Fractional CTO for
Ambitious Startups.
I help pre-seed to Series A founders solve their core technical problem and scale without full-time executive overhead. You get hands-on architectural ownership from an engineering leader with 12+ years of experience across commerce, logistics, and fintech.
01 THE CORE PROBLEM
Why agencies fail
and founders get stuck.
Most software agencies fail founders because they build features blindly without understanding unit economics or business models. Founders get stuck refereeing technical arguments, managing freelancers, and firefighting bugs.

02 CORE DOMAINS
Three industries where
I have deep operational experience.
Tested in high-volume, real-world systems at Indian tech leaders.
Commerce & Quick-Commerce
Order management systems (OMS), real-time inventory allocation across dark stores, high-concurrency cart pipelines, and coupon validation.
Explore Commerce Practice →Logistics & Last-Mile
Automated driver dispatch, bipartite matching algorithms, GPS telemetry filtering, and real-time SLA tracking across fleets.
Explore Logistics Practice →FinTech & Micro-Lending
Double-entry transactional accounting ledgers, algorithmic credit underwriting, automated KYC pipelines, and payment reconciliations.
Explore FinTech Practice →03 DEEP DOMAIN EXPERTISE · LIVING BLUEPRINTS
Proven architectures from
Blinkit, Porter & Urban Harvest.
Explore production system topologies, data consistency guarantees, and failure-mode defenses across quick-commerce, high-throughput fleet dispatch, and fintech lending.
2-Phase Distributed Hold & Dark Store Routing Topology
When 5,000 users attempt to purchase the last 12 units of an item during a flash sale, naive SQL updates cause database table lock-ups and negative inventory. We deploy an atomic Redis hold token mesh before touching persistent PostgreSQL records.
Optimistic Cart Hydration
Items added with soft lock tokens. Cart validation executes at edge in < 12ms without triggering heavy warehouse queries.
2-Phase Inventory Reservation
Atomic DECRBY with 7-minute lease TTL. If count drops below zero, rollback is instantaneous with zero row lock contention.
Dark Store Proximity Router
Selects the nearest dark store with complete basket coverage. If split required, optimizes pick-and-pack routing sequence.
Asynchronous OMS Commitment
Payment authorization publishes OrderPlaced event. Inventory committed to durable relational store with zero checkout latency penalty.
04 DELIVERABLES
Tangible artifacts,
not vague advice.
Every deliverable is documented in clear, reproducible specifications and committed directly into your repository.
Core Business Problem & Technical Diagnostic Brief
Deep audit of your customer funnel, unit economics, codebase bottlenecks, data models, and team velocity to uncover the real problem holding back growth.
Technical Architecture & System Blueprints
Detailed system blueprints covering OMS inventory holds, driver dispatch matching, double-entry financial ledgers, and database schemas with zero vendor lock-in.
Direct Hands-on Code & Pull Request Reviews
Umesh Gupta directly reviews and signs off on critical PRs, data schema migrations, security boundaries, and performance benchmarks.
Engineering Hiring & Team Scaffolding
Vetting senior engineering candidates, conducting rigorous technical interviews, and onboarding talent into a high-craft engineering culture.
Global Delivery & Commercial Agreement
Standard work-for-hire bilateral IP assignment, multi-currency invoicing, and clear milestones.
05 TRANSPARENT PRICING

06 QUESTIONS & ANSWERS
Frequently asked
questions.
Why hire a Fractional CTO instead of a full-time CTO or traditional agency?
A full-time CTO costs $350k+ per year in salary plus equity, and takes months to recruit. A traditional agency will assign junior developers and build tickets without understanding your business model. As your Fractional CTO, Umesh Gupta brings 12+ years of engineering leadership (ex-Blinkit, ex-Porter, ex-Urban Harvest) on Day 1 at a fraction of the cost with zero equity dilution.
What are your core engineering specialties in E-Commerce, Logistics, and FinTech?
Our work spans three verticals: 1) E-Commerce & Quick-Commerce: 2-phase dark store inventory allocation, coupon AST evaluation, fast checkout, and multi-warehouse sync. 2) Last-Mile Logistics: Kuhn-Munkres bipartite fleet matching, Uber H3 spatial indexing, and GPS telemetry. 3) FinTech & Micro-Lending: Double-entry ledgers enforcing Sum(Dr) = Sum(Cr), integer micro-currency math, and algorithmic underwriting.
How do you work with international clients across the US, UK, Europe, and UAE?
We operate with standard bilateral IP assignments, settle in USD, AED, GBP, EUR, and INR, and offer daily synchronous timezone overlap: 1.5 hours difference with UAE (Dubai/Riyadh), 4–5 hours with London/Europe, and morning overlap with US East Coast (EST).
How do you understand our core business problem before writing code?
We do not treat engineering as an isolated ticket factory. We start by auditing your growth bottleneck: Is customer acquisition bleeding because of slow load times? Is churn happening due to broken transactional workflows? Are cloud costs eroding unit economics? Once we identify the real leverage point, we design and ship technology that directly moves business metrics.
Can you help us hire and scale an in-house engineering team?
Yes. We design the hiring rubric, source and interview senior engineering candidates, evaluate live technical submissions, and establish clean engineering documentation so your internal team scales with high velocity and zero technical debt.
