Case Studies

Detailed breakdowns of how I approached real problems.

01

Intelidoc-AI — Clinical Documentation Platform

Software Engineer · OneLab Ventures (Client: Middletown Medical, USA)

Problem

Doctors relied heavily on manual transcription for clinical documentation, leading to time-consuming workflows, delayed EMR updates, and increased cognitive load. Existing solutions lacked accuracy, real-time capabilities, and required significant user training.

Approach

Built a web application and Chrome extension enabling real-time clinical documentation through voice-to-text transcription and LLM-powered summarization. Integrated Deepgram for high-accuracy speech recognition and BastionGPT for generating structured, EMR-ready summaries. Designed a minimalist UX to ensure near-zero learning curve for medical professionals.

Outcome

Reduced manual transcription effort by 60% and achieved 95%+ transcription accuracy. Enabled 3x faster EMR updates and improved clinical workflow efficiency. The intuitive design drove a 40% increase in doctor adoption during early rollout.

HealthVault — Decentralized Medical Records

Personal Project · Blockchain

Problem

Medical records scattered across hospitals and clinics. Patients had no single source of truth for their health data.

Approach

Designed a dApp with Ethereum smart contracts for immutable record storage. Built a clean UI for patients and doctors to access records.

Outcome

Functional prototype with role-based access, record creation, and blockchain verification. Demonstrated at university showcase.

Machli — Fisheries Intelligence Platform

Software Engineer · OneLab Ventures (Client: Reliance Foundation)

Problem

Coastal fishermen relied on outdated systems with no real-time safety alerts, limited language support, and complex UI, making critical information around fishing zones and sea distress difficult to access.

Approach

Revamped a legacy mobile application into a modern, scalable system. Integrated INCOIS APIs for real-time, location-based sea safety alerts and built a multilingual, minimalist UI with text-to-speech support to ensure accessibility across diverse literacy levels.

Outcome

Achieved 10,000+ downloads and 2,000+ daily active users. Delivered 90%+ uptime with accurate real-time alerts, reduced support tickets by 80%, and significantly improved user adoption and retention in rural regions.

WAVE — Workflow Automation & Analytics Platform

Software Engineer · OneLab Ventures (Client: Doctor Alliance, USA)

Problem

Lack of visibility across internal workflows led to delays, manual handoffs, and inefficient service delivery. Systems were fragmented with no real-time tracking or structured UX.

Approach

Built a workflow automation and analytics platform with real-time dashboards to track tasks, teams, and resources. Designed a scalable architecture and implemented cron-based automation for continuous data syncing and reduced manual effort.

Outcome

Reduced turnaround time by 32% and improved operational efficiency by 40%. Decreased manual handoffs by 25% while achieving 100% visibility into real-time workflows and system status.
