## About

Backend engineer with 3\+ years building distributed systems, real\-time pipelines, and LLM\-powered products at scale\. I specialize in high\-throughput backend systems and AI/LLM integration — from re\-architecting SSE pipelines and Kafka\-based ingestion systems to shipping conversational bots into production doubt\-resolution flows\. Some things I've shipped: — ⚡ \~94% CPU reduction by re\-architecting an SSE message handling pipeline \(45% → 2\.5%\) 💰 \~$6\.4K/month saved by migrating 7 ML models from SageMaker → CastAI on GKE 🔍 Real\-time Kafka \+ Elasticsearch search pipeline powering course discovery at scale 🤖 \~58% bot response coverage via LLM\-powered conversational flows in production 🧹 \~29% codebase reduction \(19K → 13K LOC\) through systematic deprecation Stack: Golang · Java · Python · Kafka · Redis · MongoDB · PostgreSQL · Elasticsearch · AWS · GKE · CastAI · Firebase 📬 tiwaresumit143@gmail\.com \| sumittiware\.netlify\.app

## Work experience

Software Engineer at ALLEN Digital, Jul 2024 \- Present · 2 yrs, Bengaluru, Karnataka, India, Doubts Service & LLM Integration: Built a Go microservice for real\-time doubt resolution using a hybrid conversational bot — combining intent classification, dialog flow routing, and LLM\-first generation with multi\-turn session memory\. Routed unresolved doubts to human teachers as fallback via an internal LLM gateway, achieving \~58% automated response coverage\. Workflow Orchestration Engine: Contributed to an internal config\-driven DAG engine \(Go/Kratos\) — JSON\-defined workflows, decision steps, retries, timeouts, and shared context\. Designed doubt\-resolution pipelines as declarative DAGs orchestrating LLM calls, SSE delivery, persistence, and metrics behind a single API\. SSE Pipeline Re\-architecture: Identified and eliminated a core bottleneck in the SSE message handling layer — reducing CPU by \~94% \(45% → 2\.5%\), ingress by \~54%, and egress by \~33%, enabling horizontal\-scale\-free growth\. Production Reliability: Built a Go\-routine manager with weighted semaphore control and context\-based cancellation — eliminating panic vulnerabilities and improving uptime on a high\-traffic service\. Search Indexing Pipeline: Built and extended an event\-driven indexing path — SQS consumer with batching and rate limits, MySQL as staging source\-of\-truth, and a cron worker bulk\-upserting/deleting in OpenSearch\. Instrumented end\-to\-end with OpenTelemetry tracing and metrics\. ML Infra Cost Optimisation: Migrated 7 ML models from SageMaker → CastAI on GKE with zero downtime, saving \~$6\.4K/month \(\~55% reduction\)\. Unified QC Platform & Codebase Health: Built a QC platform from scratch replacing fragmented workflows across engineering, product, DevOps, and QA\. Separately reduced the backend codebase by \~29% \(19K → 13K LOC\) through systematic deprecation\.

Software Developer at Alippo, Sep 2023 \- Jun 2024 · 10 mos, Bengaluru, Karnataka, India, Alippo Search \(Elasticsearch\) : Designed and built full\-text course search from scratch using Elasticsearch, integrated with a Node\.js ingestion server that synced data from PostgreSQL in real\-time\. Powered discovery across a large course catalog\. Server\-Driven UI \(SDUI\) Architecture : Designed a backend\-controlled UI rendering system enabling over\-the\-air layout changes without app releases — significantly reducing frontend deployment overhead\. In\-App Chat Community : Built a WhatsApp\-style real\-time chat platform supporting 1,000\+ DAU across 100\+ communities using Firebase real\-time messaging\. Observability and Monitoring: Set up a Logstash pipeline for centralized log management, enabling proactive monitoring of server errors and application health\. Maintained app stability at \~99\.6% by proactively monitoring Crashlytics and resolving production issues\.

Software Developer at Play GPL, Dec 2022 \- Aug 2023 · 9 mos, Bengaluru, Karnataka, India, Fullstack contributor \(Golang · Flutter · Next\.js\) across mobile, backend, and frontend\. — Built a Redis\-based Feed system and Expert Teams feature \(Dream11\-style\) using an event\-driven architecture — Developed an in\-house template\-based notification system using Go's Firebase Admin SDK with scheduled and automated delivery via go\-quartz — Built topic\-based user cohort segmentation for targeted notifications — Led mobile app development using MVVM \+ MobX \+ go\-router

Software Developer Intern at Play GPL, Feb 2022 \- Jul 2022 · 6 mos, Bengaluru, Karnataka, India, Startted working at Hoggy later moved to PlayGPL
