Hi, I'm Himanshu
Sharma
I design scalable backend platforms, distributed systems, and enterprise-grade APIs powering modern digital products at scale.

Building systems that
scale like galaxies
With over 10 years of engineering experience, I specialise in designing and delivering distributed backend platforms that power enterprise products across banking, automotive, sports, insurance, and spiritual-tech verticals.
I've led engineering teams at scale, architected microservices platforms from ground up, and worked closely with product, DevOps, and business stakeholders to transform complex requirements into elegant, maintainable systems.
My approach combines deep technical rigour with systems thinking — treating every API as a product, every service boundary as a decision, and every deployment as a learning opportunity.
Architecture Expertise
From API design to infrastructure automation — the full spectrum of backend platform engineering.
Microservices Architecture
Designing domain-driven service boundaries, event-driven communication, and resilient fault-tolerant topologies.
Distributed Systems
CAP theorem, consensus algorithms, eventual consistency, distributed transactions, and partition tolerance strategies.
API Platform Engineering
RESTful & GraphQL API design, versioning strategies, developer experience, gateway patterns and API-as-product thinking.
Backend Scalability
Horizontal scaling, database sharding, caching strategies, load balancing, and performance profiling under high concurrency.
Cloud Infrastructure
Multi-cloud architecture on AWS & Azure, IaC with Terraform, containerisation with Docker/Kubernetes, and CI/CD pipelines.
High Availability Systems
99.99% uptime SLAs, circuit breakers, chaos engineering, blue-green deployments, disaster recovery, and observability stacks.
System Design Case Studies
Deep-dives into real architectural challenges, trade-offs, and the systems built to solve them.
Axis Bank — KYC Platform
Manual KYC onboarding taking 3–5 days, high drop-off rates, compliance gaps, and no real-time validation pipeline.
Event-driven microservices pipeline with async OCR processing, rule engine for compliance checks, and real-time status webhooks reducing onboarding to under 4 minutes.
Hero MotoCorp Platform
Legacy monolith unable to handle seasonal demand spikes (>500K concurrent users during product launches), with 40% uptime degradation.
Phased strangler-fig migration to modular microservices, horizontal auto-scaling on AWS ECS, CloudFront CDN, and distributed caching achieving 99.95% uptime.
IPL & BCCI Data Systems
Real-time score ingestion and fan-facing APIs collapsing under IPL live match traffic — 1M+ concurrent users with sub-500ms SLA requirements.
Read-optimised CQRS with dedicated read replicas, Redis sorted sets for live scorecard, SSE for real-time fan updates, and pre-warmed Lambda endpoints for burst traffic.
ClaimAssist Fintech Platform
Manual insurance claim workflows with 12-day average resolution, fraud detection gaps, and no unified data model across 8 insurer integrations.
Saga-based distributed transaction orchestrator for multi-step claim workflows, ML-powered fraud scoring pipeline, and unified adapter pattern for insurer APIs — cutting claim resolution to 48 hours.
Jyotirling Platform — Spiritual Journey App
Building a real-time pilgrimage guidance platform for millions of devotees across 12 Jyotirlinga sites — with offline capability, live temple updates, and e-commerce for puja bookings.
Progressive web app with service workers for offline mode, geo-fenced notification engine, multi-currency Razorpay integration, and a headless CMS for temple content managed by priests.
- ✦500K+ active pilgrims on platform
- ✦Real-time temple status updates < 2s latency
- ✦₹2Cr+ puja bookings in first year
- ✦Offline-first architecture for rural connectivity

Engineering Philosophy
Technology and nature share the same principle: complex systems emerge from simple rules.
The best architectures are those that feel inevitable in hindsight — born from constraints, shaped by empathy for the developer, and designed to evolve gracefully with changing business needs.
Engineering Writing
Sharing learnings from designing systems at scale — architecture patterns, trade-offs, and engineering leadership.
Designing Microservices at Scale: Lessons from 1M+ User Systems
Key architectural decisions — service boundaries, data ownership, async vs sync communication, and avoiding the distributed monolith anti-pattern.
Handling Traffic Spikes: A Practitioner's Playbook
From IPL live matches to bank marketing campaigns — practical patterns for pre-warming caches, circuit breaking, and graceful degradation under load.
API Architecture Patterns Every Senior Engineer Should Know
REST vs GraphQL vs gRPC, versioning strategies, backward compatibility, contract testing, and treating your API as a product — not a CRUD interface.
