducing ingestion latency from 22 seconds to just over 1 second for 600K+ connected endpoints.
  • Automated release workflows using Jenkins and GitHub Actions across 14 backend services, cutting deployment cycles from 3 weeks to about 4 days.
  • Instrumented Prometheus metrics and Grafana dashboards across 8 backend services and translated alert thresholds into business-impact language for non-technical operations managers, reducing mean time to detect production anomalies from about 40 minutes to under 6 minutes.
  • Optimized MySQL query patterns for the server inventory service with Redis write-through caching and query batching, reducing average database read latency from 1.4 seconds to under 180ms across 250K+ asset records.
Software Developer

Airbnb | India | May 2020 – Jul 2022

  • Translated business requirements from product and design into technical specs for host availability and messaging REST API endpoints in Python and Django, shipping through full code review and QA cycles as part of an 8-person engineering team.
  • Reduced PostgreSQL query time on the search results page from about 3 seconds to under 800ms by profiling with EXPLAIN ANALYZE and adding composite indexes.
  • Added Redis caching for high-traffic host listing availability queries, bringing repeat-request latency from 2.1 seconds to under 200ms and cutting database read load by roughly 3,000 queries per minute at peak.
  • Shipped reusable React and JavaScript UI components for the host analytics dashboard, following Figma design specs across browsers and screen sizes.
  • Implemented a bulk-messaging feature with queued Python background tasks, allowing hosts to notify up to 500 guests at once without blocking the main application thread.
  • Wrote unit tests in pytest for new API endpoints and took part in weekly code reviews, helping the team catch regressions before they reached staging.

What I Do

LLM & Generative AI Applications

Build production assistants and copilots on the OpenAI, Claude, and Bedrock APIs — function calling, structured outputs, tiered model routing, and evaluation with LLM-as-judge.

RAG & Semantic Search

Design retrieval pipelines over large document sets with LangChain, FAISS, and vector databases, tuned for sub-second lookup and grounded, citable answers.

Agentic AI Systems

Ship autonomous agents on LangGraph that plan, call tools, and iterate on their own observations, with Pydantic-validated outputs and bounded recursion.

Model Training & Fine-Tuning

Fine-tune and train models with LoRA/QLoRA and PEFT in PyTorch under mixed precision and memory-constrained GPU budgets, from experiment tracking to quality gates.

MLOps & Cloud Deployment

Deploy and monitor models on AWS SageMaker, EKS, and Azure ML with Docker, Kubernetes, Terraform, MLflow, and blue-green canary promotion.

Backend & Distributed Systems

Architect scalable microservices and event-driven platforms with Spring Boot, FastAPI, Kafka, and Redis — built for high throughput and low latency.
