March 2025 - Present

JoinUp is on a mission to make professional events more discoverable and accessible. By connecting attendees with relevant conferences, meetups, workshops, and networking opportunities, JoinUp helps people learn, connect, and grow their careers. For hosts, it's an entire operating system for them.

  • Architected and scaled JoinUp (0→1), a production-grade professional events marketplace, owning end-to-end backend, infrastructure, and deployment across AWS and GCP.
  • Built an SEO-optimised Next.js (App Router) frontend with SSR, dynamic metadata, and sitemap/robots configuration, driving 3,000+ organic users/month, improving website conversion by 8%.
  • Designed a geo-spatial discovery system (Google Maps API + PostgreSQL) delivering low-latency, location-based recommendations to 500+ DAU at sub-500ms p99.
  • Implemented Python-based event crawlers and ETL pipelines with Redis caching, PostgreSQL-powered event matching, and built-in admin dashboard for event managers.

Apr 2025 - May 2026

Built an autonomous LLM-driven trading AI agent that executes fully automated token trades on Hyperliquid, based on the condition set by user such as market trends, community sentiment, recent news, tweets, etc. It can also be used to copy trade of sharks or whales.

  • Architected a fault-tolerant microservices system (Executor/Evaluator/Flusher) using RabbitMQ, enabling horizontal scalability, fault isolation, and zero-downtime processing 50+ real-time market signals per minute.
  • Designed resilient queue-based orchestration with ack/nack semantics, retries, and auto-reconnect mechanisms, reducing system failures in AI-driven decision pipelines.
  • Deployed and managed Kubernetes clusters within Confidential Virtual Machines (CVMs), establishing a zero-trust environment for highly secure AI-sensitive data transfer and processing.

Software Development Engineer

Gist Impact

no. WK-03
Feb 2024 - Apr 2025

Managed and scaled infrastructure for SaaS and DaaS platforms powering AI-assisted sustainability analytics workflows, processing ~5 TB of data per month. Worked on enhancing the existing platform's reliability, scalability, and performance.

  • Re-engineered and optimised CI/CD pipelines using GitHub Actions, parallelising build stages, caching dependencies, and eliminating redundant test runs, cutting deployment time from 30 minutes to 5 minutes (6x improvement).
  • Automated ETL pipelines in Snowflake, reducing data processing time by 80% and significantly improving the reliability and consistency of production data flows.
  • Consolidated service logs into a centralised Grafana Stack observability framework, reducing error resolution time by 35% and increasing deployment velocity by 20%.
  • Streamlined and optimised data ingestion and processing workflows for both SaaS and DaaS platforms, resulting in an 80% reduction in data processing time and a significant improvement in overall system reliability and performance.

Summer Research Intern

Indian Institute of Technology, Indore

no. WK-05
April 2021 - May 2021

Conducted a seismic data analysis for the Hindukush region of 59255 earthquakes over the years 2000-2020. Reckoned the b-value for the target region as 1.136 ± 0.007 using the Gutenberg–Richter relation. Determined which locations are suitable for construction-related operations after carrying out a study based on a non-uniform division of the region.
