Projects

Client platforms and distributed engineering projects delivered across cloud ecosystems.

Client Project · Kairos Technologies Nov 2024 – Sep 2026

EV Charging Backend & Integration Platform

Problem: Distributed EV charging networks faced high API response latency, multi-location contract data collisions, and unmonitored charging session states.
Contribution: Designed HLD/LLD for Go microservices, automated S3-to-database ingestion, implemented OCPI-based CPO integrations, and built Prometheus & Grafana observability dashboards.
Measurable Result: Halved data crunch time by 50% (6h to 3h), slashed recurring cron runtime to 20 minutes, resolved multi-location contract collisions, and enabled real-time dual-tariff tracking.

Healthcare Cloud Migration & Backend Services

Problem: High-compliance healthcare records were locked in legacy on-premises systems requiring schema normalization and zero-downtime migration.
Contribution: Engineered automated ETL pipelines and modular REST backend services in Go using Gorilla/Mux, GORM, and MongoDB; established test mocking with Testify and standardized CI/CD via GitLab & Harness.
Measurable Result: Migrated 200K+ healthcare records to AWS with 100% deployment uptime, improved code test coverage, and automated deployment pipelines.

Banking Transaction & Ledger Processing Platform

Problem: High-volume financial transactions required strict SLA compliance, asynchronous task prioritization, and low-latency ledger synchronization across retail dealer branches.
Contribution: Engineered core transaction and ledger processing engines on the Evo SaaS platform using Go, Java/Spring Boot, and AWS serverless (Lambda, DynamoDB); built an API caching layer with Redis.
Measurable Result: Scaled ledger workflows across 150+ retail dealer branches, reduced API response latency by 40% on high-traffic endpoints, and eliminated SLA processing bottlenecks.

About Me

Background, engineering philosophy, and academic foundation.

Deepanshu Gupta portrait

I am a Senior Backend Engineer with over 6 years of experience architecting and operating resilient cloud services and distributed systems. My primary focus centers on Go (Golang), gRPC/Protobuf, and AWS architectures.

Over my career spanning Kairos Technologies, Collabera Digital (now Ascendion), and Coforge, I have tackled high-throughput transaction processing, complex zero-downtime database transformations, automated ETL pipelines, and recurring cron optimizations. I place high value on defensible architectural choices (HLD/LLD), thorough test coverage with Testify, and full-stack observability with Prometheus and Grafana.
