Chapter 01 — The Foundation
Deployed before it was a job title.
Tata Consultancy Services · Software Engineer · Jun 2015 – Jul 2020 · Chennai, India
Led the R&D and demo team presenting a POS solution to international clients — customizing the product to each client's workflow and making live feature changes during demos, based on real-time client feedback.
That is the Forward Deployed Engineer job description, eight years before the industry coined the title: sit with the client, understand the workflow, ship the change while they watch.
- Presented and demoed POS solutions to international clients across desktop and mobile as a technical advisor supporting pre-sales and product adoption
- Automated deployments with one-click scripts, cutting client rollout and implementation time by ~80%
- Led migration of the POS application from Angular to React, optimized for React Native integration — reducing maintenance headcount by ~30%
- Built a certification platform for skilled laborers in India, cutting human evaluator effort by 90%
- Trained 500+ engineers per batch, every 6 months for 4 years, on HTML, CSS, JavaScript, and React
Chapter 02 — Full-Stack, Full Ownership
Impact you can put a number on.
Walmart Global Tech · SDE III · Jul 2020 – Jun 2022 · Chennai, India
Owned complete systems end-to-end — Node.js backend APIs and React frontends — delivering the full pipeline from data layer to UI with a deep understanding of the operations teams using them.
During COVID, spotted that an enhanced employee insurance program could be delivered by extending Walmart's existing configurable forms platform instead of building a new app — integrated the insurer's APIs, auto-populated employee data from LDAP, and turned a manual multi-step process into a few-click experience. Recognizing reuse is a systems-thinking instinct, not a feature request.

Chapter 03 — Embedded in the Fire
Production-critical, zero-downtime, regulated.
UOB Bank · Senior Frontend Lead · Jun 2022 – Present · Singapore
Lead frontend engineering for Web Service Management platforms supporting retail and wholesale banking — thousands of daily active users, zero-downtime release requirements, and a regulator watching.
Drove a configurable multi-market platform transformation for Business Banking onboarding: replaced country-specific implementations with one scalable, configuration-driven solution — working end-to-end from discovery workshops through API design, pilot rollout, and production readiness, as the bridge between business stakeholders and multiple engineering teams.
- Own frontend architecture and production stability for TypeScript/React platforms serving thousands of daily users
- Led end-to-end response to a production OTP-abuse incident — detection, mitigation, and long-term hardening across four teams
- Partner with DevOps and infrastructure on observability, CI/CD, and zero-downtime release reliability
- Drive root cause analysis for frontend production incidents and preventive engineering
- Mentor engineers on advanced React patterns, performance tuning, and scalable UI architecture
⚠ incident replay — production OTP abuse
T+0 · Detect
Bot-driven SMS/OTP abuse identified
Spotted anomalous OTP traffic driving SMS cost and onboarding risk; confirmed bot-driven abuse targeting international destinations.
T+1 · Assess
Impact quantified across teams
Worked across business, infrastructure, backend, and operations to size the cost exposure and customer impact.
T+2 · Mitigate
Short-term containment
Coordinated with the SMS provider to block targeted international destinations, stopping the bleed within hours.
T+3 · Harden
Long-term fixes shipped
Drove IP tracking and rate limiting, OTP retry limits, stronger session validation, and CAPTCHA into production.
T+4 · Monitor
Post-deployment verification
Coordinated rollout and monitored post-deployment results until abuse traffic flatlined.
Chapter 04 — The Thesis
The industry invented a title for what he was already doing.
Forward Deployed Engineering means sitting with the client, understanding the workflow, and shipping production systems inside their constraints. Map the competencies to the career:
Chapter 05 — Hands-On
Don't read the resume. Query it.
