• Built Nexus (nexus.scalerailabs.com) end to end as the sole engineer — the enterprise data platform behind Evaratus's licensed data exports, since grown into a full org vertical staffed by a 15-person team driving 100M+ revenue per quarter.
• Own the LLM evaluation stack: pipelines with deterministic graders holding scoring variance under 2% across runs, plus automated validation that replaced manual review and lifted data approval rates 40%.
• Designed a reusable RL-environment framework — ~70% less setup time, repeatable versioned task setups for 10+ AI trainers — and built the Ray-based distributed compute platform that baselines RL tasks, cutting turnaround 3x.
• Led the engineering team behind PeakTalent (peaktalent.ai) — the marketplace that sources, tasks, and pays domain experts for AI training work.
• Led engineering for the enterprise data vertical — petabyte-scale, high-throughput pipelines for PII/BII detection & redaction; acted as forward-deployed engineer across 100+ enterprise accounts, from scoping to delivery.
• Standardized every partner environment in Docker (5+ external AI partner integrations) and built AWS Organizations tooling — CloudFormation StackSets with least-privilege IAM that clients run themselves for sizing and export.
• Added auth, structured logging & Datadog/PagerDuty alerting platform-wide, cutting MTTD; architected the internal task-management platform from scratch with a 4-person team, on schedule.

• Led the in-house CRM from inception — secure auth, reusable permission templates, and lead management (filtering, stage tracking, email, owner assignment).
• Built an AI-powered Sales Training platform (ElevenLabs + Gemini + Deepgram), improving sales productivity 1.5x and cutting ramp-up by 2 weeks.
• Led the Internal Meetings Platform — watermarking and interactive elements (polls, quizzes, surveys) serving 50,000+ active learners.
• Built an admin panel for assisted live-class workflows, cutting instructor onboarding 30% across 200+ instructors.
• Owned critical on-call (DB CPU/IOPS, Sidekiq queue depth); upgraded AWS RDS/Lambda to remove maintenance overhead.

• Led the Scaler Topics CS curriculum — maintained an average article rating of 4.6 across 1000+ articles.
• Managed 4 topics/quarter (Linux, Data Structures, OS, DBMS, React…), set up writer/reviewer hiring, and personally reviewed 25% of published articles.
• Led the USA launch of Scaler Academy — backend & frontend changes for the US region.
• Drove the Scaler Neovarsity initiative with Woolf University — hands-on low-level design & implementation.
• Hardened the platform with expanded Cypress + RSpec coverage and tracking across major flows.

• Product Lead for the mobile app — interactive live-video commerce that doubled (2x) user engagement.
• Led the React Native team — shipped a full iOS + Android app from scratch (React + Golang) with custom native components; integrated Google/Facebook APIs for live streaming to social platforms.
• Deployed Jitsi Meet on EC2 autoscaling — 500 concurrent users/session at 99.9% uptime.
• AWS: Lambda, API Gateway, CloudFront, CloudWatch, EC2, CloudFormation, S3, MediaLive, Route 53.

• Delivered 4 end-to-end software projects with cross-functional teams of 5–15 across data engineering and operations.
• Designed & deployed a field-facing automation tool for a multi-country pharmaceutical client — adopted by 5,000+ field users across 3 countries.
• Built automation scripts boosting operations efficiency, with successful large-scale go-lives.
