01 — About

Setting technical direction, then making it ship.

I'm a software architect and engineering leader who breaks big monolithic applications into smaller, independent services, shapes how systems talk to each other, and builds in security and scale from the start.

I'm known for setting technical direction, mentoring teams through design and code reviews, and turning complex business needs into simple, maintainable solutions — most recently leading architecture for large airline platforms at Emirates.

Senior Technical Lead — Software Architect track

Coforge · Client: Emirates, Greater Noida

Aug 2022 — Present

Promoted from Technology Specialist

▹Lead architecture and technical direction for large airline platforms (Emirates), guiding system design and a team of 7+ developers and QA engineers.
▹Led the move of a large monolithic booking platform (ResConnect) into smaller, independent services — splitting frontend and backend so each can be built and released on its own.
▹Designed domain-driven, stateful microservices for the Booking and Ancillary domains using Java 17 and Spring Boot.
▹Designed the API gateway and security setup, with one central place to check access tokens so services can talk to each other safely.
▹Used event-based messaging (Kafka & Solace) to pause and resume screen recording while payment details are entered — so sensitive information is never captured. Used Couchbase for fast, distributed data access.
▹Strengthened platform security by fixing vulnerability and penetration-test findings, and mentored engineers through design and code reviews.

Senior Software Engineer

▹Engineered automated content-aggregation crawlers (Selenium) across 200+ sources and data pipelines for ingestion, transformation and delivery.
▹Developed CMS web interfaces with Vue.js and AngularJS; optimized MySQL queries and indexing for high-volume processing.
▹Led a small team, ensuring code quality, system stability and timely delivery.

04 — Featured projects

Systems built to scale, secure & release.

14 projects across three companies plus a personal AI POC — from a multi-year airline microservices program to content automation at news scale, XML-driven publishing automation, and an agentic quote-processing platform. Each with a high-level architecture sketch.

QuoteAssist

Personal project · AI quote-processing platform

An AI platform that ingests travel quote requests from Outlook or web forms, extracts structured data, enforces corporate policies, generates pricing-ready JSON and drafts intelligent email replies — designed to self-improve and graduate trusted patterns to auto-send.

ElixirPhoenix · LiveViewOTPPythonLLM / GenAIRAGReactMS Graph APIPostgreSQL

Core capabilities

Multi-channel ingestion
Outlook Add-in, web forms and webhooks, normalised through one pipeline.
AI extraction + confidence scoring
LLM parses free-form text into structured fields; low-confidence ones flag for human review.
Policy enforcement & smart drafts
RAG-based corporate rules gate the quote; composes a response — or a targeted clarification email for missing fields.
Adaptive learning → auto-send
Agent corrections become training signals; patterns graduate to auto-send, with a kill switch on confidence drop.

Auto-playing request flow…

Feedback loop — agent corrections become labelled training signals that fine-tune the model and raise per-pattern confidence, graduating trusted patterns to auto-send.

Microservices Transformation

Senior Technical Lead / Architect · Coforge

Contributing to the incremental decomposition of a legacy monolith booking system into microservices — scoped across four active modules with hands-on architecture and implementation.

Java 17Spring BootReactREST APIsOracleCouchbaseSOAP → REST

Features & contributions

Ancillary Services — Bags
Designed and implemented UI and backend modules for Bags within the Ancillary Services domain, covering end-to-end feature delivery across the stack.
TIBCO → Wasola migration
Migrated legacy SOAP-based TIBCO integrations to RESTful Wasola services by extracting transformation logic and orchestration into a dedicated microservice — enabling clean, incremental removal of the monolith without a big-bang rewrite.
Data layer optimisation
Targeted optimisation of the data layer to improve query performance and throughput across transactional and distributed data stores.
