Engineering Manager

Building Scalable
Solutions & Teams

Engineering Manager with 13+ years of experience building and scaling engineering organizations from early-stage to production-grade. Joined Techno Exponent in 2015 as a founding engineer and built the DevOps and SRE practice from scratch, one engineer, one pipeline, into a mature function supporting 150+ engineers and multiple simultaneous client deployments. Works best at the intersection of technical depth and team clarity, where architecture decisions and people decisions are part of the same conversation.

Engineering Manager, Cloud and Web Apps
Techno Exponent (T-Web Exponent Services Pvt. Ltd)
Sep 2020 - Present
5+ years
  • Played a central role in scaling the company from 14 to 150+ engineers as a founding tech leader, shaping hiring standards, team structure, and technical practices across cloud, backend, DevOps, and SRE.
  • Directly led teams of 4 to 8 engineers across four concurrent client engagements, delivering 21 client projects over five years while owning technical delivery, architecture decisions, and team culture.
  • Built the DevOps and SRE practice from scratch, taking deployment frequency from one release per week to 3 to 6 releases daily in dev and 1 to 2 daily in production. P1 incidents reduced from several per month to near zero after SRE practices were fully established by 2022.
  • Improved release quality by introducing automated test coverage (Jest, Cypress) and code quality gates (SonarCloud) across all active projects.
  • Led AI integrations including RAG-based legal document search (Pinecone and OpenAI), Whisper AI transcription pipeline for video evidence, and LLM-assisted writing tools using AWS Bedrock.

Key Engagements

Three of the engagements that shaped the DevOps and SRE practice.

ZLS.app
LegalTech - United States
DevOps and AWS Consultant

Engaged from inception. Owned AWS ECS and ECR infrastructure with capacity providers for mixed instance types. Implemented a full compliance stack: EBS encryption, S3 lifecycle policies, AWS KMS, WAF, OpenVPN with private RDS, and Secrets Manager. Supported Whisper AI transcription pipeline and a FastAPI-based data migration service for legal office record import. Ensured every layer of a sensitive legal platform was secure and compliant before real client data touched it.

Claims Service International
InsuranceTech - United States
DevOps Consultant and Infrastructure Lead

Three-year engagement. Owned the full AWS stack: EC2, RDS, S3, Secrets Manager, Route 53, ALB, ACM, and SES. Led zero-downtime migration of a 30GB production MySQL database to AWS RDS via DMS. Embedded in the delivery team through a full-stack rebuild from PHP to Node.js and Angular, owning all AWS deployments end to end. The hardest part was bringing clarity into ambiguity and keeping a cross-functional team aligned when the path forward was not obvious.

CECAM
Scientific Research - Switzerland
Technical Lead, Infrastructure Owner, Team Manager

Mixed role reporting directly to the CTO on architecture and team decisions. Led a team of one full-stack developer, one designer, and one tester. Owned complete development and production environments on on-premise Linux servers behind a CISCO VPN. Led end-to-end modernization of CECAM's conference management platform from a legacy codebase to a modular, RESTful application in Laravel and Node.js.
