About

I build and scale the backend systems that move money.

With 6.5+ years across fintech, crypto, supply chain and proptech, I take systems from whiteboard to production — and own them on call. Event-driven pipelines, real-time delivery and PCI DSS–compliant APIs behind them. Honest numbers, no surprises.

Now Solo-building torek.app — an AI interview-coaching product. RAG-grounded answers, golden-set LLM evals, shipped end-to-end.

Senior Software Engineer
ZenKoder · Remote, IN · client Blackpoint
2025 → NOW
  • 80+ MSP partners · ~$6–7M ARR — lead 3 engineers across 3 projects building Blackpoint’s billing & account infrastructure on Node.js, MongoDB, PostgreSQL and Kubernetes.
  • 7 partner integrations — built the Pax8 and ConnectWise integrations that let MSPs bill end users, plus 5 more security integrations (Bitdefender, CyberCNS, Cisco Umbrella) across those 80+ MSPs.
  • MTTR ~6h → 2–3h — alerting dashboards, centralized logging (Prometheus/Grafana) and OpsGenie on-call incident response.

Senior Software Engineer
CapGrid · Gurugram, IN
2023 → 24
  • −15% excess inventory — led 7 projects with a team of 5 and designed the cross-functional inventory optimization tool.
  • −20–25% supplier pricing — ran competitive RFQs and drove margin growth.
  • Days → minutes to insight — shipped an LLM-powered analytics tool on ClickHouse so the business team could query data in natural language.
  • Built the portal connecting clients and suppliers to the ERP, raised code quality through reviews and mentorship, and ran first-round technical interviews for engineering hires.

Software Engineer
IXFI · Ahmedabad, IN
2022 → 23
  • 30K → 200K users — shipped referral, reward points and gamification features: a real-time rewards/coins leaderboard (Redis), ticketing, contact management and a 2FA-removal workflow.
  • Horizontal WebSocket scale-out — Redis Pub/Sub decoupled connection handling from message fan-out, preserving per-connection state and ordering.
  • Sub-second market data — TimescaleDB for accurate OHLC charts, atomic/idempotent APIs, caching, indexing and schema versioning.
  • Shipped security hardening — input sanitization, NoSQL-injection prevention and PCI DSS compliance.

Software Engineer
Hyblock Capital · Noida, IN
2020 → 22
  • 20–30 crypto indicators — streamed through a Node.js socket client to Kafka for real-time analytics.
  • 2–3M hits/month — caching cut historical-data-query latency and DB load across the real-time analytics stack.
  • Built an automated Bybit trading engine executing on Hyblock indicators with execution-latency and reliability monitoring.
  • Engineered the Node.js WS→Kafka data backbone with connections, msg/sec, p95, reconnect and error-rate monitoring.
