TECHNICAL ARCHITECTURE DECISIONS
  • Apache Kafka Streaming: Decoupled high-frequency charging telemetry and payment validation from HTTP request-response chains, handling traffic bursts smoothly.
  • Redis Sentinel In-Memory Caching: Achieved sub-millisecond session lookup on high-traffic charger status endpoints, reducing database read load by over 70%.
  • PostgreSQL Query Optimization: Redesigned composite indexes and partitioned high-write transaction log tables to eliminate lock contention.
  • Kubernetes (EKS) Horizontal Pod Autoscaling: Configured proactive CPU/memory threshold scaling with zero dropped requests during sudden load spikes.

CONTEXT & CHALLENGE

Bridging High-Speed Demands with Engineering Sanity

Transitioned from senior engineering to Technical Product Manager. Rapidly expanding operator accounts requested disparate features without unified architectural standards, risking codebase divergence.

OWNERSHIP & ROLE

Technical Product Manager

Directed whole-product lifecycle: customer discovery interviews, data-driven feature scoring (RICE/Value-Effort), technical PRD documentation, sprint commitments, and release governance.

KEY DECISIONS & FRAMEWORKS
  • Contract-First PRD Standard: Established rigid PRD templates detailing data models, edge cases, failure states, and acceptance criteria before sprint planning.
  • Telemetry-Driven Roadmap Prioritization: Replaced subjective opinions with actual telemetry logs, driver drop-off funnels, and operator support tickets.
  • Platform Reliability Over Shiny Velocity: Established a 20% dedicated capacity buffer per sprint specifically for tech debt, database indexes, and resilience.
MEASURABLE OUTCOME
5× Increase in concurrent sessions
−40% PRD clarification churn
100% On-time quarterly OKR delivery
CONTEXT & CHALLENGE

Physical Hardware Quirks in a Digital Cloud

Connecting thousands of physical chargers from 10+ hardware manufacturers running different firmware versions revealed continuous non-compliant JSON payloads and dropped WebSocket connections.

OWNERSHIP & ROLE

Protocol Architect & Product Owner

Authored protocol adapter specifications, led integration testing in physical charger test benches, and engineered abstraction adapters isolating core charging logic from messy charger firmware.

ENGINEERING HIGHLIGHTS
  • State Machine Fault Tolerance: Created an asynchronous state machine with reconciliation timers that cleanly handle unexpected offline events mid-charge.
  • OCPP 1.6J to 2.0.1 Pathway: Designed a bidirectional message translator enabling forward-compatibility with advanced smart charging profiles.

MEASURABLE OUTCOME
−65% Hardware onboarding time
99.8% Session message delivery rate
CONTEXT & CHALLENGE

Complex Multi-Party Monetization

EV pricing is multidimensional: base connection fees, energy consumption (kWh), time-of-use peak surcharges, and parking penalties, followed by fractional revenue splits among site owners and grid utilities.

OWNERSHIP & ROLE

Fintech Product Owner

Owned the tariff configuration engine, financial settlement math, and tax calculation modules with zero tolerance for floating point rounding discrepancies.

About & Principles

Deepak Bharadwaj

Deepak Bharadwaj

Engineer by training · Product Manager by trade
Bangalore, India · 9+ Years Building Platforms

I cut my teeth in deep enterprise systems engineering at SAP Labs, mastering distributed concurrency, relational database indexing, and the unyielding demands of mission-critical banking connectors.

Over the past four years in the fast-moving EV charging software space, I stepped into technical product management—where business goals, unit economics, and complex distributed architectures collide.

I thrive on turning messy technical ambiguity into dependable software that solves customer problems. I believe in high agency, radical candor, and engineering teams that own their outcomes from commit to production.

Operating Principles

  • High Agency & Ownership: Take extreme responsibility for the problem, the solution, and the post-launch metrics.
  • Simplicity Over Premature Abstraction: Solve the actual problem directly before introducing unnecessary architectural layers.
  • Data-Informed, Decisive Prioritization: Combine user telemetry with sharp intuition to make fast, unambiguous calls.
  • Reliability Is a Feature: Velocity means nothing if the system degrades under real-world driver peaks.
  • Transparent Cross-Functional Alignment: Clear technical PRDs bridge business strategy with engineering execution.

Honors & Recognition

  • SAP Catalyst Award (2020) Recognized by executive leadership for outstanding engineering velocity and banking connector reliability.
  • Appreciation Letter, RubyPixels (2017) Commended for foundational software architecture and high contribution cadence.
  • Best Outgoing Student Award (2012) Honored for academic excellence and leadership.
