01 / Verto · Production system AI & automation

Onboarding STP Pipeline

A straight-through processing (STP) pipeline that pairs an AI onboarding assistant with native AI workflows to fully automate onboarding for eligible profiles, cutting turnaround from 48 hours to 20 minutes.

The problem

Onboarding required manual coordination and long turnaround times.

My contribution

Built a configurable AI onboarding assistant, followed by a straight-through processing pipeline for eligible profiles. Workflows adapt to country, industry, and administrator preferences.

Deep Research Risk Agent

An autonomous research agent built into the onboarding assistant that screens each applicant against company policies, researching their details across public sources on the internet to surface and flag risk signals, catching risks on 40% of profiles that manual review was missing.

The problem

Applicant risk reviews required extensive manual research across public sources.

My contribution

Built a research agent inside the onboarding assistant to investigate applicants against company policies and surface risk signals for human review. The resume reports risks on 40% of profiles that manual review was missing.

03 / Verto · Production system Backend & real-time

Real-Time Socket Service

A fully serverless WebSocket and pub/sub service that replaced long polling to power real-time features across the product, including web push notifications and a live case-management notification layer.

Inside the project

The problem

Long polling slowed real-time product communication and created infrastructure overhead.

My contribution

Designed a serverless WebSocket service using pub/sub. It powers web push and live case-management notifications; API bottleneck removal and the real-time layer reduced average case-management response time.

Inside the project

The problem

An event platform needed low-latency video meetings and live streaming.

My contribution

Built the video system at Ewently with Python, Golang, WebRTC, RTP, and RTMP. As co-founder, I also led a team of five and owned backend architecture.

The idea

Explore core banking operations through a backend service.

What I built

A Golang API for account creation, user management, and transaction handling, supporting more than 1,000 simulated transactions per day.

06 / Personal project Backend & real-time

Service Management CRM - API

Created a service management CRM using Django and Django REST Framework. It is an API to manage the customer's relationship which purchases any service from a company.

The idea

Keep service purchases and customer relationships organized.

What I built

A service-management API built with Django and Django REST Framework to manage customer relationships for service-based businesses.

07 / Community project Web & community

DSC BVP Website

I developed the website for DSC BVP during my tenure as head of web development, to create events for the members and take RSVP responses from the members to book a suitable venue for the event.

Inside the project

The problem

A developer community needed a simpler way to organize events and capture RSVPs.

What I built

Developed the DSC BVP chapter website, registration portal, and event RSVP system while serving as Head of Web Development.

08 / Technical writing + project Backend & real-time

Manage Login Activity of User

I used the concept of session simulation using jwt to manage the user's login activity, thus keeping the reliability, security, and stateless nature of jwt and thereby perform the intended task to manage the login activity of the user.

Inside the project

The idea

Track login activity while retaining a stateless JWT-based authentication approach.

What I built

Used session simulation with JWT to manage user login activity and wrote a practical guide explaining the approach.

09 / Technical writing + project Backend & real-time

Scalable OTP Service using Node.js

It is an API that implements a OTP service in a scalable manner. In this, we do not need to store OTP with email or phone numbers rather an encrypted object is sent in response when OTP is requested which is decrypted and verified at the time of verification.

Inside the project

The idea

Build a scalable OTP API without storing each OTP alongside an email address or phone number.

What I built

Designed a flow that returns an encrypted object when an OTP is requested and decrypts and verifies it during verification. Documented the approach in a technical article.
