Business Analysis and Planning
Discovery, requirements, scoping
Product discovery, stakeholder interviews, requirements engineering, and technical scoping. We define what to build and why before writing a single line of code.
TMS Outsource is a custom software development agency founded in 2014, with engineering offices in Belgrade, Serbia and Bucharest, Romania. We plan, build, support and enhance web and mobile applications for fast-growing tech companies across Europe and North America. What started as a team building its own web products has grown into a 40-person engineering organization that has shipped software used by more than 4 million people worldwide.
The numbers behind TMS Outsource. Ten years of building production software, verified by independent review platforms.
Full-stack developers, front-end engineers, mobile developers, QA specialists, DevOps engineers, and Scrum Masters. Every project team is assembled from specialists matched to the technical requirements of the work.
Per engineer. Senior developers lead every engagement, with mid-level and junior engineers contributing under structured code review and mentorship. We do not staff projects with only junior developers to cut costs.
TMS has been delivering production software for over 10 years. The company was founded to build its own web products and evolved into a full-service development agency serving clients across Europe and North America.
Across Europe, North America, and the Middle East. We work with early-stage startups, scale-ups, and enterprise clients. The common thread is that they all need production-grade software, not prototypes.
Combined active installations across TMS-built WordPress products. Amelia (1.5M+) and wpDataTables (2.7M+) are used by websites in 50+ countries. These are real production products with real users, not portfolio demos.
Verified by independent B2B review platforms. 5.0 stars on Clutch (20+ client reviews) and 5.0 rating on GoodFirms. These are public, verified reviews from real clients, not self-reported testimonials.

Alexander Gilmanov founded TMS Outsource in 2014 with a focus on building production-grade web software rather than simple websites.
Founder and CEO
Alexander founded TMS Outsource in 2014 with a focus on building production-grade web software rather than simple websites. He holds a Ph.D. and brings over 15 years of experience in software architecture, team building, and product development.
Under his leadership, TMS has grown to 40+ engineers and shipped products used by more than 4 million people worldwide. The company's two flagship WordPress products, Amelia and wpDataTables, are actively maintained and continue to grow their user base year over year.
Alexander remains actively involved in technical architecture decisions across major client engagements, particularly in the early scoping and architecture phases where the cost of getting things wrong is highest.
Seven service lines, all delivered from the same engineering organization. No subcontractors, no outsourcing beyond our own team.

Our production stack. We work with these technologies every day, not just on paper. Stack selection is driven by project requirements, not preference.
React, Vue.js, TypeScript, Next.js, Tailwind CSS. We build responsive, accessible interfaces with component-based architecture and state management suited to the application's complexity.
Node.js, PHP/Symfony, Laravel, Python. REST and GraphQL APIs, microservices, and monoliths. We choose the architecture that fits the problem, not the one we default to.
PostgreSQL, MySQL, MongoDB, Redis. Relational and document databases, caching layers, and search infrastructure. Data modeling decisions are made based on access patterns, not trends.
AWS, Docker, Kubernetes, CI/CD pipelines. Infrastructure as code, automated deployments, monitoring, and scaling. We handle the full operational lifecycle, not just initial deployment.
React Native, Swift, Kotlin. Cross-platform and native mobile development. We ship to both App Store and Google Play with the same engineering standards as our web work.
Figma, Maze, Cypress, Playwright. Design systems, prototyping, and automated testing. QA is embedded in the development process, not bolted on at the end.
In addition to our client work, TMS runs one of the most comprehensive independent editorial resources for software developers, mobile app users, and tech teams.
Since 2019, our editorial team has published and maintained 500+ in-depth articles covering developer tools, mobile app management, AI coding assistants, software development methodologies, and app ecosystems, read by over 1 million developers and tech professionals annually.
We test and compare the tools developers actually use every day: VS Code, PyCharm, Cursor, GitHub Copilot, Windsurf, Claude Code, JetBrains IDEs, and more. Our comparisons are based on firsthand use by engineers on our own development team, not summaries of other articles.
Our team evaluates AI coding tools, vibe coding platforms, and agentic coding environments as they emerge. We publish structured comparisons, real-world usage reviews, and original analysis on how these tools affect developer productivity and code quality.
We cover iOS and Android app management in depth: permissions, parental controls, privacy settings, sideloading, and app store dynamics, documented against real devices with every major OS update.
From Scrum and Agile to DevOps, CI/CD, microservices architecture, and software quality models, we publish reference-grade explainers grounded in our team's production experience.
Every article published on the TMS blog meets the following criteria.
Procedures and tool behaviors are tested on real devices or in real development environments before publication.
Articles covering tools, apps, or platform behavior are reviewed and updated with each major release cycle.
Where we include affiliate links, editorial assessments are made independently of commercial relationships.
Articles on developer tools and software methodology are authored or reviewed by engineers with direct experience using the tools in production.
Claims about tool behavior, statistics, or platform data are linked to primary sources or documented from firsthand testing.
When we get something wrong, we fix it. Errors are corrected promptly with a dated changelog entry noting what was updated and why, so readers can trust the current version of any article.
Our editorial contributors are working software engineers, mobile developers, and QA specialists, the same team that builds production applications for our clients. This means our developer tool reviews and methodology articles come from people who use these tools on real projects, not from generalist writers summarizing documentation.
