Who is Alok Sharma (alokscott)?

Alok Sharma — known online as alokscott — is a Delhi-based Technology Consultant with over 10 years of professional experience. He designs and delivers cloud-native, scalable web applications and APIs, and currently leads engineering as Technology Head at Kairos Marcom.

What does Alok Sharma do?

He builds software end to end: REST API architecture, ERP and CRM platforms, eCommerce systems, Web3 and blockchain applications, and AI/LLM-integrated products. His work spans the full SDLC — solution architecture, database optimisation, containerised deployment and CI/CD — as well as leading and mentoring engineering teams.

What technologies does Alok Sharma work with?

PHP 8.x, TypeScript, Node.js, Python and Angular on the application side; Solidity, Web3.js and Ethers.js for blockchain; Microsoft Azure, Docker, AKS, CI/CD and GitHub Actions for cloud and DevOps; MariaDB, MySQL and PostgreSQL for data; plus AI and LLM integration.

Does Alok Sharma build blockchain and Web3 applications?

Yes. He develops Solidity smart contracts, token systems, wallet integrations and DeFi features, and has built a full cryptocurrency trading platform with live market data and on-chain token swaps.

Do you work with clients in the US and UK?

Yes. Alok works remotely with companies in the United States and the United Kingdom, alongside clients in India. Engagements run fully remote — video calls, shared repositories, and your existing project tooling (Slack, Jira, Linear, GitHub). Contracts, NDAs and IP assignment agreements are standard and welcome.

What timezone do you work in, and will our hours overlap?

Alok is based in Delhi, India (IST, UTC+5:30). That gives a natural overlap with UK business hours for most of the working day, and with US Eastern mornings. For US West Coast teams he keeps a late-evening IST window. Overlap hours are agreed up front and written into the engagement, not left to chance.

How do payments and contracts work for international clients?

Fixed-scope engagements are quoted in USD or GBP and invoiced up front or in milestones. Payment by international bank transfer, Wise or Stripe. Standard contract, NDA and IP-assignment paperwork is signed before work begins, so all deliverables and source code belong to you.

Is Alok Sharma available for hire?

Yes. He takes on fixed-scope consulting engagements — performance audits, architecture and code reviews, AI integration sprints — as well as monthly technical retainers and longer contract work. He is also open to senior engineering and technical leadership roles.

Why is my PHP-FPM server running at 100% CPU?

Usually it is not the traffic — it is the configuration. The common causes are OPcache being disabled or undersized (so PHP recompiles every script on every request), a PHP-FPM process manager tuned wrongly for the available RAM, and a MariaDB or MySQL buffer pool too small for the working set, which pushes reads to disk. Alok has taken a production server from 95%+ sustained CPU down to stable under full load by fixing exactly these three, plus adding swap headroom. A Performance & Infra Audit diagnoses which of them is hurting you.

How do I reduce high server CPU load on a PHP application?

Measure before you change anything. Profile the application to find the slow paths, check whether OPcache is enabled and large enough to hold your codebase, review PHP-FPM pm settings against your actual memory, then look at slow queries and missing indexes — an unindexed query on a growing table is the single most common cause of a server that used to be fine. Alok has achieved an 8x query speed improvement through index and query work alone.

Can you audit or review our existing codebase before we scale?

Yes — that is the Architecture & Code Review engagement. It is an independent read on your REST API design, data model, security posture, dependency risk and the bottlenecks that will bite you at 10x traffic, delivered as a prioritised roadmap your own team can execute. It is commonly used before a funding round, before a rewrite, or when a team inherits a codebase they did not write.

Crypto Exchange Development Case Study — coinswift.exchange

A production cryptocurrency exchange — live market data, secure transaction handling, and one REST API backing both web and mobile clients.

The brief

Build a working cryptocurrency exchange — not a prototype. Real-time market data, transaction flows that hold up under scrutiny, and a REST API back end that serves web and mobile from one contract.

Why exchanges are unforgiving

Prices move constantly, so the data path has to be genuinely real-time rather than polled-and-hoped — a price that is three seconds stale is not a price, it is a liability. Money movement has to be correct under concurrency: a race condition in a trading flow is not a bug you patch next sprint, it is a loss. And one API has to serve web and mobile without quietly forking into two back ends that drift apart.

Those three constraints drive nearly every architectural decision on a project like this — and getting them wrong is expensive in a way most web work is not.

The result

coinswift.exchange runs in production, handling real-time trading flows, with one REST API back end serving both web and mobile clients.
