Technical Lead / Staff Engineer

Engineer.
Leader.
Builder.

I lead engineering teams and ship products that scale to millions. 10+ years turning ambitious ideas into production systems at companies that matter.

About

I'm Hariom Sharma, a technical lead who bridges the gap between engineering execution and product strategy.

Over a decade shipping products for companies like Google, Telefonica, and high-growth startups. I architect systems, optimize performance, reduce costs, and build the teams that keep it all running.

System Architecture

Design scalable systems from scratch. Cloud infrastructure, microservices, performance at scale.

Team Leadership

Product Strategy

Define roadmaps, prioritize features with data, drive experiments that move business metrics.

Full-Stack Delivery

Web, mobile, APIs, infrastructure. Concept to deployment, no handoffs needed.

Cloud & Infrastructure

AWS (CloudFormation, Terraform), Cloudflare Workers, Supabase. Cost optimization and 20x scalability.

Developer Experience

AI & Tooling

AI-Augmented Engineering

I don't just use AI. I've operationalized it across entire engineering orgs. From development to QA to product, I've built workflows where AI is a team member, not a toy.

Most companies are still figuring out how to use AI. I've been integrating it into every stage of the software lifecycle -- with the human oversight and quality gates that keep shipping safe.

AI-Assisted Development

Architecture generation, code scaffolding, rapid prototyping. Using Claude, Cursor, and Copilot to ship 3-5x faster without sacrificing quality.

Automated Code Review

AI-on-AI review pipelines. Every PR gets AI analysis for bugs, security, and patterns before human review.

Test Generation & QA

AI-driven test case generation from specs. Edge case discovery, E2E scenario creation, and coverage analysis at scale.

Workflow Automation

CI/CD pipelines with AI gates, automated deployments, release notes generation, and incident triage across the entire SDLC.

Cross-Team AI Adoption

Rolling out AI workflows to product, design, QA, and ops teams. Training non-engineers to leverage AI for their own work.

AI-Native Architecture

Building systems with AI at the core -- MCP servers, agent workflows, RAG pipelines, and intelligent automation that compounds over time.
