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.

I've led teams of 15+ engineers, grown platforms from 10K to 400K+ users, and built products for Google and Telefonica. A decade at the intersection of hands-on engineering and technical leadership: architecting systems, optimizing performance, reducing costs, and building the teams that keep it all running.

System Architecture
Design scalable systems from scratch. Cloud infrastructure, microservices, performance at scale.
Team Leadership
Build, hire, and mentor engineering teams. Cross-functional collaboration with product and executives.
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.
Performance & Cost
Optimize load times, reduce cloud spend, improve conversion rates. Measurable impact.
Developer Experience
CI/CD pipelines, testing strategy, build tooling, coding standards. Make the team faster.

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.
In 2026, 93% of companies use AI in their workflows. I've been ahead of that curve, integrating AI 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 — catching issues earlier.
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.
