Three things, done properly.

Not a menu of everything I can do — the three I keep getting hired for. Each one has a real example behind it, not a buzzword list.

01 ongoing

Email deliverability & inbox infrastructure

  • Build and operate live email platforms end-to-end
  • Recover blacklisted IPs and warm them back to inbox
  • DKIM / SPF / DMARC setup, feedback loops, suppression hygiene
  • Sender reputation monitoring + reactive fixing when it tanks
real example

Email deliverability work across production systems: DNS authentication, reputation monitoring, IP warmup, blacklist recovery, and the 2am debugging that keeps mail moving.

02 project / ongoing

API tooling & backend systems

  • Design and ship REST APIs that survive real traffic — AWS Lambda serverless included
  • Trigger-routing systems that tie services together without duct tape
  • Salesforce CRM integration, payment gateways (Axis / PayU / Paytm), auth & caching
  • Developer-facing tooling that other engineers actually want to use
real example

ProWebLook — 12 API tools shipped and running on CodeIgniter + AWS Lambda, DA 12. Also shipped Salesforce CRM integration for Anant University's admission portal — automated lead-to-student conversion end-to-end.

03 project

Production firefighting & cloud scale

  • AWS infrastructure (EC2, S3, RDS, CloudFront) — designed, managed, rescued
  • Disk-full at 2am, OOM kills, runaway queues — diagnosed and stopped
  • Laravel / MySQL at scale: slow queries, index debt, locking drama
  • CI/CD pipelines (GitHub Actions), n8n automation, Datadog/NewRelic observability
real example

Plaksha University: managed AWS infra for 10+ apps, ran a Moodle LMS for 5,000+ users at 99.9% uptime, cut deployment times 30% with CI/CD, and saved 20+ hours/month automating workflows with n8n. AWS Certified.
