Start with the situation
Share the users, constraints, and what already exists. A clear account of the difficulty is more useful than a polished pitch.
Independent engineer · Baku
Thoughtful software for systems that need to last
I work with teams on software, infrastructure, and hardware where reliability matters after launch as much as it does on launch day. If you are working through a difficult technical problem, I would be glad to hear the context.
A working note
Good engineering is often quiet: clear choices, dependable systems, and room for the people who come next.
Now
CTO advisor at DigiSmart Tech, working across technical strategy, architecture, and delivery.
Previously
Led mobile engineering at PASHA Bank, supporting more than 140 services and approximately 250,000 monthly active users.
In practice
This site runs on Docker, Nomad, and Consul — the same operational principles I bring to client work.
Working style
Small, focused engagements with clear ownership, careful decisions, and respect for the people who maintain the work.
Materials
A practical range of tools and disciplines, shaped by products I have shipped, operated, and studied closely.
Mobile
Native Android and iOS for payments, provisioning, and products that need to remain dependable in daily use.
Services
APIs, BFFs, and microservices — the contracts that keep clients, data, and teams moving together.
Data
SQL, NoSQL, and graph systems, including benchmarks of Neo4j, TigerGraph, and Oracle PGX on fraud workloads.
Runtime
Docker, Nomad, Consul, Vault, and Terraform, with an emphasis on repeatable operations.
Identity
Keycloak and application security, including the practical questions that come with review and audit.
Hardware
Arduino, Raspberry Pi, and programmable chips for work that benefits from a connection to the physical world.
Quality
Automated testing, performance, and operational behavior considered together rather than as a final pass.
Selected work
Work shaped by real constraints

Kvik
Led the Android implementation of a phone-number-based bank card with no-fee transfers. The first two months brought 4,000 registered cards, supported by careful attention to onboarding, KYC, and the less visible parts of the experience.

Laser area meter
An Android app that calculates area from a smartphone and a laser distance meter, built with Sumaks Technology. A practical example of the same interest in software that connects cleanly to the physical world.

Appar TV
Android client for a live trivia show, with real-time video over WebRTC and messaging over pub/sub. The service supported approximately 3,000 daily players at 99.89% crash-free sessions.
How projects take shape
A considered process leaves room for judgment, evidence, and the realities of operating software.
02
Make the important decisions explicit
We establish what matters, what can wait, and where uncertainty lives. The right size and stack follow from that understanding.
03
Build carefully, then test the edges
The work is implemented with attention to its architecture, everyday operation, and the quiet failure modes that only appear after launch.

A good technical conversation can start simply.
I advise as CTO at DigiSmart Tech and previously led mobile engineering at PASHA Bank. If the work would benefit from a second perspective, email is the best way to reach me.
